2 and higher), but only with d_type=true enabled. Ext4 tiene el registro en diario de forma predeterminada y es probable que los nuevos usuarios no sepan cómo deshabilitarlo para guardar lecturas / escrituras en sus. To format an xfs filesystem correctly, use the flag -n ftype=1. Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. Share. installs, natively. All my systems (4) have been using BTRFS for some time now without any issues. Btrfs, ZFS, and bcachefs are probably your best bets out of the 19 options considered. It has features that can scale better than ext4 and is even preferred over ZFS by some users. Rep: XFS has unbalanced performance, but in the best use case blows away many other formats. FreeBSD has ports you can install that will allow data transfer of some linux file systems. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. ext4 is an "advanced" version of ext3 with various improvements, basically an upgrade to the ext3 format. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. Ext4 is the default system for most Distros. Language: Format: Language and Page Formatting Options. This article provides a detailed comparison of XFS vs btrfs to help you determine which file system is a better fit for your use case. ago. In this test, Btrfs outperformed LVM in every benchmark. Furthermore, the Ext4 is designed to be backward compatible. I developed an application recently and compared the I/O performance of both and found ext4 to be slightly quicker for my application which was really just opening and reading whole files into memory. File Size: Ext4 supports file size up to 16 TiB, while Btrfs. This is the number of data disks times the number of blocks per. I've used EX4, XFS, EXT4+LVM and now I'm under BTRFS, and I can tell you, TF2, CSGO, Factorio, KSP, etc, all perform the same under all of them. If not, stick with EXT4, or other more 'classic' solutions. /boot/efi has to be FAT32 (assuming you are using it as the ESP and not just adding partitions extra partitions under /boot to test how robust the boot sequence is). 1 fell slightly short of the Linux file-system performance. It's stable and time-proven. Ext4 focuses on providing a reliable and stable file system with good performance. Its OS comes with only one by default (mostly it’s NTFS, FAT 32, or HFS). Este vídeo muestra el rendimiento de los sistemas de archivos mas usados en un entorno muy parecido al que se encuentra en producción en servidores de archiv. Both. To reserve an external journal with a specified size when you create an XFS file system, specify the -l logdev=device,size=size option to the mkfs. Usable space isn't a big issue but I don't want to lose half with RAID 10. Reasons why I avoided btrfs:Btfs not meant to replace ext4, they are in a different category, ext4 is simple, old and stable while btrfs brings new ideas and goes into very different direction. Januar 2020. Key Btrfs features Perhaps the most important feature is the checksumming of all data. However benchmarks test quite narrow parameters which may not be reflected by running an OS. I have a raid 1 setup on dual 3. 00GHz (8 Cores) MSI C236A WORKSTATION (MS-7998) v1. To organize that data, ZFS uses a flexible tree in which each new system is a child. For example, xfs cannot shrink. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and XFS file-system benchmarks on a speedy WD_BLACK SN850 NVMe solid-state drive. 11. On a single-drive system, performance wise ext4 is what the user wants. The fourth generation File System of the Ext (Extended) file system family. Btrfs和Ext4都是优秀的文件系统，但在选择时需要考虑您的具体需求和使用场景。. 또한 ext3. XFS does not require extensive reading. However, BTRFS had significantly better performance with small files than EXT4. Provides good performance for many enterprise work load, and probably some desktop ones too. With Bcachefs core development being done and the possibility of this file-system being mainlined soon, here are some fresh benchmarks of this file-system compared to Btrfs, EXT4, F2FS, XFS, and ZFS On Linux. Back when Bcachefs debuted in 2015 I ran some initial. Also, reducing the life of my SSD by a month is worth winning an argument from which I get absolutely no benefit. It lived enough, time to move on. Btrfs is the recommended file system to use in most scenarios. Support for large file sizes - The Ext4 supports a single file size of up to 16 TiB ( Tebibytes ) whereas XFS supports a max file size of up to 8 exbibytes. The only benefit of btrfs that I could find was marginally easier setup and the software license. Which is better largely depends on opinion. Recommend. Subvolumes do not have a size, so the Desired. Mar 14, 2012. XFS as a similar featureset filesystem manages around 99. btrfs 可以支援 snapshot, 但 ext4 不行, 如果一開始就採用 ext4, 日後如果要使用 snapshot 功能, 必須將 NAS 的資料備份出來, 重新 format 成 btrfs 格式. Linux 5. 8 snapshot as of last week. Ext2 → Ext3 → Ext4. 여러 가지의 HDD를 장착하여 사용을 하신다면 사진이나 중요한 자료들을 저장하는 드라이브에는. The use of checksums in Btrfs can prevent silent data corruption. I've read and have anecdotally (not scientific and could be affected by other things) experienced Btrfs being slower than ext4. The NTFS support was powered by FUSE. Hi I have used BTRFS for the first time since March 2023 on my internal archives directory. Both btrfs and zfs feel like the worst options considering their overhead. 2. XFS is very well established and changing slowly, and the same can be said for EXT4. Worthy mentions on the functionality front include: Copy-on-write: Btrfs uses copy-on-write to create system snapshots without duplicating data and wasting space. EXT4. Файловая система Ext4 это улучшенная версия Ext3, которая, в свою очередь, не что иное, как переработанная Ext2. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. I have a raid 1 setup on dual 3. When running PostMark, ZFS came out far ahead of the UFS file-systems being more than ten times faster than. From some of the recent Linux kernel patches, it seems some of the most popular Linux file systems, Flash-Friendly File System (F2FS), B-Tree Filesystem (Btrfs), and fourth extended filesystem. 再將資料再回存到 NAS, 這部份會花費很多時間. I think in many ways btrfs is the better filesystem, but I seem to have noticed that it takes longer to copy data than on ext4. Ext4 is the fourth version of the Ext (Extended) File System for Linux and is probably the most well-known file system for Linux out there. both have hidden sharp edges, work differently, and have different design philosophies in terms of the command line tools etc. Regarding boot drives : Use enterprise grade SSDs, do not use low budget commercial grade equipment. 挂载 btrfs 文件系统 6. But unless you intend to use these features, and know how to use them, they are useless. Hi I never worry about it… my latest SSD SanDisk Extreme Pro 240GB has a 10 (limited) year 50GB a day warranty, Have OCZ’s with thousands of hours running btrfs all running fine. When running PostMark, ZFS came out far ahead of the UFS file-systems being more than ten times faster than. XFS is about as mainline as a non-ext filesystem gets under Linux. It supports all. Table of Contents. Note that while these tests are not indicative of real-world performance, we can extrapolate these results and use this as one reason. btrfs has the "btrfs-balance" command. The preferable option depends on your specific needs and priorities. It's the fastest option bar none if you have enough RAM. Overall, except for application launch time, benchmark results show that ZFS is the slowest file system in terms of read and write speed due to its COW operating type, while EXT4 is usually the fastest system. ZFS ain't bad, but this whole btrfs data loss myth needs to stop. So if you have a SSD and care about the wear of that then. For anything with higher capability, XFS tends to be faster. Features of the XFS and ZFS. Rather then using BTRFS, I would use XFS and hope for the best, or using dm-integrity. So it has no barring. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. g. It's not the most cutting-edge file system, but that's good: It means Ext4 is rock-solid and stable. " And it can be much faster than btrfs, especially with lots of smaller files. Both ext4 and XFS should be able to handle it. I'ved tested compress=off/lz4, dedup=on/off and serveral Cache/Log constellations on 256GB SSD. Although both ext4 and XFS are excellent at what they do, neither are suited to some of today’s more complex storage challenges. 但无论如何，各个文件系统都需要存储这三类信息，因为这是内核规定的（见下）。. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4,btrfs is also slower in some benchmarks but I very much doubt thats visible in normal use. Across the three tested RAID modes, EXT4 was performing the worst. Compared to ext4, XFS has unlimited inode allocation, advanced allocation hinting (if you need it) and, in recent version, reflink support (but they need to be explicitly enabled in. Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: FreeBSD ZFS vs. Btrfs provides checksums for data and metadata, ensuring enhanced data integrity. 4 was performing the best for RAID0 and RAID10 modes while with RAID1, XFS was performing the best. Now I may send the snapshots also to an local device (formatted in Btrfs). Já que muitos usuários Linux, que desejam experimentar o novo sistema, vêm do Ext4, faz sentido enumerar alguns pontos que realçam as diferenças entre os dois: O Ext4 ainda é a melhor escolha, no desktop do usuário comum — por ser mais rápido na transferência de arquivos e por ser mais maduro6,861. With not having the time to conduct the usual kernel version vs. 암호화 기능. ZFS is an advanced filesystem and many of its features focus mainly on reliability. In this tutorial, we will check Btrfs against Ext4 filesystem, and seek to understand their functionalities, strengths, and weaknesses. Ext4 focuses on providing a reliable and stable file system with good performance. Through many years of development, it is one of the most stable file systems. 0 hard drive when using EXT4 and XFS.

Using: - A full partition in a single 1TB or 2TB NVMe SSD. Btrfs has been a stable part of the Linux kernel since 2013, and you can reformat your hard drives using the file system today. Things like snapshots, copy-on-write, checksums and more. I'll be going RAID 6. Tính năng sao chép dữ liệu. EXT4 vs. Ext4 file system is an ideal choice. If you have a NAS or Home server, BTRFS or XFS can offer benefits but then you'll have to do some extensive reading first. In most cases that’s EXT4, but for Fedora, OpenSuse and maybe a few others it’s btrfs. First up was the SQLite embedded SQL database library test. 0 X. Latency for both XFS and EXT4. Also, server raid originally md raid5 (4x4TB NAS drives) with XFS had taken all day to build, but creating btrfs-raid10 was seconds. Both Btrfs and Ext4 have their own advantages. , power failure) could be acceptable. The BTRFS RAID is not difficult at all to create or problematic, but up until now, OMV does not support BTRFS RAID creation or management through the webGUI, so you have to use the terminal. EXT4. Each one might work for you based on YOUR needs! Supp. Tweaking the config is easy if you've figured out how to build and load your own kernel. In the past, I have often seen statements that EXT4 is better for gaming than XFS. Use XFS for your array drives and Btrfs for your cache pool. Running AIO-Stress on the Western Digital VelociRaptor was yielding speeds not technically possible for the Serial ATA 3. Btrfs stands for B Tree Filesystem, It is often pronounced as “better-FS” or “butter-FS. This pre-dates xfsprogs 3. It is intended to compete with the modern features of ZFS or Btrfs, and the speed and performance of ext4 or XFS. ZFS also has more options for caches and such things than EXT4. I've set up and used btrfs for years and later zfs for the past few years both professionally and on home servers. BTRFS stands for “B tree File System,” and it is a next-generation filesystem designed specifically for Linux operating systems. The Ext4 file system is a very old file system and it has been used on the Linux operating system for a long, long time. Btrfs vs. EXT4 vs. 2. Btrfs, EXT4, F2FS, and XFS were tested in their out-of-the-box state / default mount options. 0 Intel Skylake 16384MB Samsung SSD 950 PRO 256GB LLVMpipe Realtek ALC1150 Intel Connection Ubuntu 16. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. ZFS likes eating RAM. The mount command for ext4 has the "stripe" option. For BTRFS, the overall throughput is fairly low (~30k tps), while the jitter is somewhat better and worse than for EXT4/XFS at the same time. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. How do the major file systems supported by Linux differ from each other? Compared to Ext4, XFS has a relatively poor performance for single threaded, metadata-intensive workloads. Two subvolumes, root and home, are created from that pool and mounted at / and /home respectively. After a week of testing Btrfs on my laptop, I can conclude that there is a noticeable performance penalty vs Ext4 or XFS. . Btrfs（技术预览）" Collapse section "6. It was later developed for Linux. For a future article will be a look at non-mainlined file-systems,. On the NVMe SSD, the four-thread FS-Mark was the fastest on XFS followed by Btrfs. The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3. Btrfs is newer and more experimental, but offers advanced capabilities like snapshots, checksums, and inline compression. But. Storage Manager Last updated: Apr 18, 2023 Purpose This article compares the different file systems to help you decide which one to choose when creating a. I understand that btrfs have a major problem with Raid, - and that is a problem. If you are running a more stable system like Dabian based Linux EXT4 is a better choice because it's faster file system but not as easy to revert. In this episode of the CyberGizmo I benchmark the 4 filesystems chosen by Phoronix for his testing and use my own workloads to compare and contrast them. It can create, diff and restore snapshots and provides timelined auto-snapping. User quotas for each shared folder. Hi, I think BTRFS is actually faster then ZFS on Linux. 84 nvme drives split up into a small ext4 volume and the rest is btrfs. 0 SSD drive used was a 250GB Samsung 850 PRO solid-state drive connected both. Performance: Ext4 performs better in everyday tasks and is faster for small file writes. Pros: Individual file size: 16GB to 2TB. Now Fedora just needs to implement it properly like openSUSE. kernel. Perhaps btrfs is much better for SSDs, but in oldschool HDDs I. A continuación, os vamos a explicar brevemente las principales características de EXT4 y de Btrfs. could go with btrfs even though it's still in beta and not recommended for production yet. Quota journaling: This avoids the need for lengthy quota consistency checks after a crash. 6. Ext4 se basa en una tecnología más antigua, por lo que carece de las características modernas del sistema de archivos que se encuentran en sistemas como E2FS y BtrFS. for the home lab you can use ext4 it is fast an flexible: grow and shrink are supported. Linux File-systems were tested on NVMe SSD including EXT3, BTRFS, EXT4, XFS, and ZFS from the mainline kernel of Linux 4. Reliable! I used it in Rsync mode as only my backup disk is btrfs, everything else was ext4 or XFS. jkool702. 1. Btrfs supports RAID 0, 1, 10, 5, and 6, while ZFS supports various RAID-Z levels (RAID-Z, RAID-Z2, and RAID-Z3). 其他 ext4 文件系统实用程序 6. But again, there's no real point in going with btrfs if only using two drives. Btrfs is the recommended file system to use in most scenarios. My current setup is /@ for the rootfs, /@home for home dir, works great. Hi there, I‘m thinking of changing my filesystem from ext4 to btrfs, as I have read a lot of positive things about it online. Data Colossi & Data Centers: Ext4 is non-negotiable for handling extensive data transactions. 8. Ability to create large volumes of up to 1 PB 1. ran defragment utility to compress all existing files. 2. Let’s go through the different features of the two filesystems. On the other hand, for Linux/Unix-based devices, it might be a bit of a challenge choosing one among many options. In a few words, I just need a really reliable and fast filesystem for years ahead, with the care of SSD in mind, I need it mostly for gaming, video-audio production, working with a lot of small/medium files (from 100-500Kb to 100-150Gb) sending them. Personally I run btrfs on all my Linux devices, some of them with half-decade old installations of Arch and they've all performed admirably. A maximum partition size of the btrfs file system is 16 exbibytes, as well as maximum file size is 16 exbibytes too. An anonymous reader writes "Phoronix has published Linux filesystem benchmarks comparing XFS, EXT3, EXT4, Btrfs and NILFS2 filesystems. In today's video, we will talk about the 4 Major Linux File Systems. Your gaming performance shouldn't be affected by either, since games are mostly just reads anyways. I converted my ext4 disks (3 x ssd + 1 x hdd) to btrfs, and all was well. Ext4 Filesystem 其實你提到一個重點了. It is the default file system in Red Hat Enterprise Linux 7. It was time to do my quarterly disaster recovery drill, which involves bootstrapping my entire system from scratch using my scripts and backups. Moreover, the ext4 is more beneficial when the. Each of these file systems has its own way of organizing data, merits, and demerits. 其實你提到一個重點了. A Seagate FireCuda 520 PCIe 4. Have snapper to create pre/post BTRFS and LVM snapshots. For a side-by-side feature comparison of the major file systems in SUSE Linux. While RAID 5 and 6 can be compared to RAID Z. 현재 Ext4는 Red Hat Enterprise Linux 6의 기본 파일 시스템으로 단일 파일 및 파일 시스템 모두에서 최대 16 TB 크기 까지 지원합니다. Edit: I managed to save the two NTFS HDDs with chkdsk, but the exFAT drive just didn't wanna play ball. , power failure) could be acceptable. If you omit the size parameter, a journal size based on the size of the file system is used. It's a 64-bit, journaling filesystem that has been built into the Linux. Ext4 has journaling on by default, and new users likely won’t know how to disable it to save read/writes on their SSDs. It's solid and tested and I'm not sure I see any benefit to another file system there. ext4 is not recommended. could go with btrfs even though it's still in beta and not recommended for production yet. Windows users don’t have much of a choice regarding a file system. ext3 is the most common format. BtrFS is still very experimental and is not recommended for a production server or desktop environment. EXT4 had the best speed at 58MB/s while Btrfs came in slightly behind that at 52MB/s and then ZFS came in at 46MB/s. 1 million iops for ext4, right in line with the spec of the drive times 2,. I think in many ways btrfs is the better filesystem, but I seem to have noticed that it takes longer to copy data than on ext4. SSD Disk Observations. Written by Michael Larabel in Storage on 20 January 2018. However, when we review EXT4 vs BTRFS, here’s the downside: BTRFS has disk and volume management built-in, while EXT4 is a “pure filesystem”. With not having the time to conduct the usual kernel version vs. ZFS brings robustness and stability, while it avoids the corruption of large files. The benchmark results of three most common file systems under Linux environment were given in this paper. Btrfs has been a stable part of the Linux kernel since 2013, and you can reformat your hard drives using the file system today. This is because BTRFS is optimized for handling small files, while EXT4 can struggle with multiple small files due to its delayed allocation. Not only does both file systems feature a more robust data assurances then XFS (the mature fsck for Ext4 and checksums and data. Btrfs is not a successor to the default Ext4 file system used in most Linux distributions, but it can be expected to replace Ext4 in the future. Especially things that cause lots of file-internal fragementation like databases. OMV supports btrfs but you still have to scrub etc yourself from the command line. BTRFS bietet, mal abgesehen von der Möglichkeit einer Inline Deduplizierung, beinahe alle Features von ZFS. Btrfs was developed specifically to facilitate quick administration and maintenance. 3 which makes XFS v5 the default and all the benefits it brings. XFS vs. Btrfs is a bit slower with writes because of its Copy-on-write nature, but just as fast when it comes to reads. BTRFS also had somewhat higher latency than EXT4, meaning that it took longer for files to be accessed on the file system. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. I use ext4 everywhere. Ext4 (Extended File System) Btrfs ( B-tree File System) Lợi ích khi chạy File System Btrfs trên NAS Synology. Here are a few other differences: Features: Btrfs has more advanced features, such as snapshots, data integrity checks, and built-in RAID support.

Between EXT4 and XFS which file system is better when an application uses multiple threads to read/write large amount of small files on a SSD. Data integrity protection. Each of these file systems has its own way of organizing data, merits, and demerits. Increased Performance of ext4 vs. Its OS comes with only one by default (mostly it’s NTFS, FAT 32, or HFS). To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. Both Btrfs and ZFS offer built-in RAID support, but their implementations differ. The reason that Ext4 is often recommended is that it is the most used and trusted filesystem out there on Linux today. Each of the five file-systems were tested on the same NVM Express SSD from the Linux 4. However benchmarks test quite narrow parameters which may not be reflected by running an OS. This is fundamental in determining the file system’s capacity. 38. The btrfs and zfs storage drivers allow for advanced options, such as creating "snapshots", but require more maintenance and setup. Be sure to change the /etc/fstab to reflect the change ( type to btrfs and fs_passno [the last field] to 0 as Btrfs does not do a file system check on boot). I know the latest versions do not setup /home in a separate partition anymore but as a btrfs subvolume instead. Btrfs vs. We would like to show you a description here but the site won’t allow us. (當然另一種做法是新增硬碟, 另外格式化為 btrfs. Btrfs is expected to offer better. 10. I'd stick with safer file systems like XFS, JFS, EXT4, or imported ZFSOnLinux. The XFS one on the other hand take around 11-13 hours!With Bcachefs on its trek towards the mainline Linux kernel, this week I conducted some benchmarks using the very latest Bcachefs file-system code and compared its performance to the mainline Btrfs, EXT4, F2FS, and XFS file-system competitors on both rotating and solid-state storage. I was using NTFS due to compatibility. 8 snapshot as of last week. Ext4文件系统是Ext3的继承者，是Linux下的主流文件系统。经过多年的发展，它是目前最稳定的文件系统之一。但是，老实说，与其他Linux文件系统相比，它并不是最好的Linux文件系统。 在XFS vs Ext4方面，XFS在以下几个方面优于Ext4： I've seen benchmarks (eg: this one) that put btrfs considerably slower than ext4. Btrfs El sistema de archivos Btrfs nació como sucesor natural de EXT4, su objetivo es sustituirlo eliminando el mayor número de sus limitaciones, sobre todo lo referido al tamaño. Thanks again! Unless you're doing something crazy, ext4 or btrfs would both be fine. The arguments about ext4 vs NTFS have been raging online for decades now.

It was also 164% faster in post-snapshot reads and 17% faster in post-snapshot writes. BTRFS has better backup capabilities, but is considered less stable, despite it working for me just fine with my testing of it. Ext4 file system is the successor to Ext3, and the mainstream file system under Linux. With btrfs I got 130-160MB. Btrfs vs. Multimedia Sanctuaries: With large files as daily bread, ext4 is indispensable. The btrfs backup multi-disk arrangement, of different disk sizes in single mode was for me a trial of btrfs. Hey Guys! Welcome to XPSTECH. BTRFS hatte auch etwas höhere Latenz als EXT4, was bedeutet, dass es länger dauerte, bis Dateien auf dem Dateisystem zugegriffen werden konnten. After a week of testing Btrfs on my laptop, I can conclude that there is a noticeable performance penalty vs Ext4 or XFS. In this article, we will have a look at deeper details at these file systems comparatively including EXT4 vs XFS, EXT4 vs EXT3, BTRFS vs EXT4 as well as ZFS vs EXT4. Ext4 fs can read and write to Ext2 or Ext3 file systems, but the Ext4 it is not compatible with Ext2 and Ext3 drivers. Windows users don’t have much of a choice regarding a file system. Theodore Ts’o, a maintainer for Ext3 and later, Ext4, has stated that he sees Btrfs as a better way forward than continuing to rely on the ext* technology. A daily snapshot of Ubuntu 19. In the end I use ext4 as trustworthy frontend, and btrfs as a unreliable backup. 드라이브 압축. Both Btrfs and Ext4 have their own advantages. If you use Debian, Ubuntu, or Fedora Workstation, the installer defaults to ext4. For single disks over 4T, I would consider xfs over zfs or ext4. F2FS vs. Btrfs（技术预览）" 6. Ext4 vs ext3. BTRFS solves all the problems I had so far: supports online resizing - both extending and shrinking. ext4 can claim historical stability, while the consumer advantage of btrfs is snapshots (the ease of subvolumes is nice too, rather than having to partition). #6. It you have huge hard drives, BTRFS supports up to 16 times larger size than 1 EXT4 partition. For example btrfs supports transparent file compression. Because of that, the Ext4 file system is very stable. OpenSUSE hiện sử dụng btrfs làm tùy chọn mặc định cho phân vùng /root, nơi đặt hệ điều hành. What we mean is that we need something like resize2fs (ext4) for enlarge or shrunk on the fly, and not required to use another filesystem to store the dump for the resizing. Granted, i just use the automatic partition creater at setup, so it still uses ext4 for the /boot and /boot/efi partitions. And ext3. Backups and CoW, are why I use btrfs. My recommendation of that list would be XFS. Linux File System Comparison: XFS vs. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. In some areas Btrfs was showing great improvements in performance, especially for the RAID setup, but it still lacked in some other areas. Linux EXT4/Btrfs RAID With Twenty SSDs Storage :. ZFS is great but heavy/complex, and lack of block pointer rewrite can be painful. Out of curiosity I have tried BTRFS (still unstable so I can't really expect to be able to use it) and noticed that the read speed is about 150% of ext4 - while write speed is comparable.
