Last month Crucial introduced their P2 NVMe SSD series as their new low-cost successor to their prior P1 series. The Crucial P2 500GB NVMe solid-state drive retails for $60~65 USD which offers good value and yields better performance than their prior low-cost P1 SSDs.

While some Linux distributions are still using MQ-Deadline or Kyber by default for NVMe SSD storage, using no I/O scheduler still tends to perform the best overall for this speedy storage medium.

Recently a Phoronix reader inquired about seeing some fresh hard drive RAID benchmarks on the current kernel release and using Btrfs / EXT4 / XFS. While we don't often look at HDD RAID performance these days compared to speedier SSD testing, since the reader was a generous Phoronix Premium member I was happy to oblige to his test request. Here is a look at the Linux 5.4 HDD RAID performance per his request with Btrfs, EXT4, and XFS while using consumer HDDs and an AMD Ryzen APU setup that could work out for a NAS type low-power system for anyone else that may be interested.

When it comes to PCIe 4.0 NVMe SSDs, the drives we have been using are the Corsair Force MP600 that have been working out great for pairing with the newest AMD Ryzen systems. But a Black Friday deal had the Sabrent 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 SSD on sale, so I decided to pick one up to see how it was performing on Ubuntu Linux. Here are benchmarks of the Sabrent Gen4 NVMe SSD, which in the 1TB capacity can be found for $150~170 USD.

One of the first PCIe Gen 4 NVMe SSDs to market has been the Corsair Force MP600. AMD included the Corsair MP600 2TB NVMe PCIe4 SSD with their Ryzen 3000 reviewer's kit and for those interested in this speedy solid-state storage here are some benchmarks compared to various other storage devices on Ubuntu Linux.

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.

This round of benchmarking fun consisted of packing two Intel Optane 900p high-performance NVMe solid-state drives into a system for a fresh round of RAID Linux benchmarking atop the in-development Linux 5.2 kernel plus providing a fresh look at the ZFS On Linux 0.8.1 performance.

With falling memory prices, there's multiple solid-state drives available for around the $30 USD price point that offer 240~256GB capacities. Here are benchmarks of five such drives, four of which are SATA 3.0 SSDs and even one NVMe SSD. There are also comparison points to more premium SSD products.

With iX Systems having released new images of FreeBSD reworked with their ZFS On Linux code that is in development to ultimately replace their existing FreeBSD ZFS support derived from the code originally found in the Illumos source tree, here are some fresh benchmarks looking at the FreeBSD 12 performance of ZFS vs. ZoL vs. UFS and compared to Ubuntu Linux on the same system with EXT4 and ZFS.

In the past few months a number of M.2 NVMe SSD to USB adapters have been appearing on the market. Curious about the performance potential on Linux of an NVMe SSD drive attached to a USB 3.1 connection, I recently picked up a QNINE NVMe solid-state drive enclosure for benchmarking.

Announced at the end of January was the Samsung 970 EVO Plus as the first consumer-grade solid-state drive with 96-layer 3D NAND memory. The Samsung 970 EVO NVMe SSDs are now shipping and in this review are the first Linux benchmarks of these new SSDs in the form of the Samsung 970 EVO Plus 500GB MZ-V7S500B/AM compared to several other SSDs on Linux.

With TrueOS offering daily snapshots built against the "ZFS on FreeBSD" code derived from OpenZFS / ZFS on Linux, I decided to run some benchmarks to see how the performance compares to that of FreeBSD 12.0 with its ZFS file-system support, DragonFlyBSD 5.2.1 with its HAMMER2 file-system alternative, and then Linux with ZFS/ZoL and other file-system options.

With all of the major file-systems seeing clean-up work during the Linux 4.21 merge window (now known as Linux 5.0 and particularly with F2FS seeing fixes as a result of it being picked up by Google for support on Pixel devices, I was curious to see how the current popular mainline file-system choices compare for performance. Btrfs, EXT4, F2FS, and XFS were tested on a SATA 3.0 solid-state drive, USB SSD, and an NVMe SSD.

After being announced a few weeks back, the Samsung 860 QVO series is beginning to ship as a new, lower-cost SATA 3.0 SSD offering. The Samsung 860 QVO series offers four bit per cell flash memory to usher in a new era of lower-cost solid-state storage with the now-shipping 1TB model costing just $150 USD while the 2TB version coming soon at $300 USD and $600 USD for a 4TB edition.

With FreeBSD 12.0 running great on the Dell PowerEdge R7425 server with dual AMD EPYC 7601 processors, I couldn't resist using the twenty Samsung SSDs in that 2U server for running some fresh FreeBSD ZFS RAID benchmarks as well as some reference figures from Ubuntu Linux with the native Btrfs RAID capabilities and then using EXT4 atop MD-RAID.

Complementing the recent Linux 4.19 I/O scheduler benchmarks using SATA 3.0 SSD storage, here are some benchmarks when using the current Linux 4.20 development kernel and also using faster NVMe solid-state storage for benchmarking. Most Linux distributions default to no I/O scheduler in the case of NVMe SSDs, but for your viewing pleasure today is a look at the performance against MQ Deadline, Kyber, and BFQ.

Last week Corsair announced the Force Series MP510 M.2 PCIe NVMe solid-state drives as the company's fastest SSDs to date. While being Corsair's latest and fastest NVMe SSDs, the pricing is competitive with the 240GB model starting out at $70 USD, 480GB for $130 USD, $239 for 960GB, or $475 for a 1920GB version.

Last week I offered a look at the Btrfs RAID performance on 4 x Samsung 970 EVO NVMe SSDs housed within the interesting MSI XPANDER-AERO. In this article are some EXT4 and XFS file-system benchmark results on the four-drive SSD RAID array by making use of the Linux MD RAID infrastructure compared to the previous Btrfs native-RAID benchmarks. Tests were done on the Linux 4.18 kernel to provide the latest stable look at the XFS/EXT4 MD RAID performance with these four powerful Samsung 970 EVO 250GB NVMe solid-state drives.

With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs.

If you have held off on switching over to NVMe solid-state storage due to the associated costs, times are certainly changing. This week Intel introduced their 660p SSD series that yields 512GB of NVMe storage for $99 USD or 1TB for $200 USD.

Back in June Toshiba introduced the RC100 NVMe solid-state drive as a new low-end offering. The RC100 is now a bit blindsided by Intel's just-launched 660p SSD that delivers incredible storage capacities per dollar, and I'll have some Intel 660p Linux benchmarks in a few days, but for those curious about the RC100 here are some Ubuntu Linux benchmark results for this low-cost NVMe SSD.

It's been about three years since last carrying out any file-system performance benchmarks of Reiser4, but being curious how it stacks up against the current state of today's mainline Linux file-systems, here are some fresh performance tests of Reiser4 using the Linux 4.17 kernel. The Reiser4 performance was compared to Reiserfs, EXT4, Btrfs, XFS, and F2FS.

A few weeks back I posted benchmarks of EXT4 fscrypt vs. eCryptfs vs. LUKS dm-crypt benchmarks for showing the EXT4 file-system performance encryption performance for these kernel-based approaches. That testing was done with a SATA 3.0 SSD while in this article is a look at the performance in another popular choice: if using a USB 3.0 external enclosure with a hard drive.

Given the recent advancements of the EXT4 file-system with its native file-system encryption support provided by the fscrypt framework, here are benchmarks comparing the performance of an EXT4 file-system with no encryption, fscrypt-based encryption, eCryptfs-based encryption, and a LUKS dm-crypt encrypted volume.

Last month Samsung introduced the 970 Series solid-state drives with the mainstream 970 EVO models and 970 PRO models for professionals/enthusiasts. The 970 Series moves to a 64-layer flash and uses a five-core Phoenix controller. For those curious about the Samsung 970 EVO performance under Linux, I have carried out some quick benchmarks to show off its potential under Ubuntu.

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.

With the Linux 4.17 kernel soon to be released, I've been running some fresh file-system and I/O scheduler tests -- among other benchmarks -- of this late stage kernel code. For your viewing pleasure today are tests of a high performance Intel Optane 900p NVMe SSD with different I/O scheduler options available with Linux 4.17.

With this week's release of DragonFlyBSD 5.2 this popular BSD operating system is promoting its own HAMMER2 file-system as stable. As a result, here are a few fresh benchmarks of HAMMER vs. HAMMER2 on DragonFlyBSD 5.2 while more tests are forthcoming.

Last month Intel launched the Optane SSD 800P series as a step below the ultra-fast Optane 900P solid-state drives but still a big step ahead of other SSD options like the Intel 760p series. Here are our first Linux performance benchmarks of the Optane 800p series with testing the 118GB SSDPEK1W120GA 800p SSD on Ubuntu.

Here are our latest Linux RAID benchmarks using the very new Linux 4.16 kernel while using two high-end Samsung 960 EVO 500GB NVMe solid-state drives with Ubuntu 18.04 LTS. Using MDADM Linux soft RAID were EXT4, F2FS, and XFS while Btrfs RAID0/RAID1 was also tested using that file-system's integrated/native RAID capabilities.
