Intel SSD 760p 256GB NVMe SSD For $99 USD On Linux

If the extremely fast Intel Optane SSD 900p is out of your budget with its 3D XPoint memory, this week Intel rolled out the SSD 760p series with 64-layer TLC 3D NAND memory. For less than $100 USD you can get the 256GB capacity Intel 760p SSD, which is what we are benchmarking today under Ubuntu Linux.

ADATA XPG SX6000: Benchmarking A ~$50 USD 128GB NVMe SSD On Linux

While solid-state drives have generally been quite reliable in recent years and even with all the benchmarking I put them through have had less than a handful fail out of dozens, whenever there's a bargain on NVMe SSDs, it's hard to resist. The speed of NVMe SSDs has generally been great and while it's not a key focus on Phoronix (and thus generally not receiving review samples of them), I upgrade some of the server room test systems when finding a deal. The latest is trying an ADATA XPG SX6000 NVMe SSD I managed to get for $49.99 USD.

4 x SSD Btrfs/EXT4 RAID Tests On Linux 4.15

Using the high-end SilverStone TS421S 4-disk SATA drive enclosure, I've been carrying out a number of Btrfs and EXT4 file-system multi-disk benchmarks over the past week. Here are the latest numbers for how Btrfs' native RAID capabilities are running up against EXT4 when using MDADM "soft" RAID.

Linux File-System Benchmarks On The Intel Optane 900P SSD

Earlier this week I presented out initial Linux benchmarks of the Intel Optane 900P SSD with this 3D XPoint memory U.2 solid-state drive delivering incredible performance figures. Those tests were done with EXT4 while in this article are more tests with other mainline Linux file-systems and also testing some of the different mount options.

Btrfs Zstd Compression Benchmarks On Linux 4.14

Of the many new features in Linux 4.14, one of the prominent additions is initial support for Zstd compression that is initially wired in for transparent file-system compression with SquashFS and Btrfs. Here are some benchmarks of Zstd Btrfs compression compared to the existing LZO and Zlib compression mount options.

HDD/SSD Performance With MDADM RAID, BCache On Linux 4.14

It's been one year since last testing BCache as a means in the Linux kernel's block layer to allow an SSD to serve as a cache for a larger but slower rotational hard drive. So I have carried out some fresh benchmarks using the Linux 4.14 Git kernel to provide not only fresh benchmarks of BCache but also MDADM SSD RAID on Linux and some other fresh SSD/HDD benchmarks.

Linux RAID Performance On NVMe M.2 SSDs

For boosting the I/O performance of the AMD EPYC 7601 Tyan server I decided to play around with a Linux RAID setup this weekend using two NVMe M.2 SSDs. This is our first time running some Linux RAID benchmarks of NVMe M.2 SSDs and for this comparison were tests of EXT4 and F2FS with MDADM soft RAID as well as with Btrfs using its built-in native RAID capabilities for some interesting weekend benchmarks.

Intel 545s 512GB SSD Benchmark On Linux

Intel announced their 545s series SSD last month and it's been making plenty of rounds on Windows. Curious about the Linux performance, I picked up the Intel 545s 512GB SATA 3.0 SSD for benchmarking on Linux.

Linux 4.12 I/O Scheduler Tests With A HDD & SSD

Earlier in the Linux 4.12 cycle I delivered a number of I/O scheduler benchmarks from a solid-state drive while for this article are some fresh I/O scheduler tests using a slower SSD as well as a conventional HDD. Schedulers tested were CFQ, Noop, deadline, MQ None, MQ Kyber, MQ BFQ, and MQ Deadline.

ADATA SU800 128GB SSD On Linux

Needing to replace a failed hard drive in one of our server room benchmark systems, I decided to try out the ADATA SU800 as something new. It's an affordable SATA 3.0 SSD and in not trying out an ADATA SSD in a while, I decided to purchase this one and run some benchmarks on it prior to commissioning it to its new home.

Corsair Force MP500 240GB M.2 SSD On Linux

I picked up a Corsair Force MP500 NVMe M.2 solid-state drive for one of the new test systems in the Phoronix lab and so I ran some benchmarks on this high-performance drive compared to a few other SSDs.

Linux 4.12 I/O Scheduler Benchmarks: BFQ, Kyber, Etc

Among the many new features for Linux 4.12 are two new I/O schedulers in mainline: the long-standing BFQ (Budget Fair Queueing) and Kyber, a new I/O scheduler developed at Facebook. Here are some initial benchmarks of these I/O schedulers on the Linux Git code as of this past week.

Btrfs vs. F2FS Multi-SSD Performance On Linux 4.11

Last week I posted benchmarks showing off F2FS performance with its multi-drive feature that isn't formal RAID but can still yield better I/O performance. For additional context, here are some results on that same system and with the Linux 4.11 kernel when using Btrfs with its native RAID capabilities.

Testing F2FS With Its Multi-Drive Capabilities

Late last year F2FS picked up multiple device support for this Flash-Friendly File-System. This F2FS multi-drive capability isn't native RAID support like Btrfs but just allows a single F2FS file-system to span multiple devices. But it's more than that in that block allocation and the garbage collection policy is modified to boost I/O performance by taking advantage of the multiple SSD/flash devices.

EXT4 / F2FS / Btrfs / XFS On Early Linux 4.10 Kernel

Given all the changes with the Linux 4.10 kernel, including a fair amount of work on file-systems and block / I/O code, here are some fresh benchmarks of the EXT4, F2FS, Btrfs, and XFS file-systems atop a solid-state drive when comparing the early post-RC1 Linux 4.10 kernel benchmarks to that of the 4.6/4.7/4.8/4.9 stable kernels.
