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.

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.

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.

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.

EXT4, Btrfs, XFS & NILFS2 HDD File-System Tests On Linux 4.8

Up until running the tests for today's article, I can't remember the last time I touched a hard drive... It's been many months ago at least. Nearly all of our tests at Phoronix are from solid state storage, but I decided to pick up a new HDD for running some Linux file-system tests on a conventional hard drive for those not having an SSD.

OCZ Trion 150 Budget SSD On Linux

The Trion 150 has been generating a fair amount of buzz since its release back in January as being a nice budget solid-state drive ideal for first-time SSD buyers. The Trion 150 is a true budget SSD with the 480GB SATA 3.0 drive retailing for just $140 USD, or about 30 cents per GB. Tests and results of the OCZ Trion 150 under Windows have been rather favorable so I figured it would be interesting to test out this drive under Ubuntu Linux.
