Linux 4.20 I/O Scheduler Benchmarks On NVMe SSD Storage

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.

Linux RAID Benchmarks With EXT4 + XFS Across Four Samsung NVMe SSDs

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.

Benchmarks Of Btrfs RAID On Four Samsung 970 EVO NVMe SSDs

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.

EXT4 LUKS dm-crypt, eCryptfs, Fscrypt Encryption Benchmarks For A USB 3.0 HDD

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.

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.
