A few days ago I set out to try out BCache on the Linux 4.1 kernel now that this caching feature has matured in the mainline Linux kernel for a while. BCache serves as a cache to the Linux kernel's block layer whereby a solid-state drive (or other faster drive) can serve as a cache to a larger-capacity, traditional rotating hard drive.

Earlier this month I posted some Btrfs RAID 0/1 benchmarks on Linux 4.1 as a prelude to some larger Btrfs RAID benchmarks. Today the rest of those results are available with using five disks and testing Btrfs on this newest version of the Linux kernel while testing the RAID 0, 1, 5, 6, and 10 levels.

With the Linux 4.1 kernel coming together nicely I've begun my testing (separate from all the fully-automated Git testing done each day via the LinuxBenchmarking.com systems) of this new kernel under a variety of different workloads, stressing different systems, and focusing on the changes in the major subsystems. One of the systems this week has been running some fresh Btrfs RAID Linux file-system benchmarks. From an eight-disk server I've started this Btrfs RAID testing as some fresh numbers since my Btrfs RAID tests from a few months back on an older server.

The latest solid-state drive being added to one of our Linux test farm systems is the Samsung 850 EVO. Prior to commissioning this drive in one of the systems, I ran some benchmarks against a few other solid-state drives while testing with the EXT4 file-system on Ubuntu Linux.

For those looking for a very economically priced SSD that's still reliable and from a well known vendor, the OCZ ARC 100 series might be the most tempting drive line-up yet. With the OCZ ARC 100 series, a 256GB SSD costs only $90 USD or a 480GB SSD for $197. Though in this article the OCZ ARC 100 120GB SSD is being tested and it retails for less than $70 USD.

It's been ten years since last testing any Transcend products, back in the days of DDR2 memory and 1GB flash drives. However, that changed when recently picking up a Transcend SSD370 256GB solid-state drive.

The latest solid-state drive being tested at Phoronix is the 120GB OCZ Vector 150. This solid-state drive is quite affordable but has been reviewed favorably by Windows users, so we figured we'd see how well it works when adding it to one of the constantly-running Linux benchmark systems.

In my recent articles doing RAID 0/1/5/6/10 benchmarking on Btrfs/EXT4/XFS/F2FS, I've been using four 120GB Intel 530 Series SSDs. I went with these four solid-state drives for getting a deal on them and having been pleased with numerous Intel SSDs I've used in the past and still running in a few Linux test systems, but how does the Intel 530 Series SSD on Linux compare to other modern solid-state drives? If you've been eyeing the SSDSC2BW12 SSDs, here's some fresh single-drive SSD benchmarks using Btrfs compared to drives from OCZ, Corsair, and Samsung.
