Phoronix: File-System Benchmarks On The Intel X25-E SSD

Late last month we looked at the Intel X25-E Extreme SSD on Linux. We ran this high-performance solid-state drive within a System76 Serval Notebook and compared its performance to a Seagate Momentus 7200.2 SATA HDD. During that testing we were just using the default EXT3 file-system, but now we have taken the Intel X25-E SSD for another spin as we looked at its performance when using the ReiserFS, JFS, XFS, EXT3, and EXT4 file-systems.

I'd love to see reiser4 with cryptcompress on when your pulling in btrfs testing.
A basic mkfs.reiser4 -o create=ccreg40,compress=lzo1 for example.

It'll up the cpu usage, but it'd be interesting to see how much faster reiser4 is when seek times arn't involved.

Is it possible that files for compilation tests are all in cache already, so Kernel never touch file system code anyway, hence same results across the board? I don't see in TFA any measures taken for clearing cache between tests.

I wonder what could be the performance of the file systems specialized for solid state drives (JFFS2, YAFFS2, LogFS, UBIFS...). Any reason for not including them in this benchmark ?

Where's Reiser4?

Where's Reiser4?

Far away from Linux kernel...

Far away from Linux kernel...

... deeply burried somewhere in california.

Because they need direct access to the flash memory (via MTD), while SSD expose themselves as normal HDs (i.e. block devices).

Hey Michael, can you do an article about ATI Stream Software Development Kit (SDK)since it's the amd counterpart againts NVIDIA Cuda?

... deeply burried somewhere in california.

if both is true - so what ?

it's still by far the best filesystem out there (btrfs doesn't count yet)

that criteria that a filesystem's included in the linux-kernel doesn't mean that it's superior compared to other filesystems

also the benchmarks are not fair, jfs doesn't support barriers from what I know

and ext3, ... have no support for extents / delayed allocation, ...

so when comparing those filesystems the differences have to be pointed out

also: WHERE ON EARTH IS SPACE EFFICIENCY / SPACE USAGE compared ?

especially with the early SSDs space is pretty precious and if you can store double compared with another filesystem it's worth gold ...

besides all of this ranting:


thanks very much for these benchmarks, they at least give an superficial possibility to compare the filesystems to each other
