With 8GB writes using IOzone and the Phoronix Test Suite, XFS delivered the best performance using Intel's flagship SSD series. However, creeping up behind XFS was the EXT4 file-systme while EXT3, ReiserFS, and JFS were all well behind these two.
Like the 4GB read tests, when the read size was increased to 8GB, the new EXT4 file-system had remained in front. EXT4 had an average read speed of 189MB/s while JFS popped into second at 181MB/s and EXT3 at 180MB/s. XFS had fallen to 168MB/s and ReiserFS was in last at 159MB/s.
In our last test we tested the Intel IOMeter File Server Access Pattern using the Flexible IO Tester. With this test, ReiserFS performed the best followed by EXT3 and then EXT4. JFS was positioned in last while XFS was in fourth. The results were quite close between ReiserFS, EXT3, and EXT4.
EXT4 and XFS were the two file-systems that had performed particularly well on the Intel X25-E Extreme SSD. However, as we had used just an Intel Core 2 Duo P8600 for this testing and provided just a brief look at the performance, we will not be drawing any definitive conclusions within this article. What will be interesting for solid-state drives in the coming months, however, will be Btrfs. We hope to be delivering Btrfs Linux benchmarks in the very near future, so stay tuned.
