Linux 3.14 Kernel File-System SSD Benchmarks
After last week delivering HDD file-system benchmarks on the in-development Linux 3.14 kernel, here are benchmarks of the Btrfs, EXT4, and F2FS file-systems from a solid-state drive.
The ASUS Zenbook Prime Intel ultrabook with Core i7 Ivy Bridge CPU and dual SSDs was called into action for this SSD benchmarking of file-systems on Linux 3.14. This ultrabook has dual 128GB SanDisk SD5SF212 solid-state drives: one disk was used for the Ubuntu 14.04 x86_64 Linux installation while the other SSD was used for carrying out these file-system benchmarks. The Linux 3.12, 3.13, and 3.14 Git kernels were tested with the Btrfs, EXT4, and F2FS file-systems.
Each time the secondary SSD was freshly formatted between kernels and file-systems. All of this disk benchmarking was done with each file-system's default mount options. The benchmarking process was fully handled via the Phoronix Test Suite for reproducibility, accuracy, and automation of the tests. This testing is very similar to last week's 3.14 file-system testing but with a solid-state drive so let's jump straight to the results.
