- Abstract
- In this paper, we measure the I/O performance of five filesystems-EXT4, XFS, BTRFS, NILFS2, and F2FS, with five storage configurations-single SSD, RAID 0, RAID 1, RAID 10, and RAID 5. We show that F2FS on RAID 0 and RAID 5 with eight SSDs outperforms EXT4 by 5 times and 50 times, respectively. We also make a case that RAID controller can be a significant bottleneck in building a RAID system with high speed SSDs.
