CrystalDiskMark is a new synthetic test we've started looking at that tests both sequential as well as random small and large file transfers. It does a nice job of providing a quick look at best and worst case scenarios with SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.
Once again we've provided some tests on various Intel X25-M SSD configurations, OCZ's Z-Drive, and a Fusion-io ioDrive just for reference as a baseline.
|ATTO and CrystalDiskMark Benchmarks |
|Synthetic Small and Large File Transfer Tests|
Intel X-25M G2 - 160GB Single SSD
Intel X25-M G1 X4 RAID 0 - 320GB
OCZ Z-Drive m84 256GB
Fusion-io ioDrive 160GB SLC
ioXtreme Pro 80GB
2 x ioXtreme - RAID 0 - 160GB
Once again, we observed that both the ioXtreme cards perform virtually identical, offering in excess of 750MB/sec read throughput and 300MB/sec of write throughput for sequential transfers and random transfers at 512K. The 4K random transfer test of course takes all the SSDs we tested to their knees. Fusion-io's hugely expensive ioDrive enterprise solution offers the best single drive performance of the bunch however, under all conditions. Finally, this time we were able to run the ioXtremes cards in RAID 0 and the numbers speak for themselves - a peak of 1348MB/sec read and 586MB/sec write bandwidth is certainly something to covet, at least from a geek's perspective.
