The PCMark 10 Data Drive Benchmark has been designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.
The Data Drive Benchmark provides an overall score (which we aren't showing) plus values for average bandwidth and access time (which we are).
Unsurprisingly, RAID 0 over 10Gbit Ethernet wins this benchmark, and RAID 5 (which also uses some parallel reading and writing) comes a close second. RAID 10 is rather slow here. Over 2.5Gbit Ethernet, the more complex RAID 5 and 6 face a bigger penalty from the slower wire speed.
RAID 0 and RAID 5 offer the fastest file access time over 10Gbit Ethernet, with RAID 10 the slowest. The 2.5Gbit Ethernet connection noticeably slows down access, with RAID 5 and particularly RAID 6 considerably behind RAID 0 and RAID 10.
