Testing – Access Time & Random Read

XFX Revo64 RAID 3 Controller Review - Storage 44

Looking at the access time results above, you can see that the Revo64 appears to be the slowest of all drive configurations even against single SATA-1 and SATA-2 drives. I suspect these results appear this way because of the latency caused by the PCI bus.

It’s interesting to see RAID 3 and RAID 0 on the Revo64 performing so closely. Given the dangers of a Striped array, adding a 3rd disk for the added data integrity of RAID 3 while maintaining quick performance is alluring.

In random read performance, it’s not surprising the Revo64 ends up looking pretty poor in this test. If you were expecting some form of decent performance in RAID 3 mode, you can forget about it. Small random reads/writes is not RAID 3’s strong trait since each block is read byte by byte across the array (high overhead).
