See the overview of the OWC Mercury Elite Pro Dual.
The unit was tested in a RAID-0 stripe configuration (double capacity, double speed vs a single drive metric). Total capacity 6TB as 3 X 2TB.
Peformance results
Thunderbolt: 294, 296 write/read MB/sec
Performance is as good as can be expected: hard drives slow down across the capacity by about πD. The spike at the end is a typical behavior and should be ignored.
Even when completely full, the striped configuration still delivers performance as good or better than a single drive when empty.
This level of sustained transfer speed performance can handle most computing tasks very well. Having high data rates for this high capacity is a welcome performance enhancement.
Testing performed with the DiskTester fill-volume command. DiskTester is part of diglloydTools.
