We got our hands on four SAS 6 Gb/s RAID controllers from Adaptec, Areca, HighPoint, and LSI and ran them through RAID 0, 5, 6, and 10 workloads to test their mettle. Does your system need eight more ports of connectivity? We can answer that!

Benchmark Results: Data Throughput In RAID 0, 5, And 5 Degraded

RAID 0

The LSI MegaRAID 9265 clearly wins the RAID 0 benchmark. Adaptec's RAID 6805 cannot keep up.

RAID 5

The cacheless HighPoint RocketRAID 2720SGL handles sequential RAID 5 operations well, leaving the field and closely followed by the Areca ARC-1880i. Adaptec's RAID 6805 and LSI's MegaRAID 9265-8i seem to run out of steam during this test.
