HDTune Pro 3.0 x32 Storage Benchmark
Higher Transfer Rates, Lower CPU Utilization and Access Times are Better

HDTune showcases the Barracuda ES.2 in a very positive manner. In these tests, we see a single Barracuda ES.2 SAS drive delivering sustained transfer rates of 87 MB/s and a burst rate of 116 MB/s. When paired together in a RAID setup, these increase to 145 MB/s and 155 MB/s, surprisingly substantial gains.

The Barracuda ES.2 SAS drive still suffers from somewhat high access/seek times at about 12ms for a single drive, but that’s to be expected from a 7,200 RPM drive from Seagate. CPU utilization was low in a single drive setup, although we see 5% CPU utilization when these SAS drives are paired up in a RAID-0 setup, which is a bit higher than we would have liked. We’ll likely chalk this up to the software-based Promise SAS RAID controller card.
