HD Tach
We tested HD Tach with the benchmark's full variable zone size setting.

Super Talent claims 60MB/s read and 40MB/s write speeds for the SATA25, and they're not being overly optimistic. The SATA25 just eclipses those numbers in HD Tach's sustained read and write speed tests, in both cases leaving 7,200-RPM mobile drives behind. Again, we see the SATA25 simply outclassing Super Talent's previous generation SSD.

Without a fast DRAM cache, the SATA25 doesn't have a chance in HD Tach's burst speed test. At least the drive's burst performance is more than four times quicker than that of the IDE Flash.

Random access times are where solid-state drives really shine, and this synthetic test shows just how brightly. The SATA25 seeks in just 0.4 milliseconds—20 times faster than Western Digital's fastest Raptor and even a little quicker than the IDE Flash.

CPU utilization results are within HD Tach's +/- 2% margin of error for this test.
