To get an idea of how the Transcend TS32G fares against a standard 2.5" drive, I compared HD Tune results from a Seagate Momentus 7200.1 2.5" 100GB SATA 150 with a claimed sustained throughput of 45.8 MB/s.

While the ST910021AS average transfer rate falls a bit shy of the claimed speed, the peak is actually a little higher. The graph shows that as the drive heads move towards the inner sectors of the spindle the speed begins to drop off. The result is just under 40MB/s average and over 15ms access time.

The TS32G SSD drive average speed is much less, but maintains an almost constant 24-25MB/s throughout the test. Also the access time is phenomenal, less than 3ms. Note that there was zero CPU utilization recorded, something I've never seen before with a traditional hard drive.

HD Tach shows similar results, with a nearly identical 25.2MB/s average read and just 2.9ms access time. Again, CPU utilization shows as a low 1%.

SiSoft Sandra turns in nearly identical figures, with a 24.9MB/s read performance and 11.6MB/s write.

In the latency test, access time is listed at just 2ms.

Now let's compare these benchmark results to a real world OS install.
