Benchmark Results: I/O Performance And Access Times
The database test paints a clear picture: the SSD is 12 times faster.
Web servers typically just read data and rarely write. As a result, the Samsung 470 SSD looks even better compared to Seagate's Barracuda XT.
There are no unexpected results in the workstation test, either.
Compared to the hard drive, the access times of the SSD are barely measurable.
