Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0 x64.
Even though the Asus F1A55-M LE motherboard doesn't support SATA-600, the included Western Digital 750 GB hard drive doesn't come close to saturating the bandwidth of the SATA-300 port on the motherboard so this isn't much of an issue unless you're planning to upgrade the system with an SSD.
