CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0 x64. The graph on the left is for the mSATA SSD and the graph on the right is for the hard drive.
Here we can see the SSD offers significantly better performance than the hard drive. Even though the performance figures aren't amazing for a SSD these days, you'd be hard pushed to tell the difference between this and a top end SATA-600 unit in general real world terms.
