On this page we test the performance of the 500 GB 5,400 RPM hard drive.
The combination of an mSATA SSD cache drive and 5400 RPM hard drive helps with the 4K QD32 tests, although sequential read and write results with incompressible data are slightly underwhelming.
The mSATA SSD really shows its effectiveness in ATTO Disk with up to 316 MB/s read performance and 87 MB/s write performance.
My brother has this for work, he works as a manager of a mobile phone retail store. Its very useful for a lot of tasks. But it is quite a bit of effort to carry around. Good screen size though for presentations etc.
