Special Notes / Requirements Note 625 MB/s is the theoretical maximum bandwith available.  Data throughput will be less due to overhead.  Actual performance will also vary due to factors such as host processor, SSD/HDD used, drive buffer, and other devices sharing the same bus, etc.  Real world performance is typically 450 MB/s sequential read and 450 MB/s sequential write using an SSD; 85 MB/s sequential read 85 MB/s sequential write for a 5400RPM HDD.
