Buffalo USB 3.0 PCI Express card

Now, theoretically, due to the common controller, the cards should perform identically. Tests were done on each card with Hd Tach to compare the performance of some of the latest USB 3.0 hard disks.

With such similar performance, the first conclusion is that NEC’s D720200F1 is a very good and consistent controller; repeatedly delivering the performance expected from such devices. Although the benchmark results are almost identical, there are some differences that deserve closer scrutiny.
