We installed a 2TB Samsung HD204UI hard drive into the Silverstone SST-TS07B Enclosure. The TS07B was then connected directly to the EC03B, and then a standard USB 2.0 port for comparison. Both results are recorded.
The Silverstone EC03B Internal USB3.0 PCIe Card was installed into an Asus Rampage III Black Edition motherboard with an Intel Core i7 990x Extreme Edition. We tested the EC03B with a Kingston HyperX MAX 3.0 160GB External SSD and the TS07B as detailed above.
We can see that the USB 3.0 performance from the EC03B is superb, with the solid state drive managing a 190MB/s read and 150 MB/s write result. When connected to a standard USB 2.0 port, this speed drops to 33 MB/s.
With a 2TB mechanical drive installed in the TS07B the speeds are identical to direct SATA performance, averaging 135 MB/s in both read and write tests. Again, when hooked into a standard USB 2.0 port, these drop to 33/32 MB/s.
Above, the synthetic results from CrystalDiskMark and ATTO verify our read world performance tests. This highlights the huge gains to be received when switching from USB 2.0 to USB 3.0.
