Our standard video card platform, which we use for hard drives and SSD test, has one issue when it comes to the A-DATA N002 drive, it does not support USB 3.0. While you can plug in the USB cable into a USB 2.0 port, doing so will give less performance than using a true USB 3.0 port. In this case I began a search for a USB 3.0 motherboard to fit the bill.

The ASUS P6X58D Premium is the latest motherboard from ASUS. This board supports not only USB 3.0 but SATA 6 Gb/second ports. The X58 chipset sports enough PCI Express lanes to siphon some off for USB 3.0 and SATA 6 Gb/second without sacrificing video card performance as a P55 or H55 chipset motherboard would do without a bridge chip. The P6X58D Premium is a great choice to test this SSD.

One issue in installing Windows and running tests on a hard drive or SSD drive is that some system resources will be used up running the tests on the same drive as the OS is installed on. I paired two WD Raptor SATA HDDs in RAID 0 mode, installed Windows 7 and ran the tests off the A-DATA drive without an OS on it. HD Tach requires an un-partitioned drive to run the write test so it would not have worked anyway.

Performance on the A-DATA N002 drive is really impressive. A-DATA claims a sequential read/write speed of 200MB/second for read and 173MB/second on the write for the USB 3.0 interface. In my testing I reached speeds of up to 196.4MB/second on the read and 170.1MB/second on the write right within the range given by A-DATA with differences of 1.5% being negligible. Using the SATA interface I was able to get even higher performance scores across the board, scoring well above average performance when using the SATA interface. A-DATA designed this drive themselves and the performance shown by this drive is excellent.
