Performance - USB 3.0 Storage SSD SATA3 (6G)

Performance - USB 3.0 Storage SSD SATA3 (6G)

With the modern SATA and USB 3.0 controllers we started adding SSD performance numbers measured on such interfaces (when applicable). Putting these in nicely styled charts would be better, but with technology so new we just do not have anything out there yet to compare to, so here are some raw peak performance numbers. We use an A-DATA N002 Solid State Drive which has both a SATA2 and USB 3.0 port.


Above, you can see an N002 series A-DATA Solid State Drive running over the USB 3.0 controller on this motherboard. The implementation works well. Obviously the N002 write performance is limited at roughly 200 MB/sec so we completely max out what the device can manage.

USB 3.0 on the Z77 seems really fast. SSD performance on the AHCI Intel SATA3 controller then, the performance you see below is a SATA3 SSD performance indication.

ASUS Z77 SabterTooth

Above, a SandForce 2281 based SSD connected to the SATA3 (6G) Intel controller. AHCI mode is enabled in the BIOS, especially with SSDs that helps a little on peak performance. The Intel SATA3 controller is the fastest of any motherboard really.
