Testbed and Methods
The testbed we are going to use for this test session is based on a mainboard with Intel H67 chipset which offers two SATA 6 Gbit/s ports. It is to these ports that we connect our SSDs.
We will compare the ADATA S511 240GB with a few other SSDs of the same storage capacity that have SATA 6 Gbit/s interface. One of them, the Crucial m4, is based on a Marvell controller whereas the rest are based on second-generation SandForce controllers but vary in flash memory type. The OCZ Vertex 3 Max IOPS uses 32nm Toggle NAND flash; the Corsair Force Series GT and Kingston HyperX feature 25nm synchronous flash; and the Corsair Force Series 3 and OCZ Agility 3 are equipped with 25nm synchronous flash.
Here is the full testbed configuration:
- Intel Core i5-2400 (Sandy Bridge, 4 cores, 3.1 GHz, EIST and Turbo Boost turned off);
- Foxconn H67S mainboard (BIOS A41F1P01);
- 2 x 2 GB DDR3-1333 SDRAM DIMM 9-9-9-24-1T;
- Crucial m4 256 GB system disk (CT256M4SSD2);
