Meanwhile Kingmax also belongs to the manufacturers that offer consumer SSDs which are based on a SandForce SF-2281 controller. Despite the fact that this particular drive uses asynchronous NAND flash the manufacturer promises read speeds of up to 550 Megabyte per second. We're really curious to see wether the drive can really achieve this performance level or if the product description should be changed.

Specifications / Delivery

Model	Kingmax SMP35 240 Gigabyte
Capacity	240 Gigabyte
Memory	Asynchronous NAND Flash
Technology	Micron 2FA18NW289
Throughput	up to 550 MB/s reading, up to 520 MB/s writing up to 75'000 IOPS write
Accesstime (read)	< 0.1 ms
Acoustics	no noise
Warranty	3 Years

With the SMP35 from Kingmax you get a 240 Gigabyte SSD which is based on a SandForce SF-2281 controller and asynchronous NAND Flash memory from Intel. These have been manufactured using a 25 nanometer process. This indicates that the memory cells are specified for 3'000 P/E cycles.

A closer look at the delivery shows that there is 2.5 inch to 3.5 inch adapter bracket, a set of screws, a molex to SATA power cable adapter, a SATA III cable and a manual. There is no disk imaging software included in the bundle.
