With the Extreme SSD 120 GB, SanDisk has a Solid State Drive in its portfolio which is based on the latest SandForce SF-2281 series SSD processor and it also comes with a competitive price tag. The drive features SATA-III support and SanDisk claims that the drive can reach throughput rates of more than 500 Megabyte per second. Also for the IOPS the manufacturer promises sky-high numbers. When writing 4 KByte blocks the drive should be able to hit a whopping 80'000 IOPS and more.

Delivery

The delivery you get with the Extreme SSD from SanDisk is quite poor. There is a small cardboard box which contains the SSD and a manual. There is for example no adaptor to install the drive in a 3.5 inch drive bay. There is neither a disk cloning software. A closer look at the NAND flash memory shows that SanDisk makes use of 24 nanometer Toggle NAND.
