The A-DATA S599 and the Corsair Force SSDs have found two interesting way to us - both rely on the SandForce SF-1200 controller, which provides among other features, such as transparent compression and AES encryption. It also dispenses with the usual external cache - still want the controller to achieve a very high power, has finally developed the SandForce controller originally designed for the enterprise market.
SSDs currently two storage techniques are used: MLC and SLC, in the first technique in a memory cell can be stored four states, hence the name Multi-Level Cell, in the second technique per cell, only two states are stored, would thus
require for the same storage capacity twice as many memory chips as in the MLC technology, which must be paid, of course expensive and therefore for private / home user is not interesting.
On the other side, SLC memory can manage about 10 times more write cycles than MLC memory and also has a higher speed, for enterprise apps, hence, was formerly questioned SLC memory, because there are the claims of the drives is much higher.
SandForce has now made the goal of SSDs with MLC memory Enterprise-ready to make, the outcome is the SandForce SF-1500 controller with the smaller offshoot SF-1200, which is by sacrificing some features better and more suitable for home users. In this article we look at the SF-1200, the Corsair S599 SSD and mentioned in the Corsair in the "Force" series installed.
