The secret of these high theoretical numbers is, of course, hidden away within the drive itself - More specifically, within the drive's controller. OCZ's Vertex 2 series of drives all boast SandForce's SF-1200 controller at its heart, a controller which has made waves on account of its impressive performance. This is achieved via a number of methods - On the one hand, SandForce's "DuraWrite" technology looks to optimise the read-write cycle thrust upon MLC flash cells with compression algorithms while also employing hardware encryption of data written to the drive (albeit with a blank password on devices such as this one). This compression is, according to SandForce, highly effective at reducing the number of writes to a drive, compressing large application installs by over 50% according to their figures - Although this isn't reducing the amount of data stored on the drive, it does mean that the drive controller has to write data less frequently to the SSD's flash memory,
increasing both performance and the drive's longevity.
