"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,<\/p>\n
increasing both performance and the drive’s longevity."<\/p>\n
