The S511 utilizes the new generation SandForce SF-2200 series controller, with native support for the SATA 6Gb/s platform. The S511 completely brings into play the revolutionary high-speed performance of solid state drives, embracing a new world of transfer performance. With read and write speeds twice that of SSDs using the older SATA II specification, the S511 reached 550/520MB read and write speeds respectively, with 4K random write speeds as high as 85,000 IOPS in real world testing. This means transferring a 5GB video file can be completed in as few as 15 seconds. In actual testing of Windows 7 boot speed, the S511 clocked an impressive 21 second system boot time, giving full satisfaction to the performance needs of power users.
