A Data s511

Real-world performance is really impressive with the S511.

If you put every second saved decompressing .rars on top of each other, they'd reach to the moon. Or something. The 4K read/write figures are also a good indication of performance you'll notice in everyday use.

However, incompressible data write times are underwhelming.

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 60,000 IOPS in real world testing. This means transferring a 5GB video file can be completed in as few as15 seconds. In actual testing of Windows 7 boot speed, the S511 clocked an impressive 23 second system boot time, giving full satisfaction to the performance needs of power users.
