The S511 completely brings into play the 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 550/520 MB read and write speeds respectively, with 4K random write speeds as high as 85,000 IOPS in real world testing. This means transferring a 5 GB video file can be completed in as few as 15 seconds. The S511 clocked an impressive 21 seconds system boot time, giving full satisfaction to the performance needs of power users.
