HDTune Pro - Read Performance
In terms of disk read speed, the Cheetah 15K.6 delivers the fastest single disk performance we have seen to date. The drive delivered a maximum read speed of 166 MB/s (just shy of the stated maximum of 171 MB/s by Seagate) and a sustained transfer rate of 135 MB/s. Both of these numbers are substantially above our 10K SATA hard disk speeds, and are above what many of today's SSD hard drives can offer. The X15.6 also does well in terms of access time with a rated 6.0ms time, half that of conventional desktop hard drives.
