Hello
From the linked article....
According to DTS, the additional memory combined with its I/O management chip drastically improves hard drive transfer speeds: the drive sees speeds above 110MBps in random read tests for data sizes of 64KB to 512MB. Larger data samples than that, of course, will tend to go outside the cache and performance will drop off. And we need remind you that these are manufacturers claims, so take them with a grain of salt.
If trustworthy, 110MBps is an impressive figure considering that many 7200rpm SATA hard drives have sustained transfer rates on the order of 60MBps, and the SATA interface itself tops out at 150MBps

...cost and size will be two of the factors that will influence its success and availability.
