Two New SATA Specs: SATA Express & µSSD
 

The SATA IO working group announced one new spec and that it has begun work on another: µSSD and SATA Express, respectively. These two specs span the gamut from ultra mobile devices all the way to high end PCs and servers. Let's tackle the smaller one first.

Tablets and smartphones are quickly becoming very powerful. We'll see another 20 - 50% gain in CPU performance in the next 12 months, and chances are we'll see a repeat performance another 12 - 18 months after that. As we've learned from the PC industry, increases in processor performance must be met with faster memory and IO. We're already running into IO bottlenecks on tablets. Copying large videos and audio to the current generation of tablets is a pain, with write speeds averaging less than 20MB/s. Faster storage is necessary.
