I picked up this news this morning and I thought I'd share since it actually provides a datasheet to discuss the drive. Unfortunately, no pricing is available yet but one can expect prices to appear in the next month.

The Register has the article

The drive uses 2-bit multi-level cell technology to produce its 256GB capacity and this is twinned with a Samsung-developed controller using an ARM processor core. The SSD reads data at 220MB/sec and writes it at 200MB/sec and does so across a 3Gbit/s SATA interface.

It comes in a 2.5-inch form factor, with 64GB and 128GB versions in 1.8-inch form factor packaging.

Performances sounds nice, let's see if the prices will be as nice
