Magnetic storage is soon to enter "end game". With Solid State drives now starting to gain in speed and size, the days for the magnetic HDD are soon to see the end of the tunnel. While it's still a few years away at least, we have to deal with what is available and it's good to see companies like Western Digital not giving up on the whole small form market sector.
The Scorpio hard disk has managed to impress us, not only is it able to out perfom the IDE based Momentus, its size has also grown to a healthy 250GB; this is quite adequate for the notebook market or for those building Mini-ITX systems and wanting the 2.5" HDD advantage. If you're looking for a large capacity 2.5" SATA drive which boasts great performance the Scorpio is a very good option.
Overall we would be hard pressed to find a larger capacity 2.5" drive with the same speed, prove and performance.
