Anyone know what the SSD specs are on the Vaio TX90?

Here's the link to Dynamism's product page: http://www.dynamism.com/tz90/main.shtml
I'm really liking this laptop (who wouldn't) but I kinda want to know which SSD goes in there and what its specs are before I opt for such a pricey option.

Dell is using the Sandisk in their ultralights, retails for 549 by itself. How many other companies are making them?

Quite a few from what I've read. Sandisk, SuperTalent, and Samsung immediately come to mind but I'm sure there are more. I will look up that specific one you mentioned, though. Perhaps it is the one I'm looking for.
