Adorama offers the Crucial M500 240GB mSATA SSD Drive, model no. CT240M500SSD3, for $119.99 with free shipping. (Amazon has it for the same price.) That's the lowest total price we could find by $4, although we saw it for $11 less three weeks ago. It features read speeds up to 500MB/s and write speeds up to 250MB/s.

Note that you can place an order at Adorama but it won't be processed until April 23.
