The SanDisk Extreme 240GB SATA 3 SSD is a definite recommendation as it’s introductory price is as good to see as it’s performance.  In fact, the entry of the Extreme into the market is very encouraging as it might be a sign of lower prices to come.

storagereview:

Overall we were very impressed by the performance of the SanDisk Extreme SSD. It didn’t offer the fastest performance in every category, but it was able to snag the top spot in plenty of our tests. To come in with that level of performance just as the SandForce market was starting mature is impressive to say the least.

cnet:

The SanDisk Extreme solid-state drive won’t surprise you, but it’s one of the best deals among SATA 3-based SSDs on the market.
