Playing a bit of catch-up due to an issue that sprang up during my server migration:
AnandTech has posted reviews for two new versions of SSDs from major players:
Intel SSD 320 – While write performance is improved, it’s price and performance don’t match up with the new SandForce products.
Micron C400 / Crucial M4 – Slightly slower read speeds then the C300 and relatively lax garbage collection means for most users SandForce based products will be a better choice.
