what SSD do you run?

Currently using a 60GB Kinsgton MS200 mSATA SSD in my X220. It's not a particularly fast SSD.

Having a hard time deciding between upgrading the mSATA SSD or going for a 500GB WD Blue 2.5" SSD. Problem with option two is the lost of storage capacity (I have a 1TB HDD in the X220).

The problem with option one is the prohibitive cost of a new mSATA SSD-- a 128GB Plextor M6M mSATA costs only 5 USD less than the 500GB WD Blue SSD.

The alternative is to get a used Samsung PM851 128GB mSATA SSD, which is less than half the cost of the Plextor. But I've read reports of the PM851 suffering from slowdown issues like the 840 EVO, with no firmware fix available.
