5 out of 5 eggs

Pros: Great SSD for older ThinkPads; Latest firmware out of the box. I've deployed about a dozen of these, no issues whatsoever.

Cons: None really. Would like to see the price go down a bit.

Other Thoughts: If your ThinkPad is limited to SATA II (3.0) speeds, these are a great buy. With newer machines (T420/520 and up, X220 and up, W520 and up) one should be looking for a newer drive if speed is their top priority. With that said, these SSDs have been dead reliable in my experience, which is the most important thing in my book.
