SSD naming is a nightmare, especially with OCZ and Kingston drives. Basically they launched the V-Series, then they made a faster V-Series and called it the V+ and now they've made something in between and called it... the V-Series. The new ones use a Toshiba controller based on JMicron's new design. It's apparently not a bad drive, and really quite a good buy at ~£120 (the yanks get it better as usual though, ~$140!). I'm not sure how it stacks up to the Crucial though.
If you find the answer pop a post up. I've been wondering which one is the better drive, but reviews on the new Kingston drive are sparse at the moment and the only one I've read compares it against the new 256MB Crucial drive
Reviewers need a good slap when it comes to testing SSDs. I know they're only sent certain drives and therefore have a limited selection to compare against, but why even bother referencing top-end drives in a budget review? They don't do it with other kit
