The best products that Kingston makes carry the HyperX branding. This is not only one of Kingstons best SSD's ever, it's one of the best consumer-grade SSD's ever.
I put it up against the Vertex 4 since they are both new and of a similar price. When dealing with the smaller drives (240 GB, 128 GB, etc.)The Kingston kills the Vertex 4 when it comes to write speed. The larger Vertex drives do a much better job with the write speed, but the Kingston are still faster.
The HyperX 3k uses the tried and true Sandforce controller. The only complaint I have is that this controller is being used by everyone these days. That is not a bad thing, but if you want to complain, there you go.
You can get the drive bare (and save a little loot) or you can opt for this kit:
