This is a single platter Velociraptor drive, the 300GB version has been out for 3 months ish and has 2 platters and is £70 more. This is the same speed as the 300gb version, possibly slightly faster due to not having to read between platters, possibly slightly quieter too and will use less power.
Remember dont vote cold because of price per GB as raptors arent meant for that, they are meant for speed. This is the cheapest i have found this on pre-order. Stock should be around 15th august according to overclockers.co.uk.
There is a new 74gb version too @ £94 ish, it also has a 150GB platter but is short-stroked (half of the platter disabled), but its still the same speed as the 150GB and the 300GB. The old 150gb raptor was discontinued around 2 weeks ago to make way for this new 150GB velociraptor.
