The new model, the WD1500 addresses the biggest problem everyone had with drives: capacity. In today’s world, where author of this article can download eight gigs in a single night, a 36GB capacity seems laughable. Especially when you can get 250GB for the very same price as a 36GB model. So, the new Raptor comes with a capacity of 150GB, split in two models. The WD1500AH is a model “for gamers”, while the enterprise version is known under the name WD1500AD and comes with TLER (Time Limited Error Recovery) marchitecture.
Also, the drives support SATA-II and NCQ marchitectures. Anyway, if you want all the latest and greatest in hard drive technology, you can always click on our complementary L’INQ and spend €319 for the server version. The gaming version isn’t available. Yet.

According this write up at The Inquirer, it looks like Western Digital might be making my dreams come true by releasing a new Raptor driver with a 150 GB capacity, SATA-II support and NCQ as well!
