Well, the rumors are true. Western Digital has officially announced a 150GB Raptor SATA drive with all the latest trimmings. The new, 150 GB WD Raptor maintains its high performance in servers and networked storage, where rotational vibration from multiple spinning hard drives robs performance, with its RAFF™ (Rotary Accelerometer Feed Forward) technology. The next-generation drive also offers best-in-class random I/O performance with native command queuing (NCQ), which increases performance by intelligently ordering multiple simultaneous read and write commands, which is common in demanding, multi-user workloads such as servers. Sixteen MB cache furthers the drive's ability to serve and record data quickly for multiple users. The drive offers an average seek time of 4.6 milliseconds (ms).

Yeah I saw those at OcUK, a nice capacity as well (150GB would probably suit most people) On OcUK they were retailing at £214.97 (Including VAT at 17.5%) http://www.overclockers.co.uk/acatalog/westerndigital_sata.html#ahd_2d069_2dwd (scroll down a bit to find the 150GB version)
