Default Western Digital 150GB Raptors

Haha, good news regarding the Raptor drives. 150 GB Western Digital Raptor hard drive from Western Digital will be available very soon. Some places have them already. Speeds are at 10,000 rpm with average read seek time of 4.5 ms. The new 150 GB HD has 16 MB of cache and support Serial ATA II and native command queuing (NCQ). Very important.

Native Command Queuing (NCQ) orders each bit of data, in a queue, in proper order to maximize efficiency and minimize latencies. Hard drives with NCQ reorder the data by arranging the items by how close they are. Current programs do not necessarily take advantage of NCQ, so its true potential has not yet been reached. You may find that multi-threading software will benefit from NCQ a bit more than other applications. When software grow more complex and require the efficiency that NCQ has the potential to offer, then perhaps people will begin to truly appreciate the technology of Native Command Queuing.

Got this off of my hard drive packaging. It's the same thing I said above:

"It was designed to increase performance of SATA hard disks by allowing the disk firmware to internally optimize the order in which read and write commands are executed. This can result in increased performance for workloads where multiple simultaneous read/write requests are outstanding, which occurs most often in server-type applications."
