Western Digital is busting Moore's law with its latest hard drive. The VelociRaptor 450GB and 600GB -- the next generation of its 10,000 RPM SATA family of hard drives -- offer new
possibilities for a range of platforms.
The only 10,000 RPM SATA drive on the market, VelociRaptor targets blade servers, high-performance PCs, Macs, professional workstations, and 1U and 2U rack servers. The new model offers twice the capacity and up to a 15 percent performance increase over the previous generation.
Western Digital describes the VelociRaptor as a hard drive built with enterprise-class mechanics that provide durability under high-performance demands with up to 600GB of storage in a 2.5-inch enterprise form factor. With 1.4 million hours MTBF (mean time between failures), these drives have the highest available reliability rating for a high-capacity SATA drive.
Breaking Moore's Law
Charles King, principal analyst at Pund-IT, has noticed an undeniable trend in the storage industry: Bigger and faster rules. For all the talk about Moore's law being the industry's performance metric, he said, the fact is storage capacity and performance in the hard-disk space has continued to outstrip Moore's law in the doubling of performance and capacity.
"As opposed to every 18 months, storage tends to increase performance on the scale of anywhere from 12 to 16 months," King said. "With the new VelociRaptor disk drives, we're just seeing more evidence that even as PC performance continues to march forward inexorably, the storage industry is moving just as fast, if not even faster, to continue to enhance the performance of new PCs and high-performance workstations."
Western Digital also designed the new drives with green factors in mind. The VelociRaptor consumes no more power than the previous generation, according to the company. In addition to being RoHS-compliant, this generation of VelociRaptor is also a halogen-free.
Storage in a Digital World
King said it's critical that storage products continue to evolve on the same pace as PCs, especially considering next-generation content-creation devices like digital cameras. Digital files just keep getting bigger and bigger.
"Storage is an interesting part of the PC paradigm. Storage plays in so many devices now," King said. "Take a look at the devices that people use to define the digital experience -- MP3 players, laptop computers, new devices, and so on. None of those would really be possible without fast, cost-effective, even inexpensive storage."
The 2.5-inch VelociRaptor is enclosed in a backplane-ready 3.5-inch enterprise-class mounting frame with a built-in heat sink to keep the drive cool when installed in a high-performance desktop chassis. The drives are under evaluation with OEMs and will be available through select commercial distributors this quarter. Prices are expected to be $299 for the 450GB and $329 for the 650GB.

Moore's law says nothing about performance. It says that the number of transistors on an integrated circuit will double every 18 months. This does not say the performance will increase by the same amount.
