"For those not familiar with the Cheetah family, Seagate's premier high-end workstation/server drives have had a long history of top performance dating back to their release of the first 10,000 RPM drive on the market. The Cheetah line of drives, as the name implies, are known for breaking all current speed barriers in the hard drive industry and the Cheetah X15 36LP is no exception. This drive at a rotation speed of 15,000 RPM and an access time of 3.7ms beats the previous Cheetah, the Cheetah X15, in access time by .2ms. The 2nd generation also features double the cache going from 4MB to an previously unheard of 8MB. This drive, like the previous Cheetah, uses the fastest available Ultra160 SCSI interface but will also be available in an Ultra320 model when the SCSI controllers supporting that speed begin to ship.

Beyond the specs, Seagate sports several other technologies to make you a bit more comfortable with your drive purchase. The first is Seagate's "3D Defense System," (the three D's are Drive Defense, Data Defense and Diagnostic Defense) and provides a set of in-drive diagnostics that make sure your drive is functioning properly at all times. This system does many things including data integrity checks and routine drive diagnostics. The next technology, dubbed "SeaShell," is Seagate's special packaging which makes the drive much more durable in both its non-operational and operational states. This packaging is a big deal to anyone who has ever dropped a drive one too many times while performing maintenance or accidentally bumped a system a bit too hard while it was on only to hear the painful clicks of a dying drive. This additional protection is particularly important with a drive running at such a high RPM. The final mention of technology is Seagate's Sound Barrier Technology (SBT). This is similar to the SeaShell technology as it is partially a packaging technique to minimize drive noise.

There's no doubt that Seagate puts a lot of work into the pursuit of bigger, faster hard drives. But with this Seagate also realizes that speed is not always enough and that reliability is also a top concern. Technology is what has put them on top in the past. Where does this place them with this drive?"
