Western Digital today announced it will be shipping its WD RE2 (RAID Edition) 750 GB hard drive this month.
With 3.0 Gb/s data transfer rate, WD RE2 hard drives feature Native Command Queuing (NCQ) and 16 MB cache for high system performance.
Addressing a growing high-capacity enterprise market, WD RE2 drives are reliability-rated at 1.2 million hours MTTF (mean time to failure) in high duty cycle environments. Other features incorporated in the new WD RE2 750 GB hard drives include SecurePark, for improved shock characteristics,
StableTrac, for improved vibration performance and
IntelliSeek to reduce power consumption, noise and vibration.
SecurePark technology parks the recording heads off the disk surface during spin up, spin down and when the drive is not operating. The feature improves non-operational shock tolerance by ensuring that the recording heads never touch the disk surface.
StableTrac's motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. Most current hard drive designs feature motors that are only attached on the bottom of the hard drive, which can cause missed read revolutions. StableTrac allows end-user data to be retrieved fast without missing revolutions.
With IntelliSeek, the actuator's movement is controlled so the head reaches the next target sector just in time to read the next piece of information, rather than rapidly accelerating and waiting for the drive rotation to catch up. This smooth motion reduces power usage by more than 60 percent compared with standard drives, as well as quiets seek operation and lowers vibration.
WD RE2 750 GB (model WD7500AYYS) hard drives will be available on the company's online store (www.westerndigital.com) and through select distributors and resellers. Manufacturer's Suggest Retail Price (MSRP) for the WD RE2 750 GB is $265 USD. |
