WD RE2 500 GB, 7200 RPM, 16 MB Cache
WD’s RAID Edition hard drives are the world’s most reliable server-class SATA drives in the market. With 1.2 million hours MTBF, 100% duty cycle, 5-year warranty, up to 3.0 Gb/s SATA technology, and best-in-class vibration tolerance, WD RE2 drives offer the best combination of superior reliability, high capacity, and optimum performance for enterprise applications.
Key Features
- Superior reliability — designed and manufactured to server-class standards to provide best-in-class enterprise reliability in high duty cycle environments. With 1.2 million hours MTBF at 100% duty cycle, these drives have the highest available reliability rating on a high-capacity drive.
- High capacity — up to 500 GB of storage packed with server-class features and low cost-per-gigabyte value.
- Fast — with a next-generation SATA interface, up to 3.0 Gb/s data transfer rate, native command queuing (NCQ), and 16 MB cache, these drives deliver optimum performance.
- Low power —Active Power Save™ delivers best-in-class seek mode power consumption through an advanced WD firmware which conserves power in active seek modes without degrading performance.
- RAID-specific, time-limited error recovery (TLER) — a feature pioneered by WD, significantly reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
- Rotary Acceleration Feed Forward (RAFF™) — provides best-in-class vibration tolerance by optimizing operation and performance when the drives are used in vibration-prone, multidrive systems such as rack-mounted servers or network storage.
- SecureConnect™ — provides a 500 percent stronger cable-to-drive connection than first-generation SATA hard drives and cables. Also ensures backward compatibility with legacy SATA cables and backplanes. Note: SecureConnect supports only legacy power and does not allow connection to a SATA power supply.
- FlexPower™ — connector technology that accepts power from either industry-standard or new SATA power supplies.
