WD Red hard drives are designed and manufactured specifically for home and

SOHO NAS systems. WD’s proprietary NASware™ technology enables

seamless system integration and robust error recovery controls in RAID

configurations. WD Red drives are engineered for energy efficiency and

reliability making them the ideal solution for demanding 24x7 NAS


Product Features

NASWare™ — WD’s advanced firmware technology enables seamless integration and

balanced performance. Intelligent error recovery controls prevent drives from dropping

off the RAID due to long recovery cycles.

3D Active Balance Plus – We’ve tightened specifications on our exclusive dual plane

balance technology to further minimize emitted vibration, lower noise, improve the hard

drive performance and reduce the potential for errors during read/write operations.

Remarkable energy efficiency – Engineered for energy efficiency and lower

operating temperatures, WD Red drives reduce the demands on the total system,

resulting in a highly reliable affordable solution for 24x7 environments.

Free WD Red premium support line – Exclusively for WD Red customers, WD offers

premium support routed to NAS experts with 24x7, English language and regional


Best In Class Reliability — specifically designed and manufactured for NAS systems

with an MTBF of 1,000,000 hours backed by a leading 3-year limited warranty.

NoTouch™ Ramp Load Technology — The recording head never touches the disk

media ensuring significantly less wear to the recording head and media as well as

better drive protection in transit.

Native Command Queuing (NCQ) — Server feature for performance in random I/O

transaction environments. It aggregates many small random data transfers and allows

the disk to reorder the commands in a sequential order for faster access.

Preemptive Wear Leveling (PWL) — Proactively monitors and prevents magnetic

wear during high read/write duty cycle applications.

Advanced Format (AF) — Technology adopted by WD and other drive manufacturers

as one of multiple ways to continue growing hard drive capacities. AF is a more

efficient media format that enables increased areal densities.
