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
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.
