WD Red Plus WD40EFPX - Hard drive - 4 TB - internal - 3.5" - SATA 6Gb/s - 5400 rpm - buffer: 256 MB

<ul><li>NAS System Tuning: Features NASware technology to fine-tune drive parameters for NAS system workloads, increasing performance and reliability.</li><li>Continuous Operation Design: Engineered for 24x7 operation in NAS systems, providing reliable data access.</li><li>Extensive Compatibility Testing: Tested with a wide range of NAS system vendors to ensure compatibility with most NAS enclosures.</li><li>Reduced Operating Costs: Engineered to use less power and run cooler, which reduces operating costs and helps reduce heat in thermally challenged NAS boxes.</li><li>Increased Reliability: Enhanced dual-plane balance control technology improves balance and increases overall drive performance and reliability, with Rotation Vibration (RV) sensors to counteract disturbances in multi-bay NAS systems.</li></ul>

<body>Key Features and Benefits:<ul><li>Tuned for NAS with NASware Western Digital&apos;s exclusive NASware technology fine tunes drive parameters to match NAS system workloads which helps increase performance and reliability.</li><li>Designed for Continuous Operation Since your NAS system is always on, a reliable drive is essential. WD Red Plus hard drives are designed for systems that operate 24x7, giving users the confidence of knowing they can reliably access their data.</li><li>Tested for Dependable Compatibility Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.</li><li>Optimized for Lower TCO WD Red Plus drives are engineered to use less power (versus previous models) and run cooler, which reduces operating costs and helps reduce heat in thermally challenged NAS boxes.</li><li>Powered for Strong Performance Despite using less power, the drives have plenty of bandwidth to handle the mixed performance demands of multi-drive NAS systems.</li><li>Balanced for Increased Reliability Hard drives that are not properly balanced may cause excessive vibration and noise in multi-drive systems, which could reduce hard drive life span and degrade the performance over time. Our enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability.</li><li>Backed by World-Class Support and Warranty As an industry-leading hard drive manufacturer, Western Digital stands behind their NAS storage solutions with the assurance of a 3-year limited warranty and world-class support services for hassle free data storage.</li><li>Desktop drives vs. WD Red Plus It is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS: ��������� Compatibility: Unlike desktop drives, WD Red Plus hard drives are specifically designed and tested for NAS and include NASware technology which fine tunes drive parameters to match NAS system workloads for optimum performance. ��������� Reliability: Desktop drives aren&apos;t typically designed for the demands of an always-on NAS environment. WD Red Plus hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments. ��������� RAID Ready: WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use. ��������� Noise and Vibration Protection: Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.</li></ul></body>

Price

Absolutely the best purchase     available anywhere.  Walmart Really stepped up their e-commerce since rhe Who Knew campaign.  I am  finding awesome products at best prices anywhere.  I am very happy with this product.  It was so easy to make operational and I trust the brand for reliability.  Thank you for providing me the opportunity to express my appreciation.

Would score higher if I could.

I chose this over the Black version because I didn't need the top speed and wanted something that would spin down when idle and would be very quiet in operation.  This is exceptionally quiet, is working fine, and has a good reputation.  I'm using it as a single internal drive, not NAS.

Very Quiet; Solid Choice

Excellent Hard Drive for my NAS. It was recognized right away in my UGreen DH2300 and work flawlessly

Beautiful Drive at a great price

[This review was collected as part of a promotion.] Costs are going up, but the listed price wasn't too far off nominal.

[This review was collected as part of a promotion.] It was a super great price for an exceptional product.

No Surprises

These WD Red Drives are the best.  They are fast and lasts a long time.

These WD Red Drives are the best

[This review was collected as part of a promotion.] Price was cheapest of anywhere and drives have worked great with no issues so far.

Ordered a 4tb drive. DOA.

Ordered another 4tb to replace the one that was DOA. ONLY TO GET ANOTHER DOA DRIVE. CHECKED IN 2 DIFFERENT BIOS, DIFFERENT CABLE %26. DIFFERENT OS.

0/2 ALL DOA DRIVES, ORDERED AT SEPARATE TIMES. WHAT A WASTE OF TIME.

*******DO NOT BUY******

***DO NOT BUY*** DOA

I installed the hard drive just like I do all hard drives per the instructions. unfortunately no matter what my system will not recognize this hard drive I believe it is faulty.
