The 12TB Red Plus 7200 rpm SATA III 3.5" Internal NAS HDD from WD is built to handle the workloads of RAID-optimized NAS systems with up to 8 drive bays, including home offices and power users, small to medium businesses, and consumer and commercial NAS systems. This 12TB drive operates using a SATA III 6 Gb/s interface, a 256MB cache, and a rotational speed of 7200 rpm, which all help to ensure uninterrupted data transfers with a rate of up to 196 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, < 1 in 10¹⁴ non-recoverable read errors per bits read, a workload rate of 180TB per year, dual-plane balance control technology, and a 1 million hours MTBF. WD's NASware helps increase system compatibility, allowing Red Pro drives to be more easily integrated with your existing network infrastructure, while noise and vibration protection is provided by Rotation Vibration (RV) sensors.

Western Digital's exclusive NASware technology fine tunes drive parameters to match NAS system workloads, which helps increase performance and reliability.

Since your NAS system is always on, a reliable drive is essential. WD Red Plus hard drives are designed for systems that operate 24/7, giving users the confidence of knowing they can reliably access their data.

Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.

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.

Despite using less power, the drives have plenty of bandwidth to handle the mixed performance demands of multi-drive NAS systems.

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. WD's enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability.

Western Digital stands behind their NAS storage solutions with the assurance of a limited 3-year limited warranty and world-class support services for hassle-free data storage.

However, we wouldn’t be able to guarantee a drive like the WD 20TB Red Pro 7200 rpm SATA III 3.5" Internal NAS HDD, B&H # WE201KFGXSPB, would work with the Drobo 8D and give you the full 20TB capacity.

Q: 6. I have old PC based on Asus P5B deluxe. Will 12TB WD120EFBX with this MB. if not, what is the largest EFBX I can use?

A: The Asus P5B Deluxe has SATA ports, so modern drives such as the WD 14TB WD140EFGX Red Plus SATA III 3.5" Internal NAS HDD will be backward compatible with it. However, you will not be able to achieve full speeds with modern drives as there is a substantial spec difference between SATA and SATA III.

Q: 10. If I replace the WD Red NAS 5400 RPM drives in a My Cloud EX2 Ultra with these, how much of a performance difference can I reasonably expect to see?

A: Almost no difference, unless you're using these drives as regular OS drives, where application read/write speed is more critical. If building a NAS I would recommend 5400s, the read speed is fine for streaming, they last longer than 7200s on average, and they're usually cheaper. I got these 7200 at a great price, so it made sense for me at the time.
