The 2TB Red Plus 5400rpm SATA III NAS HDD 4-Packfrom 2TB Red Plus 5400rpm SATA III NAS HDD 4-Packis 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 2TB drive operates using a SATA III 6 Gb/s interface, a 64MB cache, and a rotational speed of 5400 rpm, which all help to ensure uninterrupted data transfers with a rate of up to 180 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.

Q: 1. Will these work in a Drobo 8D?

A: According to the specifications from Drobo, the maximum volume size for the Drobo 8D is 128TB. This would mean that, theoretically, each bay could support up to 16TB.
