Designed with SMB customers in mind, the 8TB Red Pro 7200 rpm SATA III 3.5″ Internal NAS HDD from WD is well-suited for medium to large-scale NAS environments with up to sixteen 3.5″ drive bays. Engineered to handle increased workloads, this 8TB 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 sustained rate of up to 235 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, < 10 in 10 14 non-recoverable read errors per bits read, a workload rate of 300TB per years, dual-plane balance control technology, and 1 million hours MTBF for 8-16 bay NAS systems. Shock protection is provided by a multi-axis shock sensor and WD's NASware 3.0 helps increase system compatibility, allowing Red Pro drives to be more easily integrated with your existing network infrastructure.
