Manufacturer description

Western Digital's WD Red Plus WD100EFGX is a 10TB, 3.5-inch SATA hard drive built for small- and medium-business NAS duty rather than desktop use. It spins at 7200 RPM over a SATA 6 Gb/s interface, pairs a 512 MB cache with CMR recording, and runs NASware firmware tuned for multi-bay compatibility. Western Digital rates it for 24x7 operation in enclosures up to 8 bays, with an annualized workload rate of up to 180 TB/yr, so it suits archiving, file sharing, and the sustained read-write load of a ZFS or RAID array rebuild. CMR is the specification that matters most here: unlike SMR drives, it…
