WD40EFAX · Refurbished · 1 year warranty
Quantity (units)
Overview
The WD40EFAX is a 4TB WD Red NAS drive that uses SMR recording. Check before you buy: some NAS systems and RAID setups work better with CMR drives, especially during rebuilds, so confirm that SMR suits your NAS model and volume type.
On the spec sheet: SATA 6Gb/s, 5400 RPM class, 256MB cache and a maximum transfer rate of 180 MB/s. Workload is rated at 180 TB per year, with an MTBF of 1,000,000 hours. It draws 4.8 W during read/write and 3.1 W at idle, and weighs 0.57 kg.
It suits home and small-office NAS units used for file storage, media and PC backups, as well as replacing a WD40EFAX already installed in a volume.
Available New and Refurbished with 1 year or 3 years of warranty, and Used with 90 days. Send the quantity for pricing.
