Western Digital WD Red Pro 4TB 64MB SATA 6Gb/s 3.5in NAS Hard Drive
WD4001FFSX · Refurbished · 1 year warranty
Quantity (units)
Overview
An earlier 4TB WD Red Pro, the WD4001FFSX has a 64MB cache and a 171MB/s maximum transfer rate. Many NAS units shipped with it, so it is a common like-for-like replacement.
The drive is 3.5in LFF, runs on SATA 6Gb/s and sits in the 7200 RPM class. Sector format is 512e and MTBF is 1,000,000 hours. Power draw is 8.6W during read/write and 6.5W idle, and it weighs 0.75kg.
When one drive in a NAS array fails, matching the model already in the other bays keeps rebuild behavior predictable. This model is a fit for that, and for expanding an array that already uses it.
Three conditions are offered: New and Refurbished with 1 year or 3 years of warranty, and Used with 90 days.
