The Western Digital WD Red WD40EFAX 4TB 3.5" SATA III HDD is a reliable internal desktop drive designed for use with NAS systems. With a rotation speed of 5400 RPM and a cache size of 256MB, this HDD offers fast data transfer rates and efficient performance. The silver and red color scheme adds a touch of style to your storage setup, while the NASware 3.0 feature ensures compatibility and optimization for NAS systems. Featuring a storage capacity of 4TB, this WD Red drive is an ideal choice for expanding your storage capabilities in a 3.5-inch form factor. Not used much out of box, status shows as healthy. I’ve connected to the SATA to reformat as a clean new unit for use.
