Our take on the Western Digital 8TB WD Red Plus NAS SATA HDD, 3.5" Internal Hard Drive HDD, 5640 RPM, 256MB Cache, CMR

The WD Red Plus 8TB is a 3.5-inch internal hard drive built for NAS boxes, with a SATA 6 Gb/s interface, 5640 RPM spindle and 256 MB cache. It uses conventional magnetic recording (CMR), not shingled, so it rebuilds RAID arrays predictably and is rated for NAS systems up to 8 bays. NASware firmware handles vibration and error recovery in multi-drive enclosures. The best new price is $299.00 at Best WiFi Mall as of November 5, 2026, with 6 stores listing it new.

Questions and answers

Is CMR important for a NAS drive?
Yes for RAID. CMR drives write sequentially and rebuild arrays at predictable speeds. SMR drives can stall badly during rebuilds, which is why WD labels this one CMR.
Will this work in my Synology or QNAP NAS?
It should in any 3.5-inch SATA bay. WD rates it for NAS systems up to 8 bays, so larger enclosures call for Red Pro instead.
Is 5640 RPM fast enough?
For media streaming, backups and file sharing, yes. It is slower than a 7200 RPM drive for large sequential copies, so don't expect desktop-drive transfer speeds.
What's in the box?
Just the bare 3.5-inch drive. No SATA cable, screws or enclosure are included, so check your NAS tray hardware.
When is it cheapest?
NAS drives tend to dip during storage sales and around major shopping events. The current best is $299.00 at Best WiFi Mall as of November 5, 2026; watch for drops below that.
