June 16: I've checked and the Amazon deal has ended, with the price rising back to $355. The cheapest 8TB NAS I can find on Amazon right now is the Seagate IronWolf for $300 here. I've also I've found these NAS deals below via Best Buy and Newegg.

Mechanical hard drives (HDDs) still make the most sense when you need huge amounts of dependable storage, especially in a NAS that runs around the clock. If you're looking to expand your setup without overspending, I've found a terrific deal for you.
The 8TB WD Red Plus NAS is currently down to $259 (was $355) at Amazon - a solid $96 off the usual asking price. Considering the 4TB version we tested is a little under $200 right now, that's a very welcome discount.
That's a great price, then, for a drive built specifically for always-on network storage, making it a great opportunity to add capacity to an existing NAS or form the basis of a brand new one.
Today's best WD NAS deal
Reviewing the 4TB WD Red Plus, our drive expert Mark even noted that the 8TB and 10TB models "offer the best value."
8TB of storage is plenty of room for family photos, videos, backups, documents, and media libraries.
Unlike desktop hard drives, this model is built for RAID-optimized NAS systems and uses NASware firmware to improve compatibility with supported enclosures.
It's intended for small and medium business environments, although it's just as useful for home users.
The drive spins at 5640RPM and combines SATA 6Gb/s connectivity with a generous 256MB cache to deliver dependable performance for file transfers, backups, and media streaming.
It also uses CMR recording technology, which many NAS owners prefer because it delivers more consistent write performance than SMR drives during heavier workloads.
Western Digital rates the drive for workloads of up to 180TB per year, making it suitable for systems that see regular activity not just occasional backups.
Support for NAS systems with up to eight drive bays also gives you flexibility if your storage needs is likely to grow over time.
Although SSDs dominate for operating systems and applications, traditional hard drives offer far better capacity for the money and saving almost $96 makes this one of the better prices I've seen recently.
