Are these actually different drives?

No. Both are the WD Red Plus 8TB WD80EFPX; the -SPC4ZN0 suffix is a seller or region code. Expect the same platters, firmware family and NAS compatibility.

Which is better for a Synology or QNAP NAS?

Either, since it is the same drive. Pick the cheaper listing and buy all bays from the same batch so the drives age together.

Is the 256MB vs 64MB cache difference real?

The WD80EFPX ships with a 256MB cache, so the 64MB figure on B looks like a listing error. Confirm with the seller before paying a premium for either.

Does B really have hardware encryption?

WD Red Plus drives do not include self-encrypting drive hardware encryption; that is the Red Pro and Gold lines. Treat B's encryption claim as unverified.

Is $299.00 a fair price for 8TB?

That works out to about $37 per TB, which is typical for a NAS-rated 8TB drive. Check B's store price against it before ordering.

Both carry the same 3-year WD limited warranty. A states a 180TB/year workload rating; B states none, so use A's figure as the reference for either drive.

WD Red Plus 8TB NAS Hard Drive vs WD Red Plus 8TB NAS HDD

These are the same WD Red Plus 8TB drive (WD80EFPX) sold under two listings, so the hardware decision is already made. Buy whichever store has the lower delivered price and a return window you trust. The best new price for A is $299.00 at Best WiFi Mall as of November 8, 2026; no price was given for B, so compare B's store price against that $299.00 before ordering.
