Are these the same drive?

Yes. Both are the WD Red Plus 8TB, model WD80EFPX: 5640 RPM, 256MB cache, CMR, SATA 6Gb/s, 3.5-inch. Product B just names the model and lists more specs.

Which is better for a home NAS?

Either one, since the hardware is identical. Both are rated for RAID NAS systems up to 8 bays with a 180 TB/year workload. Buy the cheaper listing, which is Product A.

Is Product B worth the extra $158?

No. You get the same drive. The extra money buys a listing that states the model number and warranty, not better hardware.

How long should this drive last?

WD rates the Red Plus line at 1 million hours MTBF and 600,000 load/unload cycles. Real life depends on workload and cooling; keep it under 180 TB written per year.

Does it use SMR or CMR?

CMR. Both listings confirm conventional magnetic recording, which is what you want for RAID rebuilds.

Will it work in a desktop PC?

Yes, it is a standard 3.5-inch SATA drive. It is tuned for NAS use, so it spins at 5640 RPM rather than desktop speeds.
