Which is better for a NAS?

The WD Red Plus 8TB. It is built for RAID-optimized NAS systems, carries a 180TB/year workload rating, and has a 256MB cache. The Seagate has no stated NAS workload rating.

The Seagate spins at 7200 rpm versus 5400 rpm for the WD Red Plus, so it should win on sequential transfers and desktop responsiveness. WD rates the Red Plus at up to 260MB/s read and 175MB/s write.

Is the WD Red Plus worth the extra?

At $374.99 at Best Buy as of November 8, 2026, it is near its recent high; it was $194.99 on November 5, 2026. If you need 8TB and NAS endurance, it is the right drive; if you just need fast desktop storage, the Seagate is the cheaper fit.

Only the WD Red Plus publishes a workload rating, 180TB/year, which is the better guide for heavy 24/7 use. The Seagate gives no workload figure, so its endurance under constant load is unknown.

Can I use the WD Red Plus in a desktop?

Yes. It is a 3.5-inch SATA drive, but at 5400 rpm it is slower than the Seagate for desktop work. Its strengths are capacity and NAS endurance.

Which has more capacity?

The WD Red Plus, at 8TB versus 6TB for the Seagate ST6000NM0115.
