Is the WD Gold 26TB good for a home NAS?

Yes, if your NAS supports 3.5-inch SATA drives and you want maximum capacity per bay. Its 2.5 million hour MTBF suits always-on use, but it is noisier and warmer than slower NAS drives.

How fast is the WD Gold 26TB?

Western Digital rates sustained transfer at about 291 MB/s over SATA 6Gb/s. Real-world sequential speeds are close to that; random small-file performance is typical for a 7200 rpm drive.

Does it work in a standard desktop PC?

Yes. It uses a standard SATA 6Gb/s interface and 3.5-inch form factor, so it fits most desktop cases and docks. Check that your power supply and SATA ports are free.

How does it compare with WD Red Pro?

Both are 7200 rpm NAS-oriented drives. The Gold line is positioned for enterprise workloads with a higher endurance rating, while Red Pro is tuned for NAS use with similar performance.

What is the cache size and RPM?

It has a 512MB cache and spins at 7200 rpm. The cache helps with bursty reads and writes; the spin speed drives the high sequential throughput.

Is it loud enough to matter in a quiet room?

It is louder than 5400 rpm drives, with audible seek clicks and a low hum. In a closed case or a separate room it is usually fine; in a bedroom NAS it may be noticeable.
