Frequently asked questions

Is 4 TB enough for a NAS?

For a small home NAS, yes. For a growing library, 8 TB or larger leaves more room.

Desktop or NAS drive at 4 TB?

A NAS line suits an always-on box, and a desktop line is fine for a single-drive PC.

Which 4TB hard drive brands are listed?

Seagate and Western Digital (WD) make most of the 4 TB hard drives here, with Toshiba and others also listed. Compare same-recording-method drives, because CMR and SMR differ.

How much do 4 TB hard drives cost per TB?

Across 200 listings, the middle 80% range from about $38 to $73 per TB, with a median of $50. That is in line with the all-HDD median of $50 per TB. Prices change often, so check the current price on Amazon before you buy.
