Ranked by measured failure rate (Backblaze AFR). $/TB shows once live prices are wired.

Speed on a NAS is the network, until it isn't

A single modern hard drive does roughly 150-280 MB/s sequential - enough to fill a 1GbE link several times over. So on a plain gigabit NAS, drive RPM barely shows. Move to 2.5GbE or 10GbE, run several users at once, or edit large files off the array, and the faster 7200 RPM drives start to matter, along with quicker parity rebuilds.

Rank by failure rate, then sanity-check price per TB. A 7200 RPM enterprise drive that prices like a NAS drive (Exos often does) is the sweet spot; pay for speed you'll actually use.

Frequently asked questions

Do faster NAS drives actually matter?
For most home use - streaming, backups, file storage - a 5400-class drive already saturates gigabit Ethernet, so 7200 RPM won't feel faster. They pay off on 2.5GbE/10GbE networks, busy multi-user arrays, editing video straight off the NAS, and faster RAID rebuilds. Every enterprise drive (Exos, Ultrastar, MG) is 7200 RPM.
Are 7200 RPM drives louder and hotter?
A bit, yes - higher spindle speed means more vibration, noise and power draw than a 5400-class drive. If quiet and cool matter more than raw throughput, check the quietest-drives guide instead and pair it with good enclosure ventilation.
