Best hard drives for NAS 2025: Synology, QNAP, TerraMaster

The best hard drives for NAS servers are designed to run 24/7 and deliver solid day-to-day performance. Brands like Seagate and Western Digital offer several NAS-focused hard drives that excel at long-term reliability, and the Seagate IronWolf Pro series in particular stands out. I used dozens of hard drives in the decade I've been testing NAS servers, and currently have a 350TB homelab, so I know what to look for in a reliable HDD to use in your NAS. If you're looking to add to your storage requirements or are just getting started with a home server, these are the best NAS hard drives available today.

You can't go wrong with any of these NAS hard drives

Regardless of whatever drive you pick from the list above, you're going to get 24/7 reliability and long-term stability. My go-to recommendation for a NAS drive currently is the Seagate IronWolf Pro series. Seagate delivers that little bit extra in terms of reliability. Having used IronWolf drives totaling over 200TB of storage for several years, I can confidently say that these drives are ideal for most NAS users. With options available from 2TB all the way to 30TB with the new Seagate 30TB IronWolf Pro, you'll find a drive that is ideal for the best home NAS.

Finally, with Synology now selling its own HDDs, the HAT5300 is the default choice for models like the DiskStation DS1522+. The NAS isn't tested with the IronWolf Pro or Red Plus series, so if you're looking to build a high-end server, the HAT5300 is the way to go.

These drives include custom firmware that delivers 23% increased write speeds over similar NAS-focused HDDs, and they're designed for Synology NAS servers. But if you're interested in home use, the Red Plus or standard IronWolf drives should be more than adequate.
