Best hard drives for Synology DiskStation DS220+ NAS 2022

The IronWolf is Seagate's main family of HDDs designed specifically for the best NAS, rivaling Western Digital's Red series. Rocking similar technology, named AgileArray, these NAS drives offer enhanced performance and reliability over desktop-class drives you'd find inside your PC. Up to eight of these drives can be installed inside a NAS, with capacities ranging from 1TB to 16TB.

Like Seagate's IronWolf, the Western Digital Red series of drives is manufactured for NAS use. Like the competition, up to eight of these hard drives can be installed in a single NAS. WD drives are among the best in the business, rocking similar endurance and reliability features to make them last. They're just a little slower than Seagate's offerings.

HGST is actually part of Western Digital, so this means you should expect to see similar performance, reliability, and customer service. These drives are a little more expensive but do come with some handy features for NAS use, including vibration protection, as well as a million hours' mean time before failure. They're ideal for NAS deployment and will last a long time before any should require replacing.

If you need a little more from Seagate's IronWolf family of drives, the Pro range is for you. These have 7,200 RPM motors to drive the heads, resulting in faster performance, and there's also a 300TB per year workload limit. They're pricy but are heavy-duty storage drives for NAS enclosures and support up to 24-bay NAS.

Western Digital also has a pro version of its Red series. These are also more capable than the standard lineup of Red NAS drives, resulting in better performance and enhanced features for extended reliability. You can also throw up to 24 of them into a single NAS enclosure, should you need the highest capacity possible.

If HDDs aren't quite what you're after, you'll want to choose an SSD specifically designed for NAS use. The IronWolf 125 SSD range is precisely this, starting from 250GB in capacity. They're faster, quieter, and draw less power from the wall, but you will be limited in capacity and need to spend more upfront than mechanical drives.

The Red SSD range from Western Digital is much like the Seagate IronWolf SSD family. The drives offer better performance than Red mechanical drives, as well as not having any moving parts for reduced noise and power draw. They're more pricey but well worth it if you need faster transfer speeds.

Seagate's IronWolf Pro 125 series of NAS SSDs offer speeds of up to 545MB/s, rapid for network storage. These SSDs are specifically designed for continuous multi-user NAS applications. The drives also have some neat features like power-data-loss protection, and capacities range from 240GB up to 4TB with a three-year warranty.

Synology has a range of SSDs available that are specifically designed for NAS use. If you require faster transfer speeds than what's offered by HDDs, you'll need an SSD like this.
