When looking at hard drives for your Synology NAS, you'll ideally want to aim for a drive with a 7,200RPM motor and 64MB of cache for mechanical drives or an SSD of any size if you have the available funds. Really, for storage, all you need to bear in mind is the capacity and price. M.2 SSDs can be bought to add rapid cache drives and make accessing files quicker.

We've used the Seagate IronWolf (opens in new tab) for years without fault and find the drives to be well priced to boot. The same can be said about the Western Digital Red (opens in new tab), which are almost identical to Seagate counterparts. If you want to expand on your NAS storage, you'll want to aim big with the more pricey Seagate IronWolf Pro (opens in new tab) and Western Digital Red Pro (opens in new tab).
