Synology DS218+

Choosing a hard drive for a Network Attached Storage (NAS) device takes a little more consideration than simply picking up a desktop drive with the highest amount of storage. You need to consider a number of factors, including speed, capacity, protection, warranties, and NAS-focused features. Seagate and Western Digital (WD) offer some reliable option, which we've listed here.

Seagate Ironwolf

Seagate Ironwolf HDD

The Seagate IronWolf series is the company's solution for NAS setups, rivaling the Western Digital Red. Similar technology, named AgileArray, is implemented to offer enhanced performance and reliability over desktop drives, and these units can be installed in boxes that support up to eight bays. IronWolf Pro is the next step up with slightly more expensive drives but increased supported bays, workload rates, and a limited warranty.

Most importantly, these drives can be run 24/7 without shutdown. The IronWolf family of NAS hard drives come in 1TB, 2TB, 3TB, 4TB, 6TB, 7TB, 8TB and 10TB versions and three-year warranties. Prices start at $64.99 for the 1TB capacity configuration. Do note that only configurations of 4TB and above sport rotational vibration sensors. The 6TB and above models run at 7,200 RPM.

Western Digital Red

WD Red HDD

WD's Red hard drives are manufactured for NAS use and can be deployed in systems that support up to eight bays. Backed by three-year limited warranties and a powerful brand in the storage market, WD drives are well known to be of top quality, and they last a long time. Red isn't the fastest hard drive series on the market, but using them in a RAID formation can make up for this.

This particular series of drives comes in 1TB, 2TB, 3TB, 4TB, 6TB, 8TB and 10TB versions. Depending on just how much space you require, it's possible to pick one up for around $62 (1TB). Each drive comes with the company's NASware 3.0 for enhanced reliability and performance. It's also worth noting that WD doesn't ship any mounting brackets or screws with these drives.

What makes WD drives appealing is the fact that every capacity option has vibration protection, but if you need faster speeds (drives that run at 7,200 RPM) you will need to fork out more for the Red Pro.
