The best
and the most reliable hard drives for Synology NAS
Windows Central

The choice of hard drives suitable for network-connected storage (NAS) is incredibly important. Western Digital and Seagate are the two storage giants, and both companies offer an almost identical offer designed specifically with servers in mind. This facilitates the selection of the correct unit (s) for your NAS. However, of the two, we would go with Seagate due to the speed for the price.

Best for NAS: Seagate IronWolf

  Seagate IronWolf

The Seagate IronWolf series is the company's solution for NAS configurations, rivaling Western Digital Red, but with more speeds Fast and higher storage capacities available. A similar technology, called AgileArray, is implemented to offer improved performance and reliability over desktops, and these units can be installed in boxes that support up to eight bays. IronWolf Pro is the next step with slightly more expensive units, but with more compatible bays, workload rates and a limited warranty.

Most importantly, these units can operate 24/7 without shutdown. The IronWolf NAS hard drive family comes in versions of 1TB, 2TB, 3TB, 4TB, 6TB, 8TB, 10TB, 12TB, 14TB and 16TB and with three-year warranties. Prices start at $ 60 for the 1TB capacity configuration but can reach a limit of more than $ 500. Please note that only 4TB and higher configurations have sports rotational vibration sensors. Models 6TB and above operate at 7,200 RPM.

If you want the best that Seagate has to offer in terms of NAS storage, take a look at the IronWolf Pro series. All Pro units rotate at 7,200 RPM and can handle 250 MB / s of sustained data transfer, with bursts of about 6 Gb / s. There is also an extended warranty of 5 years and a workload limit of 300 TB per year. The Seagate IronWolf Pro line of units also supports up to 24 bays.

When you need a more powerful NAS

These units are super fast, incorporating 7,200 RPM engines that can allow up to 250 MB / s of sustained data transfer, with bursts of around 6 Gb / s.

Finalist: Western Digital Network

  WD Network

Like Seagate, WD has been creating storage solutions for PCs for many years, and offers reliable drives for any NAS. As with Seagate units, I recommend at least 4 TB. Red WD hard drives are manufactured for NAS use and can be deployed on systems that support up to eight bays. Backed by 3-year limited warranties and a powerful brand in the storage market, WD discs are known to be of high quality and last a long time. Red is not the fastest series of hard drives on the market, but using them in a RAID formation can compensate for this.

This particular series of units comes in versions of 1TB, 2TB, 3TB, 4TB, 6TB, 8TB and 10TB. . Depending on how much space you require, it is possible to pick one up for just $ 64 (1TB). Each drive comes with the company's NASware 3.0 for greater reliability and performance. It is also worth noting that WD does not include mounting brackets or screws with these units.

What makes WD units attractive is the fact that each capacity option has vibration protection, but if you need faster speeds (units operating at 7,200 RPM), you will need to pay more for the Red Pro series.


  • Great value
  • Reliable
  • All have vibration sensors


  • Up to 8 bays [19659014] All run at 5,400 RPM

Western Digital Red Pro

When normal NAS drives simply don't work

Western Digital's professional unit series are even more capable and can support up to 24 bays, they come with a 5-year warranty and more advantage features.

Bottom line

Whether you go with Seagate or Western Digital, it is always a good idea to choose a hard drive designed for NAS use. All the units mentioned here fit that bill. While you can technically use a traditional desktop class unit, I recommend not doing so. Desktop-class hard drives are not designed to run continuously, and are not backed by extended warranties, nor do they come with advanced protection features found on NAS drives.

Seagate stands out slightly since Western Digital does not offer 7,200 RPM units unless you pay more for the Red Pro series. Everything else is virtually identical between the two storage families. This additional speed found in Seagate's higher capacity drives means faster access, which is essential for storing and loading files on your server, are you looking for hard drives to install on your NAS? Go with the Seagate IronWolf.
