Network-attached storage (NAS) drives are becoming increasingly popular. Some meet the needs of business users; others are ideal for home users.


NAS drives are a top solution for several use cases. For example, if you want to make your media files available to all the devices on your local network, have a centralized storage location for all your backups, or access your files remotely, a NAS drive should on your shopping list.

So, which are the best NAS hard drives that you can buy today? Keep reading to learn more.

What Is a NAS Drive?

NAS drives come in two forms—ones that have a storage disk built-in, and ones where you can add your own drives.

The advantage of buying a NAS drive with empty slots is clear: you can upgrade the size of your storage over time as your needs change. On the downside, buying both a drive and separate disks means a higher up-front cost.

Also, keep your eyes open for the newer quad-level cell and penta-level cell drives hitting the shops in the near-future. They’ll increase storage while driving down the price.

    Synology is great but the cost is pretty high, and going NAS is about so much more than mere storage. While media streaming was addressed, it's the tip of the iceberg. Moreover, if cost is the issue for some, these guys are expensive compared to open source solutions that are out there. Hell, it's not fast or anything, but you can make a NAS out of a Raspberry Pi for close to nothing, and with decent instructions online for how to set it up and use it. And lastly, redundancy is one of the major selling points for the flagship NAS vendors like QNAP and Synology. Buying the right drives is imperative for the type of RAID the user might want. And a host of other stuff they overlooked.

    Personally I recommend people AVOID going NAS if they're not comfortable with intermediate level computing.

    So whatever.

    Who wrote this is a noob with no idea... best NAS not only in performance but in cost too are QNAP's and best NAS HDD's are HGST Desktar or other HGST's NAS HDD's they have.
    If you care about performance and reliability you'll never buy WD or Seagate HDD's

    This article is somewhat misleading. The only actual NAS drives you've listed are #6 and #7. Everything before that is just a NAS "unit" or "device".
