NAS drives are designed to run for long periods of time and handle the read/write needs of a NAS, which are quite different to those in your computer.Īll the major drive makers have disks in their product ranges specifically designed for NAS applications. When choosing hard drives or SSDs for your NAS, look for drives that are made to be used with a NAS, rather than regular drives used in a computer. NAS performance and reliability is heavily dependent on the hard drives you install. It’s not just the NAS you need to consider If you have four or more drives, you can go for a RAID 6 array, where the failure of two physical drives won’t result in any data loss.įor the record, I have a five-bay NAS running as a RAID 5 array. In the case of a three disk RAID 5 array, all of your data is written so that if any one drive in the array fails, your data remains safe. Once you jump to three or more drives, you can look at RAID 5. That way, if one drive fails, your data is safe on the other. With a two drive NAS, you can choose to that the drives as one large volume (RAID 0) or as a redundant pair (RAID 1), where all your data is written to both drives at the same time. If you want to boost performance and add some data protection to the mix, you’ll want a NAS that can support at least two, but preferably more, hard drives. While there are NAS devices out there with a single drive, you can save a few dollars and simply connect a regular USB or eSATA drive to many of the routers on the market today if all you want is a simple, shared storage solution. One of the first questions you need to ask when choosing a NAS is how many drives do you want it to support. So, what makes a good NAS and what’s available on the market? Many of us – me included – have large libraries of digital content we’ve already paid for and want to be able to access at home or work. And even though streaming services like Netflix, Stan, Apple Music and Spotify are changing the way we access media, we still need to ensure data is reliably backed up. We now store more content at home than ever before.
