Because most of these devices at least have a diskless option, you're really only concerned with overall drive capacity, their interface technology, and how much buying them will add to the overall cost of your NAS. These days this only applies to Western Digital as the vast majority of current NAS devices are hard disk-neutral as far as disk brand is concerned. Many other are purchased empty of drives, or "diskless." This was an important consideration a few years ago because it used to be that the NAS vendors who also manufacture hard drives would make sure their NAS devices could only take their hard drives. Some NAS drives are sold pre-populated with disks, oftentimes already formatted for use in a particular RAID configuration. Remember: Mirroring takes two physical drives. Err on the high side of capacity, though it'll cost more now, but you don't want to have to rebuy two hard drives for your NAS to get a higher effective mirrored capacity. Still, for most home users who aren't rabid video-file hoarders, a two-bay NAS should be sufficient, provided that you buy big enough drives from the outset if you'll be mirroring them, meaning simply making one drive an exact duplicate of the other. Check out our RAID explainer for more information. There are different levels of RAID that perform this function in different ways depending on exactly what users need. That means even if one of the drives fails completely, the RAID system can simply take in a new, completely empty drive and repopulate it with the data the failed drive was carrying.

This tech allows the software that manages the NAS devices to distribute and duplicate the data it stores across multiple hard disks. The beauty of a NAS device is that it can use some version of a technology called Redundant Array of Independent Disks (RAID). (Some single-bay NAS drives will allow you to attach a second NAS device or an external hard drive, to that end.) You don't want the only copy of your data residing on just one drive on the network. That's because of the lack of redundancy out-of-the-box. We don't generally recommend NAS drives with just a single bay, unless they are to be used strictly for backing up data that will also reside on computers on the network. These drives will allow NAS makers to fit more drives into their chassis, which means more long-term storage capacity. But that's not an absolute guideline, especially now that newer NAS devices are showing up with support for 2.5-inch laptop-style drives, both platter-based and solid state. Most consumer-grade and home-office NAS units have one or two bays, while models designed for the office have four or more. That's determined by the number of drive bays it includes and to a lesser extent what kinds of drives it can carry.
Since a NAS device is, at the simplest level, just a container for a hard drive or drives (with some added intelligence), the number one spec for any NAS unit is its maximum potential storage capacity.
So you'll need to understand the terms and features before you go shopping. Like any computer peripheral, the features offered by the various NAS units vary greatly to meet these different demands. You'll also need a more powerful NAS if you want to store big media libraries, like a collection of 100,000 stock photos, for your graphic arts studio, for example.
But if you're serving HD videos over your home network to two tablets, a laptop, and your smart TV, all at the same time, you'll want a NAS with higher specifications for memory, processor, and network capabilities. If you're using the NAS to back up your laptops overnight, that's pretty straightforward. Home users may not need to worry about large numbers of users, these days it's the number of simultaneous devices that make a difference. Additional layers of data security and serving files to a relatively large number of users is typically where businesses need to be careful about NAS storage. All of that is relatively simple for a NAS. Once you decide that you need to store files on a network drive, you then need to figure out what you mean to do with them, in order to determine what kind of NAS you need.įor example, a typical business scenario might be sharing access to Office files, like spreadsheets and Word documents, with your coworkers and perhaps backing up select office devices on a regular basis.
