It's 2012 and more and more of us are generating and hoarding more and more data. Some of you crazies store terabytes upon terabytes of TV shows and movies downloaded off the Internet, on the off chance you'll watch them more than once (hint: you won't). Even if your storage requirements aren't copyright infringement related, the demand for more disk space is off the charts. Despite hard drives topping out at 4TB these days, that just isn't enough to store everything we need. Enter the world of network attached storage (aka, NAS) - little boxes designed to house multiple hard disks and make that aggregate storage avaialble to all the users on your network.
What's generally referred to as a NAS, is a small appliance like computer - something in a cube shape with a network port, space to shove SATA hard disks into and running a variant of Linux, modified for the task of accessing your files across the network. There are also various operating systems, dedicated to turning a spare computer, or a computer built for the specific purpose of storing files, into a NAS -
FreeNAS,
Unraid,
OpenMediaVault and
NexentaStor, just to name a few.
To use a NAS, all you do is configure it appropriately (sometimes easier said than done), and on your Mac, it will appear in the Finder sidebar, under "Shared", like so:
Enter in a username and password (or if you've configured your NAS not to have such things, you don't need this step) and that's it. That little box full of hard drives is now available to all the computers or devices on your network, just as if it was plugged in directly.
If you want, you can even run other services on your NAS, like say, a Bittorrent client, a personal web server, or a remote backup application - remember, a NAS is just a computer running Linux (most of the time), so what it can do is only limited by the amount of CPU power, RAM and what the particular operating system running on it has enabled.
For this review, I've managed to get my hands on a wide range of 4-bay NAS units availble in Australia (listed below with average street pricing via
staticICE). I'll be going through each NAS individually, covering what I did like and what I didn't like about each one, then providing an overall comparison of benchmarks, both synthetic and real-world,
