Want to DIY a NAS?
Ars Techinca has a basic walkthrough of the “why not DIY” when it comes to NAS. I would be curious to see how Window Storage Spaces’ performance stacks up to what an off-the-shelf NAS can provide, but aside from that there’s little fault to find with the thought process and component selection (although the price is reasonably high-end for a consumer NAS). The motherboard certainly checks the boxes with 2x Intel GbE and 6x SATA, although it has quite a few extras I’d probably skip if it were me.
Recently I began outgrowing my home file server. It’s an older Mac Mini with 1TB of storage space, and though it has worked well enough for several years (and through more than one OS X Server review), it’s not a great choice for someone who primarily uses it as a file server. It’s not as expandable as I’d like it to be, its Fusion Drive setup offers no redundancy, and as a general-purpose computer it is rendered unnecessary by the 27-inch 2012 iMac on my desk that’s still happily humming away.
