Also, parity-based redundancy is far more efficient, in terms of hard drive space, than the full mirroring offered by Greyhole – especially as more drives are added. Greyhole looks like a great idea (similar to ditto blocks in ZFS), but I didn’t want to have to manually split my data into “important” and “unimportant” bins.

I also ruled out unRAID, NexentaStor, and Windows Home Server, because they (can) cost money. (The next section explains why.) This eliminated Linux (I didn’t want ZFS-FUSE because of the performance implications) and OpenFiler. The only easy part was that I wouldn’t settle for anything less than ZFS. Windows Home Server (2007 is often preferred to 2011 because of the Drobo-like Drive Extender).

Software was a lot trickier to nail down, given all the options: Picking hardware was time consuming, but relatively painless. For comparison, the Drobo FS is rated at about 12W (idle) and 56W (busy), with four drives. If I turn BitTorrent off and allow all the drives to power-down to standby mode, power consumption drops to about 29W. Because the NAS will be running 24 hours a day, it should cost about £43 a year to run (1W roughly equates to £1 over a year). I’m fairly happy with this, because the drives are benchmarked at about 4W idle, and 5.6W while seeking. This is while running a BitTorrent client, and so all four hard disks are spinning. The normal total power consumption is about 43W. The hard disks can be noisy when seeking. CPU and hard disk temperatures are normally 35-45☌, depending on the ambient temperature. The motherboard does dynamically adjust the case fan speed based on the CPU temperature. The case includes a PSU fan and a 120mm case fan, which are fairly quiet. I wanted to minimise noise, so passive CPU cooling appealed to me. Newer Atom CPUs, such as the D510, should be more power-efficient overall because of the on-die memory controller and graphics, but none were readily available. Also, FreeBSD supports the Ethernet chipset, which was important (see below). I chose the motherboard because it hit the sweet spot of price, power consumption, number of SATA ports, and availability. (For a 6-bay NAS, the Lian Li PC-Q08 got a decent review, but the Fractal Array R2 did not.) CPU and motherboard

The other 4-bay NAS case option I found, the Chenbro ES34069, was even more expensive.

Some basic instructions would have been nice – it took 5-10 minutes of fiddling to figure out how to get drives inside. The case was a little expensive, but it does the job well. This is almost exactly the cost of a 5-bay Drobo FS, without drives, at £476.54! Case Atom 330 CPU (dual-core) + ASUS AT3IONT-I Mini-ITX motherboard + fanless heatsink ( £112.83).

With that settled, I could pick the hardware: I guessed that 4 x 2TB hard drives with single-drive redundancy would suit me, leaving a usable space of around 5.5TB. SmallNetBuilder is a great resource for finding out more about that sort of thing. This is where the pre-build solutions from Drobo, Synology, ReadyNAS, etc., excel. Nevertheless, maybe you run a small business and prefer to think of a NAS as an appliance – something that has a warranty and a customer support email address. But mainly, I feel it’s my duty to build my own computers. There are also some worrying stories of problems with poor read/write speeds, noise, and the slightly ropey client software. The Drobo FS itself, while a compelling product, is expensive. This post will explain how I picked the hardware and software for my NAS. I realised that a NAS device would neatly solve a couple of long-standing problems I hadn’t got around to fixing: data backup and data organisation. After reading a review of the Drobo FS, I became obsessed with network attached storage (NAS).
