You know, my FreeNAS server with no drives.. Xeon e3-1230v2, 32GB of ECC RAM, dual GB Intel LAN, uses less power than your machine at the wall. Mine sat at a solid 35watts with powerd off. Plus, since I have AES-NI I do use encryption for one of my zpools.
I should note that this was not my first choice in hardware.
I had a nice box spec’d out, with ECC and ultra-low TDP processor. Alas, my wife put in her veto when she saw the price tag (about $1.9k), and I had to find ways to get the price tag down to about $1k. Her argument: for that price, I could buy a new hard drive once a year for 20 years in a row and copy everything I’ve currently got over… counter-arguments about how that doesn’t save my data from bit rot were destroyed with a simple “none of your data is that important”.
- small, for home use (Mini-ITX or DTX since I decided on the Node 304 early on)
- primarily to be used with WiFi (802.11n, later perhaps 802.11ac)
- RaidZ2 (6 drives)
- Enough usable space for 2 TimeMachine backups and all of my current data, preferably more (4TB available space would be cutting it very close)
- full disk encryption
- preferably on the fly compression
- preferably low energy consumption
- preferably ECC RAM
At least the A4 has AES-NI (all modern processors seem to have it), so full disk encryption probably sucks by about a factor of 10 less than it would otherwise. Since WiFi is such a bandwidth bottleneck, even this little $46 processor is sufficient (though not ideal).
