I been a bad boy and hasn’t posted anything useful for quite a while but I promised someone I’d do it and since hard drives prices recent prices reduction it seems good time to post an update and some explanations.
First on additional SATA controller – To function correctly it’ll probably need firmware upgrade as described in Newegg customer feedback.
Second Regarding : Hard drives – Unfortunately these amazing mammoths of storage aren’t really designed for any serious Raid usage, however their power savings could still used as an advantage in home media server, where performance isn’t main concern.
UnRaid – Is relatively new technology which could be perfect to be utilized in combination with green drives and it writes data without stripping to single drive and one more drive for parity. As advantage you get signle drive failure redundant and power savings (drives not used in write/read aren’t spinned-up. Cons are slower performance and slow array rebuild. Software isn’t free and you’d need to get Pro version which costs now $110 (provide your own flash drive)
If you feel you still want to use regular Raid-5/Raid-Z arrays – FreeNAS (Free), however you’d want to extend the disk park idle time to hour or so by using WDIDLE3 tool. TLER couldn’t be anymore, however there are plenty of positive reviews of Tler-less drives working in software raid arrays.
