Decent idea though given you can have replicates and if you have a 'lose 1 drive past a raid level' type scenario, you really only lose what was lost physically not the entire 'volume'. I like the idea but ZFS has served me quite well and I like the methodology behind it. I also think something designed by a company then built upon/maintained by community will be much more robust than something like flexraid but YMMV. For home use flexraid seems like it is a good fit! -- Bryan Seitz

Chris, My ReadyNas devices (3) all use Flex-RAID. Seems to work great. I've had zero issues since install 3yrs ago.

Re: [H] Nas 3.0
ZFS is something different, it's a file system and logical volume manager. FlexRAID is a piece of software that does data redundancy using parity, similar to conventional RAID but with significant differences. I use it on my media storage server. --- Brian Weeden Secure World Foundation +1 202 683-8534 On Jul 8, 2013, at 13:53, DSinc dsinc...@epbfi.com wrote: Chris, My ReadyNas devices (3) all use Flex-RAID.

Re: [H] Nas 3.0
I used freenas for years. But its now nas4free. The developers who made freenas 5/6/7 great left after ix systems bought them. Freenas9 is good, just nas4free is much more familiar to us freenas7 lovers. ZFS is great, and if I was using enterprise level hardware, that's how id go.
