I was looking at the DROBO and admiring it's features ... then looking at it's price tag..... It occured to me - there must be a Linux based product out there for free that can do what drobo does? I am mainly concerned with data saftey (raid5) and expandability (offline or hotwswap out smallest drive for larger, even it takes a little time)
Between FreeNas and OpenFiler it LOOKS like OpenFiler can sorta do what i am after - but I thought I should check with the experts!!
Thanks in advance
