hey all, I just need a bit of help deciding between a software RAID5 vs software RAID1 array for archival purposes. the RAID will be installed into my hackintosh and shared over the network for TimeMachine backups as well as extra backups from my multitudes of external HDDs. i am thinking 3x1TB WD Greens (RAID5) for $103Aus each, or 2x1TB WD Greens (RAID1). my main concern is data loss and speed of the drives. most setups will clearly equal 2TB of total data storage, we feel that will be enough for a few years (will be backing up 2x laptops + 2x iMacs + the hackintosh). which one will be faster? (i guess this wont matter as the network will be the bottlebeck) which one will be more secure in the end? (our house tends to have power dropouts). the network is a gigabit network over cat5e, we may upgrade to cat6e in the future if the speed benefits are THAT great. i am forced to go with a software RAID via OSX at this point in time because a RAID card is just too costly. my current motherboard in the hackintosh is a GA-EG31M-S2 Gigabyte. it has 4 SATA ports and no RAID support - will OSX still be able to do a software RAID? i am presuming that it can. anyway, what are the main pros and cons for this sort of setup? thanks to all contributors in advance DoFoT9 p.s. sorry if this is in the wrong section.. i didnt know where else to put it!
