Its been a while since I've asked anything on here.. after some effort you guys got me rolling with linux for a backup server on an old machine and an old promise ide controller running a simple 2 drive software raid mirror... Everything has been fine with it so far although its not in use much at the moment as the machine to be backed up has since been "upgraded" to be water cooled.. but i've yet to fit the controls to turn the pump on automatically so it can't boot up without me being around and so can't run the auto backup task..
ANyways.. For a long time i've been waiting for bigger harddisks to make a backup of my entire music catalogue a possibility, in lossless formats about 400meg an album.. I've just realised that this only really needs around 400-500gig and so is within reach of not too many hdds right here right now..
Its going to take some time to make these music rips and when i do i think i'll want them to have some kind of backup which has got me thinking raid again... I guess this time I would want raid5 as I need more space than is really feasible off only a few drives..
I'm a little wet behind the ears with all things raid but i was thinking that 3x200gig drives would do for the data.. needing a 4th drive for the raid5 parity disk or however it works..
Beyond that i do continue to buy music so some form of expandability would be nice.. 8 channels would allow me to scale although am i right in thinking that i would have to stick to the same sized drives for any extra drives i consider!?
I then guess i need to have seperate channels for each hdd, which starts taking me towards 3ware type cards with hardware to the task.. does this then move me away from using software raid in linux if i have to get these cards?
I ideally would like SATA to try it but i can't find any 200gig Seagate SATA drives in the UK at the moment, only Ultra ATA ..
Anyways if you experts could tell me if i've got the right idea for requirements that'd be great..
Thanks for your time
Cheers
Jim
