Thread: Best RAID settings for Ubuntu Server? (1+0 or 5 or NAS)

i installing ubuntu server on a:

hp proliant dl380 g4
dual cpu's 3.20 ghz / 800 mhz / 1mb l2
5120 mb ram
6 hard disks on hp smart array 6i controller (36.4 gb ultra320 scsi hd each)


using server capture vhs video, encode, compress, cut, edit, make dvd's, rip dvd's, re-encode more, convert large uncompressed files routine.

have options:

#1) raid set raid 5 (5 discs) 1 spare (6th disk)
liked option, because of spare. disks getting older, going brake down, , need redundancy. however, thought parity processing slow down encoding process. !!!

#2) raid 1+0
thought faster, can either 4 disks mirrored (leaves me 2 disks size of 36.4gb x2)... have 1 spare, , 1 scsi disk not being used sitting in server. (some of waste, unless need quick replacement).

raid 5 have 5 disks @ 36.4gb each , 1 spare
or
raid 1+0 have 2 disks @ 36.4gb each have 2 spares , mirroring.

considering purchasing nas.

given these scenarios (raid 5...raid 1+0....either 5 or 1+0 using nas)

best configuration needs?
thank you.

it depends on how important maximizing hard drive space you. if it's not upmost importance, raid10 not have parity calculations , has potential more fault tolerant raid5 array. if need maximum space, raid5 you.
