your export drives(s) should match your media drive
it would be pointless to have a super fast export if the media drive cant match its speed.
if you have raid 0 for media then you should have raid 0 for export etc.
My media drive 4*1 Tb Raid3.
Maybe I can put 2*1Tb Raid0 for export with raid controller(Areca), or 1*ssd (128Gb Samsung 830) with MOB sata3.These are almost a same cost.
But I dont know which is more reliable way? Especially with long time rendering.
Ideally the same as your media drive
Or make 1 large array for both (8 drives)

Scott!You say that, better to use more disk in raid to put export together with media drive?
My Areca controller 1882i, so I can use 8 disks.I use 2 drive in raid0 for media cache.
Still have 6 port. I can create 6 drive array in raid 3? This would be better like separate media drive and export ?
the more disks you have per array the faster it gets.
i would do either 4 drives in raid 5 (forget 3) x 2 sets or just one large 8 drive raid 5 (or 3 if you want to believe its better)
media cache drive is pointless. as is all other crazy drive assignments
you only need media drive and export drive. or 1 big array.
i dont recommmend 1 big array unless its 8 drives or bigger.
these benchmarks are over a yr old but the % difference remains the same.. raid 3 wouldbe the same as well (just longer rebuild times)
Intel SAS RS2BL080 8 Port controller with 512 DDR2 Ram
Single Drive - 101MB
2 Drive Raid 0 - 199MB
4 Drive Raid 0 - 399MB
3 Drive Raid 5 - 204MB
4 Drive Raid 5 - 310MB
8x WD 1TB SATA 6 Gb/s, 64 MB Cache, 7200 RPM
8 Drive Raid 5 - 703.8MB/s read 670MB/s Write
OH one omre thing regardless of redundat raid you need an ext back up.. raid array (5,6) as well)
One big array sure makes it much easier to find your project assets, It is my favorite
Base on your advice I would test with 8 disk big array.Now I have 4 pcs Samsung spinpoint F3 1Tb and 2pcs Seagate Barracuda 1Tb.I have to buy 2pcs more, but as I know better to use same type hdd-s in raid.This is also true when I use a raid controller ?
mixing in not a big problem. however none of the drives you have are enterprise drives
i would never do a raid 3,5,6 without enterprise. far too great a chance of tler error
Now I would buy that 2 more hdd ( Seagate Bararcuda 7200.14 1Tb) .Than I will have
4 * 1TB Samsung Spinpoint F3 + 4*1Tb Seagate Barracuda
.I connect them to Areca 1882I 8port raid controller.
The question is to create 2 set ( 4-4each) RAID5 or 1set ( 8pcs) RAID5.I would have problem to use this 2 different type together in RAID5 ?
In this way I will have this disk setup:
- OCZ revodrive 160Gb - OS, programs
- 4*1Tb RAID5 : media cache, previews, page file, AE global perf, cache, + exports
- 4*1Tb RAID5 : media projects
- OCZ Revo - OS, programs
- 8*1Tb - thre whole thing:-)
Thanks for your help!
You can use different model drives in a raid however this can cause some issues with the controller handling the difference in firmware especially in a parity raid. I would not recommend it but it's up to you.
