Do you use a RAID array setup for speed?
 

If you do, which did you go with and did you notice any speed enhancement?

RAID 5, huge difference. :thumbsup

Raid 1+0

really not sure why you recommend raid 5 for speed.

raid 5 is not the best array for speed.

look on the internet for breakdowns of raid arrays regarding speed vs. data security.

if ur interested in speed use raid 0 which offers no failure security but does offer the highest speed of any raid array.

i agree.. just becareful with just RAID 0.. if one drive fails, youre toast..

i really like RAID 1+0.. has some failure security and speed at the expense of usable diskspace.. many people use RAID5 so they only lose one disk of available space (parity).

raid +1

raid 5 on linux -1 *power 8

on intel raid 0,1 or 5 does not much mater

we've actually noticed slower performance going with raid 5 over single disk operations.

well i think you are wrong

thats impossible

:thumbsup :thumbsup
the only way to go...

and why is that impossible

raid 1+0

When you say "speed" are you referring to transfer or seek speed? There's a big difference between a system that deals with large files read mostly sequentially (ie movies) and a system with lots of small or highly fragmented files (ie a database) where the disk head has to move around a lot.

Hmm... Looked into it...

Raid 0 - Fastest. Takes 3 disks and uses them in unison.
Raid 1 - Slowest. Takes 3 disks and mirrors them. No performance enhancement.
Raid 3 - Costs to much and no enhancement.
Raid 5 - Reads fast (but not faster) but requires memory and should use more than one controller to keep up with non raid speeds.
Raid 1+0 (0+1)(10) - Best of both worlds... But obviously more expensive.

Raid 0 - Can work with minimum of two disks, is fastest, no redundancy. You lose 1 drive you are out.
Raid 1 - Cannot work with 3 disks, must be equal numbers. 2/4/6/8/etc. Great redundancy but expensive (one hd per hd). Slow, but not as slow as Raid 10.
Raid 3 - Dunno, havn't had any experience with it.
Raid 5 - 3 absolute minimum, 5 recommended minimum (for performance + less loss of storage). Hardware Raid-5 is great, Software Raid-5 is pretty sluggish but still workable. Very redundant, can lose one HD and array be fine. A 5 HD array will lose about 22% of storage to go for redundancy.
Raid 1+0 - Same as Raid 3 (that is I don't have enough experience with it to talk about it).
