Title: raid 0 or raid 1
Post by: Eagler on June 16, 2006, 02:51:02 PM

just wondering which raid would offer better performance for AH?

with raid 1 providing a faster disk read wouldn't it be the better of the two?

AH doesn't write that much to the hard drive does it?

Raid 0 is for performance and Raid 1 is for reliability.  Except for maybe during the initial building of textures though, I don't know if you'd notice much of a difference.  AH already has fairly short load times.

Raid 1 is definately slower overall though.

If I'm not mistaken raid-0 & raid-1 will both read at the same speeds; it's the write speeds that are slower for raid-1.

thought reads were slightly faster on the raid 1 as the cpu read off both hd's getting its info that much faster

looking at setting up a raid 1 now as one of the two year old wd's in my raid 0 has failed to the point I can't back it up now. Not looking forward to installing everything again. A duplicate backup in a raid 1 sounds good about now :)

Raid-0 & raid-1 configurations both read off two HD's, the two that have the information split between them, raid-1 has to write the information to three HD's, it splits the info between two & writes the complete information to the third.

 iirc they both read at virtually the same speed, but raid-1 writes a little slower because of the third HD

Raid 1 is disk mirroring involving two disks, not three. Raid is best implemented using SCSI drives/controllers instead of IDE as the SCSI controller can use more than one channel at a time. IDE can use only one at a time and is therefore slower. Raid 5 involves three (or more) disks.

Well people have been discussing the raid set-ups for years, we won't be any different I suppose.

 Some people argue that raid-0 isn't a raid at all.

 I'm just going by what I have read & been told by others that have done raid set-ups.

For home usage you aren't going to see a difference using RAID, especially on SATA or IDE drives/controllers.
They aren't totally hardware RAID solutions unlike SCSI implementations.

Just as well using them as two disks and backing up data between them.

Not tried the new RAID 5 option available on the latest SATA motherboards so can't comment on that.

Generally -
RAID 0 - Read fast / Write fast
RAID 1 - Read fast / Write slower RAID 0

thx Kev
yes, there were jumpers (short 5/6) to lock in the sata150 setting
