raid with 2 diffrent drives.

[blaze15301]

i have 2 diffrent drives a 120 and a 180. i know the 180 will go down to a 120 the specs are basically the same but for some reason the 180 has a slower write/read time then the 120. if i raid 0 these and use them as my default drive for the os and some programs will. it be slower then a single platter 500 gb i think that reads writes at about 90/60 or something like that. also i herd the ga-890fx has 4x the speed with raid 0 so idk if that helps or not i cant find any proof of concept on it.

There's no way anyone can answer that without knowing the read/write speeds of the drives to be arrayed. The array should be 1.5-2x faster than the slowest drive.

Like mDust said, can't know without knowing the drives, but I'm guessing it would likely be slower than a new, single platter 500GB drive.

That could only possibly happen if you had 4 drives in the array. The figure mDust mentioned scales..ish a RAID-0 array will be around 0.75n to 1.0n if all drives are identical with drive speed n.

i said to hell with it. im just going to buy another matching 500gb drive here it is if any one is interested. i am actually buying 2 of those. i got the other one in a walmart external kit.

Those are good solid drives. I had 5 of them at one point comprising a large portion of my old fileserver. ..ran for about 3-4 years, 24/7, under heavy use almost 24/7 for about 1.5 of those years, before they finally needed to be replaced (that was back when Seagate did 5 year warranties).

They still have the 5 year warranty on the enterprise class drives. I think the consumer grade drives only have 3 years, but it may have more to do with the model.

I just picked up a 1TB 7200rpm/32MB 3.5" SATA internal HDD at wally world for $75 :D

well i got the drives. they work perfectly but now i have 3 500 gbs exactly the same drive lol. i was not expecting for them to be identical.

RAID-5 time! :D

RAID-5 time! :D

is raid 5 faster then 0?

is raid 5 faster then 0?

No, but there isn't much of a performance difference between the two. RAID 5 uses the third disk for parity which can be used to rebuild either of the two data disks if one fails. It's basically a hybrid of the way both a RAID 0 (striping) and RAID 1 (mirroring) concepts. If you put 3 500GB HDDs in RAID 5 you will have a 1TB array with complete data integrity unless 2/3 drives die at the same time.

well i already have raid zero set up. the 500 is going to be used for media stuff movies music etc.. so far everything i working great. apps are opening up faster now windows still takes like 20 secs to load.

Just pray your drive never fails. :D

i usally dont store anything important on my window drive anyways just gmaes and unimportant things.
