Raid 0

[JuggernautOfWar 1]

At work we recently built some new computers running four 500GB drives in RAID0. The performance increase is quite substantial (~350%) compared to a single drive. This got me thinking about doing a RAID0 setup at home for increased performance.

I realize there is a x4 chance of HDD failure using RAID0, but if I back up all my data on a 1.5TB external drive I think I'll be fine.

I know ArmA 2 reads/writes to the disk a lot while you are on your travels throughout the game world, loading textures and such. Would I see any improvement in-game using a four drive RAID0 configuration? (~350% increase in read/write time and disk access speeds)

Thank you for your time.:)

My raid array was pretty fast. You'll likely see some improvement, like the improvement people see using SSDs.

I used mirror raid that probably why I can fraps game at 1680x1050 at 25-50fps.

But I never try play without raid.

I have a RAID 0 with 2 disks and to be honest, it doesn't "feel" much faster.

But i plan to get 2 SATA3 SSD's and put them in a RAID 0: ~550MB/s x2!

mirror raid is not striping, so you shouldn't get any performance benefit... at least I don't think so. mirroring makes a redundant copy in case of a disc failure.

I think this is correct.

Well, I changed my raid-0 SSD system from sata2 to sata3 Kingston HyperX SSD (read 555mb/s-write 510mb/s) raid-0 yesterday and I couldnt see big difference compared to old SSD. How ever the difference was huge after going from normal HDD system for SSD raid-0. Definately recommend system for all. Everything loads up just in secods.

I noticed less stuttering when I went from 1 Raptor to 2 in Raid0.

Tho, that was back in 07' and with a pair of 8800GTX/SLI.

Daily backups are a must.

I'm talking about HDDs here, SSDs are too much money still.

yeah, me to. ;)

WD Raptors, 150 gb, @10,000 rpm.

How are the reliability on those things? More than five years ago I had some really bad experiences with WD. I'm going to need some rock solid drives for RAID0.

I've got a SSD RAID array, and yeah, 'tis awesome. Strongly recommend it.

Haven't had any troubles re: reliability as of yet (it's almost 2 years old now), but early days.

Only 1 WD drive I've owned died before the 5 yr warranty expired. I never actually counted them between personal use or used in friends pc's I've built, but I'm sure it's 4-5 dozen. A few have been replaced just for more capacity.

I would give 9 of 10 for reliability.
