bit of a dumb question thinking of setting up a stripped raid array over 2 ssd's I already have one on my system. Do I have to use identical drives in the array? or can i use a different type as the second drive?

AFAIK provided they are of the same size you should be ok.

cool i according to wiki i can use whatever size drive i like however if i used say 120gb and a 100gb drive in raid 0 it would only make 200gb not 200gb

Correctamundo (almost) matey.

It will use the lower capacity drive as the common denominator.

2 SSD's striped = uber goodness, but why? You will have no redundancy and the speed of a single drive beats the pants off every other drive before it.

well im gonna use 2 identical SSD's on a raid 0 i have 2x crucial 128GB SSDs rated to 240mbps read so im guessing 2 of these on raid 0 with a decent controller should see some pretty good results, or am i wrong?

k.jacko · 09-02-10, 03:52 PM

You are RICH, no doubt about that!

So you want two RAID 0 setups? Can i ask why, as you very expensive disk setup, yet still won't have any resiliency/redundancy.
Is it for video editing type stuff, where constant read/writes are required?

shanekerry · 09-02-10, 04:03 PM

lol im not rich just happen to have 2 decent hard drives in my pclol

I want to combine the 2 drives on a raid 0 to see what kind of disk read/write speeds i can get i don't have anymore drives to make a raid 10 with otherwise I would, 2 for striping and 2 for mirroring i guess. But i figure that ssds are a lot less likley to fail than standard sata drives

Depends on your controller matey. The intel controllers seem to fair better than the jmicron ones.
Also, this depends on your mobo as well though.

well i got given a AMCC 9550 4 port pci express sata II Raid controller with a 256mb cache so im gonna try this out supposed to be pretty good, came from a server lol
