2 different harddrives in raid?

post #1 of 9
Thread Starter 
Hey, i got an WD caviar black dual processor and a brand new baracuda 1tb both sata 3.0, but the baracuda is 100mb faster in read and write than the caviar black aka 180-190mb's.

Will it work to put theese in raid 0? Or do the harddrives have to be identical?

it will work, but you will be limited by the slower of the drives, I am not an expert but it should work

Usually they need to be identical. But if they happen to work together at all. The whole array will perform to the level of the slowest disk for RAiD-0.

I believe it will take the speed of the slowest drive, and it will only double the capacity of the smalled drive.

It'll be limited by the lowest speed drive, but as long as they are the same capacity you won't lose anything else. I've mixed different manufacturers (same capacity) loads of time without issue

Ok, then ill just save up for another baracuda and put them in raid, but then ill have to figure out what to do with the caviar tongue.gif

And one more thing just so i have it figured:

How do i set up 2 hdd's in raid 0? Cause im goin to have those 2 baracuda's on the two white sata ports on the sabertooth. Is the top sata 3.0 ports and the bottom 2 white ones, are those the same? Or do the two white ones have some extra/different features/functions?

ON my old Sabertooth, the colours indicate the controller. There's 4 SATA 3GB, 2 SATA 6 GB on the Intel controller and 2 SATA 6GB on an add on controller. For the life of me though, I can't remember which ones are which, you'll have to have a look in the manual.

Intels native controller is quicker and preferred but best used for SSDs if you have/plan to have one.

From Asus site:

Intel® Z77 chipset :
2 x SATA 6Gb/s port(s), brown
4 x SATA 3Gb/s port(s), black
Support Raid 0, 1, 5, 10
Supports Intel® Smart Response Technology, Intel® Rapid Start Technology, Intel® Smart Connect Technology *4
ASMedia® ASM1061 controller : *5
2 x SATA 6Gb/s port(s), gray
2 x eSATA 6Gb/s port(s), red

I dunno if you can RAID on the add on controller, consult your manual smile.gif

Use that Caviar to back up your data. If you are running in RAID0 you are at least twice as likely to have a failure and your data is unrecoverable at that point. Raid0 works by splitting data between two disks or more so one file is split between two drives. Therefore if one fails half you data is gone. Not just half of your files but half of EVERY file.
