simple question about RAID

post #1 of 7
Thread Starter 
Hi guys, i have two different hard drives:
WD 250Gb and Seagete 160Gb
is it possible to RAID them to get one disk with better performance?
My OS installed on SSD, so i need it only for storage.
Thanks.

Different sizes and speeds are fine, you are simply limited to the size of the smallest drive. In other words if you added a 250gb drive and a 160gb drive you'd end up with the following options:

RAID 0 - 320GB total

RAID 1 - 160GB total - you can't use the "leftover" space on
the new drive for anything else, either.

Hope this helps thumb.gif

but if I put them in RAID 0 doesn't it increase the chance of failure?

kind of as in if one drive fails all data is lost that is why all data should be backed up. i would probablly buy a new drive and/or keep the ones you have separate as two physical drives instead of RAIDing them.

It does not increase the chance of failure but if a drive does fail, you loose the data on it unlike raid 1 which stores the same data on two separate drives although does not produce any performance increases like raid 0.

ok i have just set them for RAID0, i really like the performance,i get X2 boost over a single drive in read/write speeds.
it feels like upgrade wink.gif



read speed 66 MB/s ==> 120 MB/s +

thanks all.
