RAID question

building a new system....question about RAID.....

should/can i run a 36gb 10000RPM HDD from WD AND a 120gb from Seagate at the same time on RAID 0?

whats the diff. between RAID 0 and the others?

and do i need to get SATA or IDE?
 
technically you could run the two drives in raid 0, but they way striping works, you would only have 72gb of usable space
(capacity of smalles drive) x (number of drives)

raid 0 is pure striping, where bits are alternatly written to 2 or more drives
raid 1 is mirroring, where data is constantly mirrored so you always have a perfect backup
raid 0+1 is a combination, which requires 4 or more drives...basically 2 sets of striped drives mirrored

after that i'm not so sure...
but for your current setup raid 0 wouldn't be a good idea cause you'd be losing a whole lot of space

also, its usually a good idea to use drives of identical speed when striping, otherwise you might have latency issues while the controller waits for data to be written to the slower drive.
hope that helps

S-ata or ide doesn't really matter yet...but if you're buying a raid controller you might want s-ata to be future proof.

you would be better off getting another 36GB drive or another 120GB Drive. because it will strip but it will be only 72GB so thats no good here. you could run JBOD that will let you run the 36 & 120 at the same time as one drive but you wont get any speed boost. in fact you might lose some speed in a JBOD config with those drives.
