i dont know much about raid. so is it possible to use 750gb and 1tb in raid ??
also it is possible to use raid 1 or 0 without formatting my current drive ?
please tell me the current price in delhi.

RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and full capacity, but all data on all disks will be lost if any one disk fails.
RAID 1 (mirrored settings/disks) could be described as a real-time backup solution. Two (or more) disks each store exactly the same data, at the same time, and at all times. Data is not lost as long as one disk survives. Total capacity of the array is simply the capacity of one disk. At any given instant, each disk in the array is simply identical to every other disk in the array.

There r other raid configs too. But not many ll be using those for home use.
For RAID 1, u need an identical drive. Which means u ve to get a 750 gb.
For RAID 0, I dont think u need an identical drive, but definitely u need one which ll not bottle neck ur present drive since RAID 0 is used for increasing performance.
Hope this helped u...
