My old 20GB drive keeps moaning that it is full up so i've decided to upgrade. Would i get a good performance increase by using 2 x 40GB drives striped on my onboard RAID (which is currently doing nothing) instead of 1 x 80GB drive?
If you are prepared to spend about £110+ for 2x40 gig drives. Consider this click here . You could partition this to 3x40 gig drives for the same money and have probably one of the best IDE drives on the market.
You must check that your bios will support such a drive.
Just a non-technical, but logical, thought: Why use RAID when you don't need its functions? It will only introduce extra processing whenever you read/write and thus slow the system down.
The best bet must surely be the simplest -- put your new HDD onto a spare IDE lead either as a master on the secondary lead or as a slave on the primary lead. Buy the biggest that suits your budget and PC, and partition it if you really want separate drives.
