2. Use kernel software raid to mirror the current Western Digital Caviar 5400rpm 2mb cache 10gb drive with a 10gb partition on a new (but now very cheap) 5400rpm 40gb drive. The remaining 30gb on the new disc would be /home
Which setup would be faster?
A mirror is not faster: write operations have to be done on both hard disks. At best, it will be the same. Read opertions could be faster, perhaps. A raid 5 setup (which is not a mirror) of three disks on three separate cables (IDE) should be faster. Another solution: distribute your partitions. For example, you can have /opt in one disk, and the rest on the other: X environment and applications start faster. Swap partitions can also be distributed. -- Cheers, Carlos Robinson
