The capital T basically measures the bandwidth of your memory.
And if you are using software RAID, then it is less than informative. It works OK for RAID1 and 4 but not so well for 0 or 5, especially not for 0, where it is possible to exceed the speed of a single disk. But my measurements on creation and updating show XFS on a par or slightly better than ext2 which is itself 50% faster than ext3. (Yes, ext3 is like 66% the speed of ext2). Civileme
