As you probably know from a previous post, we’re working on Universal versions of all of Shirt Pocket’s applications, including SuperDuper. (We’re in late-stage testing with SuperDuper, and it should be out reasonably soon.)

One thing we’ve been able to confirm: disk I/O on the Intel Macs is much faster than it is on the Power PC ones—seemingly about twice as fast.

In fact, SuperDuper builds about twice as fast on the MacBook as it does on a dual-2.5Ghz G5 desktop, and that’s primarily I/O related.
