I just downloaded SuperDuper today to backup my 120GB MBP hard drive to my new Maxtor One Touch 4 USB 2.0 external drive. I did some test last night transferring single files to the external drive, and I get about transfer rate of 18.18 MB/sec. Here is how I am backing up with SuperDuper. 1. I followed the "How to backup to an Image" FAQ on the forum. I created a encrypted, sparse image the size of my MBP hard drive, 120GB. 2. I then chose the full backup feature on SuperDuper. Finally finished the backup. Here is the log 603,332 files evaluated. 593,396 files copied. Effective copy speed 5.07MB/s. Elapsed Time: 4:12:27 The resulting image is now 72.8 GB At 15,147 seconds, thats about 4.8MB/s on average. Shouldn't it be at least 2-3 times faster ?
