We have recently been experiencing very low transfer speeds when transferring daily backups of between 80-100GB to each of our 3 separate 500GB Iomega drives. (We rotate drives on a daily basis) We had been achieving 80GB+ transferred in 3 hours and now we're up to 90GB+ in about 8 hours!

We've cleaned up the external drives so there's alway's a minimum of 100GB free at any time. (Although as the slow speeds occur with all 3 drives we're sure it's not an external drive issue as it's not just one of them playing up) I've swapped out the USB 2.0 cable and also the drive where the data is backed up to overnight has been formatted and has 280GB free space. (The C: Drive also has 28GB free)

We're not sure why this has suddenly started going slow, but wlecome any ideas as to what might improve it.

The machine is running XP SP3 with 1.24GB RAM, Pentium 4, 2.66GHz.

In order to transfer such a chunk of data you need to ensure that the BIOS has USB emulator on. As per the data calculation the 90 GB data transfered in an ideal scenario through USB Drive would take approx 3.5 Hrs. You can ZIP the data and transfer, you will get a lot faster speed.

Other options are to use a self powered USB hub for the HardDrives
Disable Sharing on PC
Defrag All the HDD Attached to PC
Update the Drivers for Chipset and USB
