X-bit Labs reviews two external hard drives: the Maxtor One Touch III FireWire 400/USB 2.0, and the Seagate Pushbutton Backup External Hard Drive.
Maxtor One Touch III (US$470) features 500 GB storage, 16MB buffer, 7200rpm rotational speed, Firewire 400 & USB 2.0 interface. The Seagate Pushbutton Backup (US$380) features 400GB capacity, 8MB buffer, 7200rpm rotational speed, Firewire 1394a & USB 2.0 interface.
The Maxtor OneTouch III has been superior over the Seagate Pushbutton Backup External Hard Drive in this test session. Of course, we should make allowances for the different storage capacity of the tested devices since Seagate's announced 500GB external drive in this series was not available at the time of our writing this review.
It's going to be interesting to watch the changes in Seagate's external HDD manufacturing policy in the future, but so far the Maxtor OneTouch III seems to be the better buy between the two top models.
The most important factors in purchasing external (or internal) hard disk drives would be capacity, buffer size, and price. If given a choice, with all other factors equal, pick the one with a higher buffer.
