New Leopard users have had mostly positive reviews of the OS's Time Machine backup feature, even though it has forced many to undergo significant storage upgrades to keep up with all that archived data.
So we thought it would be useful to direct your eyes to this recent shootout that Mac World held among the most popular external hard drives for the Mac. The Web site took a look at the Buffalo DriveStation TurboUSB (750GB), the Iomega UltraMax Hard Drive (750GB), the Maxtor OneTouch 4 Plus (750GB), the OWC Mercury Elite-AL Pro (1TB), the SimpleTech SimpleDrive USB 2.0 External Hard Drive (1TB), the Western Digital My Book Studio Edition (1TB), and the WiebeTech RTX100-SJ (1TB).
We won't spoil their fun by saying who won, but it is interesting to note that the best performers were those equipped with eSATA ports even though the Mac itself doesn't offer native support for that standard. Users will have to make due with a PCI, PCIe or PCI-X card, or an ExpressCard for the MacBook Pro.
It's also not necessary for a drive to include its own backup utilities since the Time Machine handles most tasks in good fashion. An exception might be made for one-click features that can quickly store changing virtual machine images.
