On the plus side, removable media provides an inexpensive backup method and makes the availability of an Internet connection moot. USB2.0 and FireWire connections operate at speeds over 400 Mbps, which is substantially faster than a typical Internet or network link.
Third-party backup programs for Windows, including the Microsoft backup application, support any of the removable media options listed below and, with the exception of tape drives, all support Windows-standard drag-and-drop file actions.
CD-R, DVD+/-R and Removable Disk CD-R is the new gold standard for removable storage media. Cheap, compact and easy to use, practically every PC sold is equipped with either a CD or DVD writer. With storage capacity up to 4.2 GB, there's substantial capacity for most data-only backups.
For removable options, Iomega offers external CD/DVD burners and flash media, as well as the classic Zip drive and the new REV drive. The $399.99 USB REV Drive is based on removable hard-platter technology and can store 35 GB native or 90 GB compressed data on a $59.99 cartridge.
External Hard Disk Until the introduction of FireWire, external hard disks were expensive and limited to computers with SCSI host adapters. Today, a number of manufacturers produce external USB and/or FireWire hard drive modules with capacities up to 300 GB at a cost of around $1.25 per gigabyte. There are also inexpensive external housings available that convert any 2.5-, 3.5- or 5.25-inch IDE device into a USB2.0/ FireWire device.
