Verbatim SmartDisk External Hard Disk 640GB

Which equates to a stunning 9p for every one of the 640gb on offer. But the compromise is in the features : there are no eSata or FireWire connections, for instance, so it’s USB only. This puts performance behind eSata drives, such as the A-listed Western Digital MyBook but, when compared with the quickest of USB drives, performance was more mixed. The Verbatim was quicker than the Freecom Hard Drive Pro when handling single files, but fell far behind when tasked with groups of small files. This means the Verbatim is only ideal if you’re willing to trade performance for storage.
