It's difficult to find reliable hard drives, external or otherwise; having lost everything from two failed WD My Book 1 TB drives (despite being mirrored), plus one LAN drive with a WD 1 TB disk, a couple of Lacies and several Maxtor/Seagates (which, frankly, have been the worst of the lot) there were two ways of looking at where to go next. Either avoid WD at all costs or hang on to the premise that lightning cannot continue to strike in the same place . . . my network. So, needing a replacement back-up for my backed-up back-up, I decided to risk WD once more and went for this Elements USB drive. With no time to consider the ramifications of having to format and mess around, this drive went straight onto one of my Macs and is accepting everything quite happily from my lone remaining SMB LAN back-up. Unlike the My Book, it doesn't sound like someone's operating a chain-saw by my desk -- it's completely silent and, although it's not Firewire or LAN, it'll do as long as it doesn't collapse and die like its earlier counterparts. Truth is, if you've got valuable data, one back-up device isn't enough. Short of storing everything off-site, external drives should now be reliable enough. We'll see how this one copes . . . In terms of usability, this gets five starts; as for durability, only time will tell.
