Fusion F2 full review
Storage gets smaller and cheaper all the time. Sonnet’s Fusion F2 RAID array is tiny – slightly wider than a CD case, around 20 per cent deeper, and as thick as the bottom half of a MacBook Pro with the lid open. It also weighs very little. Visually it’s not quite as slick as an Apple product, but doesn’t exactly look shabby either.
Inside the tiny box are two 320GB 2.5in drives, linked to the world via eSATA ports. Because eSATA isn’t yet a Mac standard, our review unit also came with a Tempo ExpressCard 34 – one of the few products we’ve seen which use the new ExpressCard 34 format. This works just like an old PCMCIA laptop card, except that it’s smaller and not quite as wide. Installation went smoothly, and the only quirk is the fact that the system uses three cables altogether – two eSATA leads for the drives, and a separate FireWire 400 power hookup.
The F2 is bus powered, but because eSATA isn’t, the power has to be borrowed from the F400 port. This ties up an F400 port when you may want it for other things, and it also eats into battery life – between 20-35 per cent in our tests. It’s not a neat arrangement – the two eSATA leads are required because effectively the F2 is just two disks in a box, and it only works as advertised because OS X’s Disk Utility manages the RAID features. On the plus side, the drives run quiet and are very cool. There’s no fan, and only the barest hint of heat from the case. The drives are also supposedly shock isolated, making them more robust than usual.
