It ain't flashy, but so long as you don't ever plan on having more than 1.5TB of junk to store on an external hard drive, Transcend's latest should do the trick. The StoreJet 35T promises average write speeds of 42MB/s, and the one-touch backup feature enables your mind to be at ease with the simplest of gestures.
You'll also get intelligent backup scheduling, StoreJet Elite software that offers 256-bit AES file and folder encryption and... well, little else. Mum's the word on pricing and availability, but for those who find this one too rich for their blood, a 1TB model should be landing soon as well.
