Seagate Seven

If you transfer images – particularly large RAW files – between computers on a frequent basis, this 500GB portable hard drive is likely to appeal. It’s incredibly slim – in fact, at just 7mm thick it has the honour of being the world’s slimmest portable hard drive – and it slips almost unnoticed into your bag. The USB3 connection enables fast file transfer – in our tests it delivered average read and write speeds a fraction over 109MB per second.
