It’s been a couple of months since we looked at an external HDD and the last one we looked at was the Silicon Power Diamond D03 1TB unit. It was a marked improvement over the Silicon Power Diamond D10 750GB drive that we’d looked at previously. We have a direct competitor to Silicon Power today – the ADATA DashDrive HV610 1TB. This is one of the USB 3.0 “entry-level” drives from ADATA and it promises high-end performance at an entry-level price. This drive can be found online for ~$90 and at that price, it’s not the cheapest 1TB 2.5″ drive on the market, but it is still a decent price.
