Depends what you want it for. Seagate's a decent name, but if it's to have a handy backup drive you can carry around, then I would avoid that one which needs an external power supply. You can get a 1TB USB 3 drive that is powered by the USB itself for 80 to 90 euro. Make sure you get USB 3 because even if you don't have it now, you will in future. I like (and have bought) the Toshiba StorE type but I'm sure there are many equally good. Available online from elara.ie and other sites.
