Wavetune

My dad has a pretty decent laptop (asus) but is running low on storage, and asked me (since I have a decent knowledge about and building computers) what to get. He just wants a terabyte (or maybe even two if it’s not a big price difference) external HDD for just dumping files. USB 3 is the only real requirement, other than that I was wondering what the best one is, speed is not that important but value for money and reliability is most important, it’s to last him years. Any info or opinions would be appreciated. Thanks!
