I have two kids who use the Xbox1 a fair amount. They have a number of games they play and want to get some new ones this Christmas. The Xbox 1 memory is maxed out I'm told. I'm going to help with an external hard drive. I just read the Seagates have a high failure rate, that was disappointing to find out.
Also what size is reasonable? 5TB? Should I go larger?

Any insight on what Brands and sizes would be appreciated.
