G Drive Mobile squeeks

My G Drive Mobile (1TB) is starting to loudly squeek. It still seems to be backing up but the last two I’ve bought started to make similar noises and failed. Should I rely on this device any longer? This would be the third G-Drive to fail in the past few months so I am very concerned if this kind of drive works with my computer (MacBook Pro). Can anyone offer advice or refer me to more reliable drives? Thanks!
