What back up drive for my 2017 iMac?
Indeed to buy a new back up drive for my 2017 iMac with 1Tb HD.
My current back up drive is a 1Tb G Drive that is starting to make grinding noises. I use Time machine and the back up drive has never gone over 0.6Tb and the iMac Hd is less than 0.3Tb.
What size and type of back up drive should I buy, please?
iMac 21.5″ 4K, macOS 10.15
