You are going to hate this suggestion but Google Drives are good for files you don’t mind people seeing. I don’t keep anything on my computer that I want to keep secret. If I want to keep it secret(bank data, etc), it gets encrypted and put somewhere off the computer.
I partition my hard drives into a program partition and a data partition. I then encrypt the data partition with Diskcryptor. (I back up the data partition to an external hard drive and encrypt that partition as well.) Nobody's gaining access to the data partition without the master password. It's as if the drive doesn't exist. I can easily work with the data on my computer once I've opened it with the master password. Every time the computer reboots, the master password must again be entered in order to access the drive.
