Okay, my guess is you want to permanently attach a flash drive inside the case just for storing Office Files? Overall, I would highly suggest against that. I do a lot with Word (300+ page files). I have four main backups (cell phone, USB drive, external HDD, and SD card) that I keep disconnected from my machine unless I'm updating the files. That way, if there is a surge, the backups will not be affected. Again, flash drives are great for backup, but not meant to be plugged in all the time.
