The Archives division at the Wisconsin Historical Society has put together a nice resource that answers a lot of these questions about digital file storage and preservation. (I'm in the State Historic Preservation Office and we've been using this as our guide to preserving our digital files.)

Many reasons not to just keep on the thumb drive. My main career for the last 30+ years has been in IT. Thumb drives fail with few options to recover the data. The average cost for professional recovery is around $400-$500.
100,000 KB is 0.1 GB so yes your google account should be able to handle this much data. It is only 100MB.
That said you should use at least a 3-2-1 backup policy on all your digital files. 3 copies, 2 media, 1 offside. For example, have backups on at least two USB devices (hard drives preferred) and one backup in the "cloud" google drive, idrive, carbonite as a few examples.
now for the files. documents should be saved to PDF or PDF/A (archival format)
photos should be converted from JPG, PNG or GIF to TIF format. TIF is a lossless stable format, each time you copy from the other formats a bit of data is lost.
There is a lot more about digital preservation with checking the integrity of the files over time (fixity).
If you have any questions I'll be happy to help, I'm still learning about digital preservation.
Your first steps should be to copy the files from the thumb drive to a folder on a computer and then upload them to your google drive account.

Why not just keep the data on the thumb drive?

Hello folks,
I am in need of some technical help. We have rec'd on a thumb drive, 35 years worth of journals. By each day.
I looked at one year of the pics files. Each year contains ABOUT 100,000 KB.
So, will our FREE google account accept this much data?
Would we be wiser to take it to Kinko's and have each pic printed out?
Your thoughts?
