I might be taking a couple of really important videos with my Nikon camera and want to have a backup besides the SD card. What gb flash drive do you recommend to store up to 10-30 minutes of video. How much time would it store? Would appreciate any other info also.

If you're taking full HD video (4K) with your Nikon, figure on using 200MB per minute.

If your backup is critically important, I wouldn't trust it to just any old thumb drive. I'd get an external SSD (500+ GB), format it for your computer, and use that.

The answer to your question largely depends on your video - bit rate, frame rate, codec, etc.

The good news is, high capacity flash drives can be had for under $.60/GB these days, so you can get a huge drive for a hell of a lot less than they used to cost.

Smaller ones (like this 256GB stick from Kingston:

are even cheaper.

I prefer Kingston, FWIW. Don't go cheap on brand. No reason to these days.

If it is high-bitrate 4K video, plan on 1GB per minute of video.
If it is HD (1920x1080) video that is compressed in some form (.mp4 or similar), then 30 minutes worth should fit on a 12-16GB drive.
Always get more storage than you need. Jump drives are cheap these days. Get the fastest read/write speed drive that you can (it will save you time on moving the files around).
A 32GB drive might be a good compromise and leave you some extra room. Just in case.

If they are important as stated and you want to keep them "forever".
Get a 128 or 256 GB flash drive. Many are on sale. Get USB 3.0/3.1
Get an external/portable drive from 1T-5T again are pretty cheap on sale (SSD or mechanical). Get USB 3.0/3.1
Even if your current devices are USB 2.0 you most likely will get 3.0/3.1 in the future so just get 3.0/3.1 drives. The download speed is spec is noticeably faster.
Ensure your desktop (or laptop) has a 2-4TB backup drive in it.
Put the files on all back up drives.

Thanks. That helps a lot.
