I wanted to give these to my friends (if needed). So I was looking for something cheap. A lot of laptops don't have a CD/DV anymore, so I went with a low capacity USB 2 flash drive. I finally settled on slightly more expensive 1GB drives for "future" large files. I am using Windows 10 Pro on an ASUS laptop with USB 3.0. (No problem) I randomly checked a few with Defender and Malwarebytes (Premium) and they were all fine. They were preformatted to FAT 32 with 958MB available. I bought red blocks to find them easily. I made a small modification: I put the number with a black marker on the red bar on which the metal tread rotates. That way I know when I see the number it's correct. You don't have to do any of this. They seem cheap as it's hard to find inexpensive SD cards and not everyone has an SD reader. When you plug them in, they glow bright red and blink when data is being transferred. The silver metal guard is rotatable and can be easily removed when not in use. Low storage values are very cheap. Even fits on a keychain. The size in my case 1 GB is written on the bag but NOT on the device. The company I bought from was Fbsctech which sells other related computing gear (always check the storefront for third parties).
