I carry mine in the small side pocket of my little cheapo camera case. Got the case at Walmart for like 5 bucks and I keep a lot of small tech items in it. Sent from my Galaxy S7 Edge.
This is one of my two styles of "go to" bomb proof flash drives. Corsair Survivor, they last and last... Are virtually crush proof and absolutely submersible if you grease the O-ring with a little Dow Corning Gel. I keep mine on my county Comm aircraft mechanics keychain. Corsair Flash Survivor Stealth 64GB USB 3.0 Flash Drive https://www.amazon.com/dp/B00YHL1LN8/ref=cm_sw_r_cp_api_9T-Pyb9XHMKZN I also use for less important files and transient file storage that I use more often a drive that I bought at the Apple Store. Only sold exclusively there and it looks like an ankh. Made by sandisk, mine are 64gb but I'm sure they have 128 or 256 now. I keep one of each on both my key rings, since my house and vehicle keys are on separate rings on purpose.
I don't carry a usb flash drive Most I have access to my cloud storage and/or phone. Sent from my iPhone using Tapatalk
I have a Kingston Data Traveller on my key ring. It hold copies of my ID, medical info and pictures. It's password protected and three people have that password. I have an ICE contact card in my wallet with their info. I know it sounds pretty Jason Bourne but it's a comfort thing. And I'd hate to lose all those pictures of my family.
I second this. The Data Traveller on key ring is really handy. I keep two extras in my bag. Nothing on any of them, they're just-in-case
