I have mission critical data that needs to travel well, so the plan is to have copies on two flash drives in case one fails. Cloud storage is not an option.
Needs to have very high quality memory chips, and be very resistant to the elements, shock, water etc.
I don’t need a ton of storage, 16gb is fine and I don’t care much about the speed. Price is not an issue.
Whats the best out there?
Buy a brandname M.2 SSD in low capacity variant and put it in an external case. A bit bigger then a thumbstick, but not as big as an 2,5hdd. If the casing fails (breaking of the usb port for example) you can switch the drive to another case or put it internal in a pc.
A bit more pricey solution, but usb thumbdrives get mostly the lowest quality flash chips.
so an icy box IB-1817M-C31 case is around 30€, add an 128 or 256 gb m2 nvme SSD for around 20€.
