Looking for portable hard drive or hard drive to be infected? And more questions?

I'm currently looking for a "big USB stick" (So with at least 128gb), but I do not want to spend so much. Now, of course, there are already cheap hard drives, but where the cable bothers me. My question: Are there "hard drive sticks"? (Yes, are already opposites, but it's serious xD). So I mean "bigger" USB sticks. (Without cable!).

Next question: Is it possible to install a program (editing program, etc.) on a hard disk / SSD with USB-B / USB-C port to take this program then everywhere? (I do not want to buy the program 5 times, because there are only 1 key per download)

Last question: Is it possible to install Windows on a USB hard drive, and then start other laptops / PCs with this Windows from the hard drive?

M.2 on Usb. Big usb stick

There are 128 GB sticks and portable hard drives / SSDs.

What you are looking for: https://geizhals.de/...40_USB+3.0

Need to be connected to the PC with a short cable, of course, because they are too big to plug in directly. For most models but you need no additional power cable, etc.

It is possible to install there. If the program is not intended for portable use but it can cause problems. Only trying out helps.

Yes, you can also install Windows directly on it and the program. Is then not as fixed as an internal disk, but as long as you can boot in BIOS from USB, this should work.

To "next question"

The program is registered with the respective operating system, so if you have your computer (the operating system) on the stick, it works without problems - only the computer without a stick no longer
