There are several tools available for writing the ISO image to the USB. I have a SanDisk SSD and when I used installed Linux on it, the experience was very smooth, almost like the SSD on the system.

The Linux USB may not work with systems with secure boot enabled.Ībout the slower experience with Linux on USB, if your system has a thunderbolt port, I advise getting a thunderbolt SSD.

When you want to use the Linux USB on a system, you’ll have to go to the boot settings to boot from the USB (unless the system is set to boot from USB by default).

Using a Linux system from USB will always be slower than actual hard disk and SSD.

A system can only have one active ESP partition at a time and it causes issues. The one major problem with this setup is bootloader installation on UEFI systems. The available tutorials on the internet miss the most crucial part: the bootloader.
