DOS ain't dead

Windows 7 /// Some Emulator /// FreeDOS (Emulation)

USB flash drives vary a lot in their speed. You often have very limited speed when you use the BIOS for USB access. I once, long ago and for the sake of experiment, ran FreeDOS with Windows 3 (standard mode, not 386enh mode) that way and it felt like running it from a floppy.

If you use USB 3.0 sticks and your BIOS at least has decent USB 2.0 support, you will suffer less, but even then, only "SSD style" thumb drives will give you reasonable speed for what DOS apps need: Access to many tiny bits of data. You only get full speed for accessing large files (for example CF compact flash cards are optimized to write few, but large digital camera photo or video files) or with multitasking OS which use large caches and parallel I/O queues etc.

Given that your Windows 7 computer has a very small harddisk with only 0.5 GB free space, I assume that your computer also has very old USB ports. You should probably just put a larger harddisk or SSD in your computer instead of expecting too much from USB drives.
