I have a 4GB 'ready-boost' usb stick, which is happy with lubuntu.

So you should be able to use all remaining space after the iso is installed (I guess close to 300 MB on a 1 GB pendrive or flash card). But I think even 300 MB will be full rather soon. If it does not work when you increase the size of the persistent file, I think something might be bad with the device or the file system. Or maybe it is just too slow. An oversized CD iso or DVD iso will leave less space for persistence, and I would not bother trying to squeeze persistence into a 1 GB drive. I bought a cheap ten-pack with 4 GB Sandisk USB 2 pendrives, that I can use for testing various things. But it is much nicer to have USB 3 for persistent live and installed systems because it is much faster when writing huge amounts of small files. (USB 3 pendrives are also faster in USB 2 ports, because the flash hardware is faster.) Also an old HDD, that you connect via USB 2, will be faster than a USB 2 pendrive for the same reason. See this link (Prerequisites: the paragraph about speed). <a href="https://help.ubuntu.com/community/Installation/FromUSBStick" target="_blank">https://help.ubuntu.com/community/Installation/FromUSBStick</a> 4 GB is also enough to install Lubuntu (not a persistent live system, but installed like it were installed to a HDD).
