After a reading many posts on this in many different discussion groups, this is what I learned. If you install to a usb flash disk (micro sd card thru apapters etc), the updater for gettting a new version will not work. The updater is hard coded to detect the usb disks and exit. This has been most likely the case for a very long time, perhaps from the very beginning of the chromebooks, and continues to be true with the current cromeosflex.
However, THIS WILL WORK. If you install to an external ssd drive, then the resulting installation will run updater and get the next version when available just like the internal installation behaviour. I haver tested this to be true on one ssd drive. However my ssd drive, brand new inexpensive 264GB (Amazon Choice type), while bootable, was very unreliable and crashed after relatively short periods of running. When running from usb micro sdcards of name brands I rarely have seen a crash after very long time (months, years).
Then I learned the ssd drives have different types of semiconductor, some less expensive drives use single storage cell position to indicate not just 2 values (a bit as in the original designs) but 3 or even 4 values. These are less reliable, though have higher capacities and lower price / GB. When storing data such as images, audios and videos, if there are errors when using, it will go undetected. But an an OS may crash on a single bit error! The majority of use of these disks are for data storage and not for bootable os.
Now I would like to locate a reliable, bootable, external usb SSD drive, where the memory uses only one bit per cell. Almost all the internally used SSD drives in laptops, I would expect to be this type, otherwise they would not be able to run any os.
Any suggestions, or opinions?
