You can use Google Translate for the link and pages to better understand their issues within.
Sometimes an usb flash drive gets wonky and will not allow data writes to it, and SSD’s are sometimes known to fail this way soon after installation , so if a re-install does not work because of that, it’s probably best to, so as to save time (and money), to go and get the best SSD drive you can find to replace it.
OR: A hybrid drive uses the standard form factor but uses a large solid state memory platform to speed things up, and also includes the old traditional disc platter system; these tend to be more reliable, but are faster than the platter-only systems, and are more durable and reliable over time than some SSD’s appear to be.
