Do you mean about a separate device that has access to cloud storage or something like that? If you're asking exactly what I was thinking, then this is a very strange way to store data in the cloud. In 2022, there is a HUGE amount of choice for storage in the cloud, ranging from Google drive to iCloud. I've been using
Fastupload lately because it's very convenient and reliable. And as for rare devices for cloud storage, I wouldn't even ask about this. People keep such things exclusively for the collection of old devices (along with dandy and Nintendo).
