Android tablets also have large amounts of storage which is presented similar to a USB stick to a PC. This suggests that storage for photographs and media are so affordable that more and more people can take full advantage.
Extrapolating the cost of USB flash sticks and tablets it suggests that 4TB and larger capacity models will not be far off. As flash memory increases the layers the ability to make USB flash sticks of larger capacity becomes possible. 2TB is plenty of room for even 8K video files. The modern laptop can be equipped with 1 TB or even 2 TB of SSD so the 2 TB USB stick can copy the entire machine’s internal storage easily.
For an entertainment system the 2TB capacity can store perhaps 3000 movies. TV shows tend to be smaller so maybe 4000-5000 will fit which is enough for several seasons of several shows. Compressed DVD video tends to be smaller when using H.264 instead of MPEG-2 encoding.

There is no marking for manufacturer, These are available on 512GB to 2TB capacity and are evidently mass produced.
The read/write speed is about 15 MB/s which seems to be level as data is read or written, The transfer rate seems to be steady with video files.
