They aren't 10 TB products. The storage device (usually an SD card inside a larger case) has been modified to report 10 TB of space but actually has far less than that. Once the actual space has been filled, the device will write over the initial bytes (or some other undesired behavior).

It's not possible to buy 10TB of storage for the prices listed as a hard drive, not to mention as SSD.
