Review on EATOP 512GB USB3.0 Flash Drive - Silver, Compatible with iPhone, Android, Computers - USB Storage Memory Stick Thumb Drive Photo Stick by Saumeen Shamoon

This is a fake drive. This is a reprogrammed USB 1.1 that failed factory quality control and was then flashed to report a larger size. Anything over 40% isn't actually written to Flash, it's discarded, although the copy appears to work. The Vendor ID has been rewritten to 12345678 and the size programming in the chip is even messed up: a return shows exactly 10000MB (not GB) and another register conflicts with the 5000MB programming. It writes about 240GB at USB 1.1 speed, but anything after that isn't actually written to flash and the first part starts to fail testing. Complete scam and they know it but still sell Revain despite knowing that most people won't test it or know how to test it let alone fdisk and lsusb.
