yako ebay eketh nehe 800GB pen drives..ethin uba laga thiyenne kohomda?
You've got to be kidding. There is no way with current RAM chip tech that you can put 800GB into a USB stick that size - heck, they can't get more than 128GB or so into an SSD enclosure right now! This is a total sham. As soon as you write more than 8GB or so, it will start to overwrite itself - guaranteed.
It's not difficult to program the stick to report back that it has "800GB" free. Don't fall for this, people. Just because it's on the Internet doesn't make it true
