So, I browsed ebay searching for USB flash drives, and a lot of 2TB drives came up and some of them even stated 3.0 USB standart. Most of the listings were from China (not any speciefic region), and most of them even had the USB certification. I thought it was fishy but because of the shear volume of listings I assumed they were legit, so I orderd one (for the price of 7 usd) and actually got it in time, a rare accoruns on Ebay, I hooked it to my pc and got about 15 MB/s trasfer speed.
SanDisk 128GB flash drives cost about 20 usd with transfer speed of 100 MB/s transfer speed, so Sandisk flash drives transfer speed is 5x the cheap ebay one but its capacity is 18x lower, so it doesn't make any sense to buy it in 3x the price.
Excuse my english it's not my first langauge, I would like to here your thoughts about how can a Chinese company can make 2TB flash drives and sell them for 7 usd, and why is a company like SanDisk be so behind.
