Review on 📀 EASTFUN 4-Pack 16GB USB 2.0 Flash Drive Memory Stick Thumb Drive Jump Drive Pen Drive with LED Indicator, 4 Colors: Rose/Red/Green/Blue by Threlkeld Drauch

I was looking for cheap USB drives that I wouldn't use for various boot utilities, installs and more than 4GB Firmware flashes. Of course, there is always the problem of fake USB drives, where the real storage space is less than the advertised storage space and you just start overwriting data when it exceeds the real storage space. the memory is listed as ECD7947E64C4 - Samsung K9HDGY8U5B - 4CE/Single Channel [MLC-8K]. I ran them through a 3 pass low level factory format with UMPtool and they are indeed all 16GB. The test shows that they are lower, but close enough to the performance of the Sandisk Cruzer Glide (16 GB, USB 2.0). However, the random write performance is pretty poor. You can compensate for this with disk caching in Windows. Below are the test results. Overall it's 5 stars because the price is great, they're not fake and the performance is mostly ok.
