EASTFUN 5Pcs 8GB USB Flash Drive USB 2.0 Flash Memory Stick Thumb Stick Pen(Five Mixed Colors: Blue Purple Rose Green Gold)

Like it all

My husband bought these. Just found out that after loading a lot of financial info on one of these, he went back to review info a week it didn’t work. Nothing there, tried another computer - nothing! Stuff was on there as he was putting it on - he was checking whole time.

This flash memory works good and I like also the fact with the color pack helps you to identify them quickly.

I like the different colors so that I can use them for different projects.

Got here fast and a great product.

A little slow but a great value.

I was looking for cheap usb drives that I wouldnt use more than 4GB each on for various boot utilities, installations, and flashing of firmware. Of course theres always the problem of fake usb drives where the actual space is smaller than indicated and you simply start overwriting data if you exceed the real space. These use Chipsbanks CBM2199a which is a pretty new flash controller and the memory reported as ECD7947E64C4 - Samsung K9HDGY8U5B - 4CE/Single Channel [MLC-8K] I ran them through a 3 pass low level factory format using UMPtool and they are all really 16GB (ish). Benchmark show they are below but close enough to the performance of a Sandisk Cruzer Glide (16GB usb 2.0). However the random write performance is pretty bad. You can compensate for this with disk caching in Windows. Below are the benchmark results. Overall they are 5 stars because the price is great , they arent fake, and the performance is mostly ok.

I needed flash drives for large-file photos and these are perfect. I also ordered the short wrist cords to attach to them and they are great!

good and inexpensive usb.

Bonitos y hacen su trabajo.
