KOOTION 10 Pack 4GB Flash Drive 4gb USB 2.0 Flash Drives USB Drive Jump Drive Bulk Thumb Drive Swivel Memory Stick Black

Purchased this 10 pack as a pen testing solution. They are working so far, but writing to the product and conversion to bootable image drives was incredibly slow. Total write time for an image file (ISO) of 16GB was 32 minutes. Not great if you are in a hurry! Port used was USB 3.0, and this device is USB 2.0. This item was not up to the speed of the USB 2.0 spec, claiming up to 480MB/s. In my writing speed test, I wrote a 16gb ISO file. This took an incredibly long time, at an average write speed of 9.7MB/s. The speed decreased marginally, but steadily, as the write process continued. I might recommend for multiple smaller file solutions. Perhaps office documents to home, or schoolwork to home. In contrast, my tests say this product is not up to larger file work like ISO images.

good storage device

You will be sorry if you buy from this company. Over half of the USBs will not format correctly and have to be thrown away. Huge waste of time and expense. DO NOT BUY!!!!!

Wonderfull!

Love these had enough to hand out to family with grand babies pictures and my daughters pictures on and still had memory left over for them to add their own pictures on

Summary: good drives for the price; decent transfer speeds. Details: Main desktop computer is a Dell XPS 8920. System drive is a 250GB SSD. Two other HDDs for data, 1.0TB and 6.0TB. External USB connections are: USB-C 3.1 (rear), USB-A 3.1 (rear), USB-A 3.0 (front). THe transfer speed difference between the front (3.0) and back (3.1) was negligible. Test Method: The test program I use is ATTO Disk Benchmark (freeware). I tried a few different ones, and settled on this one because the result picture was relatively easy to compare to other results. When evaluating results, I mainly looked at the transfer speeds for files size 1 MB or larger. Pros: good price point; good fit & finish; bright activity LED; decent transfer speed. Cons: None. Recommendations: If you buy a pack of 10, remember to test them all in case any are dead on arrival (all mine were good).

This served me well as I needed these to hand out to my customers after I uploaded their file

They worked great and I will order more!

Received them ahead of time and have already used 4 of them to store information on from my pc.

We always used C/Ds and DVDs to store and transmit data. Now the files are so large that flash drives are the way to go....
