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

Works as expected. 2nd box I’ve bought

Something I disliked was that when the usb was plugged in it was difficult for the computer to detect. Though it still will detect it as long as you move it a little, was worth the price though.

Does what it says.

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....

Passed all fraud tests. Real deal. MS no longer does “Recovery Disks”. Now they do “Recovery Drives” and they are computer specific. This cheaply let me make a recovery drive for every computer in the house! Finally.

I am using these to copy family photos and give them to my relatives!

At this price I really didnt expect quality from a 10pack of USB 3.0 drives. I expected a few to be defective and poor performance on the rest. However, every single drive passed a badblocks write test with no errors at all. Running basic benchmark showed what I would consider very usable performance. Benchmark numbers can vary wildly based on on setting but this was a favorable comparison to the more expensive drives I had on hand. Assuming they dont degrade later Im pleasantly surprised.

It was easy to use for storage.

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).

Worked fine
