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

Excelente precio, rapida la entrega. Es un obsequio para mis estudiantes.

*Every* drive from this purchase failed with unrecoverable sectors on Windows 7, Windows 10, and Mint v21. None of the drives presented errors when they were reformatted (variously to FAT32, exFAT32, and/or NTFS), but all of them failed when trying to read data of various sizes. The drives responded at extremely slow speeds, seemingly slower than USB 1 speeds; I couldnt tell if this was error recovery attempts or just the drive being absurdly slow. (And frankly didnt want to invest any more of my time in investigating...) TL;DR: Dont waste your money on these drives - theyre not worth the cost even if they were given away for free, as they dont reliably store data.

They seem to be good for the most part but I’ve ordered these sets a few times, and often there’s one that has some sort of issue and clients have problems accessing the files and it becomes corrupted. Overall a good value for the $. Be sure to format each one and check it before putting files on them and handing them to clients.

I have eaten 3 times. I have never had any failure. they are cheap in price. I dont use them for continuous use

I have used the kootion USB sticks multiple times in the past. I bought this size to save designs from my embroidery machine.

With these flash drives I add a short lanyard to add a touch of color and value added when I deliver my products to my customers

Wonderfull!

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.

the wife uses them for her job works good will buy more later

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.
