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

These are the perfect size for sharing files with friends inexpensively. After the first 10 were used I realized I want to continue to have them on hand anytime I want to share a file with friends and ordered 20 this time. What a deal.

I needed a bunch of smaller GB memory sticks and this product fit the bill perfectly. Easy to use, and the computer recognized the device every time I inserted a new one. The swivel cap is a nice feature. No worries about misplacing separate caps. On top of everything else, shipping was literally overnight.

Didnt need large thumb-drives, but needed a bunch at a reasonable price. Needed to be good quality too, because theyre going to be stored away for posterity with tons of data by year. I like them so much Im going to get more.

Especially when you need many, e.g., giving away, it is a best.

2 of them Didn’t work :(

Works good for copying data for use later or elsewhere

Its weird to me that at this point in time, flash drives havent gotten significantly cheaper. Considering that a lot of new computers dont have CD drives anymore, why wouldnt flash tech keep up with that? Regardless, these seem to work well. Its a pretty affordable pack, they seem to be well made, and I havent had a problem with data transfer. This is also one of the few flash drive packs that have quick shipping instead of a month-long wait as they make their way from China, so if you need these within a reasonable time frame this is probably your best bet.

I needed Low capacity drives for compatability with usb 2.0 devices. i tested these and yes these are fast usb 3.1 and have 16gb. Authentic -get what you pay for. i copied 16Gb at 20MB/s -reads at 120MB. fast read speeds to play 4k video from. photo of test results attached. good product for cheap affordable price and performance. although i hate the swing type handle. i knew what i was buying and i got exactly what was advertised.

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.

Despite being sold as USB 3.0 flash drives, these flash drives are USB 2.0. My PCs and Macs see them as USB 2.0, data transfer is at USB 2.0 speed. They aren’t so expensive that I returned them, but if they work like USB 2.0 — they’re USB 2.0. If it looks like a duck, quacks like a duck…
