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

I used these flash drives on a regular basis for a period of time without issue. One of them recently failed and I sent it out for data recovery only to find out that the data is all encrypted. The drive has a high level encryption chip built in. I never encrypted anything. The experts told me that this is extremely rare and can’t explain when a cheaper flash drive would even include any sort of encryption but it would cost me thousands of dollars to get my data off the drive. I have lost months worth of work. DO NOT BUY these!!!!

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.

Transferring DVD (audio and video) for family members. Utilized 5 to date. No problems.

Works as expected. 2nd box I’ve bought

Overview: As described. Experience: Have had no issues with storage or transfer times, Very cost effective. I preferer retractable type but flip is fine for most uses. The flip cover is flat and smooth so you can easily label or write on it. Standard lanyard attachment as well. Best bang for the buck I have found without buying in bulk.

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

So far they all work properly. No issues and decent price. Not the fastest drives but get the job done.

We have been using these flash drives for several years, and I rarely have an issues. Occasionally there will be one that just doesnt want to show on the computer, but it doesnt happen often. We order roughly 250+ a year, so I will take 1-3 flash drives that dont work over the course of a few years.

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

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.
