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

Package arrived quickly and the drives perform as expected

Just what we needed

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

I bought these USB sticks because the were cheap and had a decent rating. I got less than what I paid for. While they are indeed 32GB capacity, they are absolute garbage. I knew something was wrong when the quick-format to NTFS took over 20 sec. I tried to write 10-15GB video files to these sticks. The write process took 10-15 sec to start then cycled: 16MB/s (3sec) --> 0MB/s (6sec) --> 16MB/s (3sec) --> 0MB/s (6sec) --> . . . . It did this through the whole write. Rather than throw them out, Ive tossed these aside and only use them when I need a give-away USB stick. Thats how Ill get rid of them.

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

Nice option for a low price way to pass pics or documents to another person. And they work.

2 of them Didn’t work :(

I ran RMUSB Prep on all of them, and they all had the stated capacity. Then I reformatted them & will use them as needed. Typically I will use these for install drives for Linux and other downloaded software, instead of using DVDs. Most distributions fit on 4GB, and I have some other 8GB drives for the few that dont. I may also give some away. For my use, I really dont care how fast they are.

*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.
