32GB USB 2.0 Flash Drive Pnstaw Swivel Memory Stick Thumb Drive Pen Drives Jump Drive for Data Storage, File Sharing(10 Pack,Multi-Color) (32GB)

These thumb drives work fine for a couple of weeks but then they start dropping connectivity. The drive is plugged in and the light is on and im using the files on it but then it stops showing up on my computer and then reconnects and disconnects over and over for no apparent reason.

Thanks you for the great product and a little surprising items in the packaging. Thanks :):):):):)

Reasonable price and they have worked well. Arrived in nice packaging. Would buy again.

I have used these to load mp3s and photos (not video) from my Mac and Synology server. Loading a single photo or mp3 takes ages. Not worth purchasing in my opinion. These might be useful as 2GB drives for Word documents and the like, but there is no reason for 64GB as it takes ages to load that much data on them. They constantly disconnect from my Mac, and are just generally too slow to be of any use. Id rather have half as many of the faster blue USB drives (even half the size) than these.

Just what I needed to use for photo sharing,

I use these drives for embroidery files that I download from my computer . They work very well.

Great product! Great pricing! And I almost trashed the box without realizing it had strings at the very bottom compartment LOL!!! Just all in all super great for what I need it for!

These are great flash drives.

I bought these to send a few GB of pictures to relatives for ancestry purposes. When I plugged in the first one to my Mac, the light came on the back of the USB drive and I started the copy process. Before any files made it on, my Mac locked up and then rebooted. After booting up again, with the crazy complicated error window description, I initiated the copy process again and it worked fine. Some of the other open windows/apps at the time completely lost work in progress, though. The EXACT same thing happened on the second one. I was smart enough to close all my other work prior to the copying process. The 3rd one copied about 3X as long to copy, but did not hang and reboot. The 4th copied blazing fast, relatively - kinda what I expected to begin with. The 5th was crazy SLOW, taking about 15 min for 2GB, where the regular ones took about 5 min, and the one that took about 1 min. I have plugged each one back in and the files are all present and will open, so Im hoping they work after mailing to family. I will probably never buy an off brand again, and would definitley not use these for any kind of archiving.

Out of the box (of 10) , these flash drives were formatted exFAT. I reformatted to NTFS and tested writing a group of files totaling 120MB and the time spent is 12+min! Painfully long for 120MB that takes under 40sec with a Sandisk Cruzer Glide 64MB formatted NTSF using the same PC. I retested with other flash drives from the box and reformatted NTSF and the result is the same! I subsequently initiated a return that is promptly handled thru the Amazon website. I was packing the flash drives for return today and suddenly Bulb! Maybe the flash drive controller cannot handle the NTSF file system? Correct! If you keep the exFat format these drives came with then transferring the 120MB group of files above is under 45sec which is practically OK. Also reformatting to FAT32 would yield a similar writing time under 45sec. I have not use these drives long enough to report their reliability, but surface testing with utilitie like Minitool Partition Wizard reported No Error. You may surface test in Windows Command Prompt Administrator with command CHKDSK /X /F /R, that I also did and it returned no error. In summary these drives work well with exFAT and FAT32 format but stay away from NTSF format.
