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)

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.

Pretty but so slow. I wont buy again.

Works right away on modern Macs, no formatting required. Blinking light for drive reads especially entertaining.

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

Worth buying it. No issues so far. Received in time. Satisfied.

Pros: feel and look high quality. No plastic housing around contact points that cracks and is flimsy causing poor connection later (which I have seen). Kudos to Pnstaw on quality packaging too, your customers worldwide thank you for not just dropping them in a plastic bag. main pro: good luck find a better value or quality for the price tag. CONS: 1 of the 10 was DOA. Other 9 worked fine but . . .are . . . SLOOOWW. From local HDD was around 4mb/s on one, from NAS across Cat-5 to another was brutally slow < 2 Mb/s but was also moving large chunk at once (should have used copy instead, and del original after finished, I think windows may handle that faster?) was 12.8gb pasted at once. *for frame of reference tech/specs: NAS unit is RAID setup on standard magnetic HDDs [2x500gb] 7200s and yes, that data copying was the only thing reading/writing actively (PC was not online updating anything or other apps running). ADVICE IF YOU PURCHASE: when formatting FAT32 is old but works better on all types of devices (not just PC). DRAWBACK is FAT32 max file size is around 4gb and more likely/easily files can be corrupted. So if you are transferring large audio/video/zip files you will definitely want to format as NTFS when you first get it. I would say everyone should try NTFS first really... f you will only use in windows youre good, and if not - COPY some files to it to test/try on your non-windows device in question. If it doesnt work format again (FAT)

Correction: After testing the USB is 32GB formatted using FAT32, which gives an Insufficient Disk Space error message if the file to copy is over 4GB. After reformatting the USB drive to NTFS I was able to copy a 5GB file onto the drive.

Good product. Great packaging. Unable to rate durability until reasonable time of use.

So far I like them Will be nice to have when needed

Perfectly fills the need of an old system that cant see larger memory. The 10 pack comes in a quality package as well, that can be used for storage
