Review on 💽 10 Pack USB Flash Drives - Exmapor 2GB Swivel Metal Thumb Drive with LED Indicator & Lanyards - Mix Colors by Isaac Simpson

Pros: Drives are very cheap and good enough to store small files like text documents. The build quality seems solid. Cons: Possibly the slowest drives I've had in 15 years. The speeds vary greatly between 0.5 MB/s and almost 10 MB/s. Every 5 seconds during the transfer the speed will drop to 0 KB/s, then the transfer speed will increase to 10 MB/s and then drop back to zero. The cache memory on the board should be absolutely negligible. Don't expect to frequently transfer files larger than a few hundred megabytes. If you need fast transfers, don't use them. *Update*: The seller contacted me to try and resolve my performance issues. I ran out of discs so the seller offered to delete my review in exchange for $5.59 instead. Haha.
