Review on Silamoom Waterproof 512GB Silver USB Flash Drive with Keychain – High-capacity Memory USB Stick for Protection On The Go by Jonathan Unruh

THESE PRODUCT SPECS STATE THAT IT IS A 512GB FLASH DRIVE, BUT IT IS NOT. THIS IS A 499GB/500GB FLASH. SEE ATTACHED PHOTO. My computer can read data from this flash memory at about 22 MB/s and write it to the hard disk at 6.037 MB/s. That's good! Despite the slight difference in marketing specs and real memory, I would recommend buying it!Update 2021.08.31: Flash memory is fake 512GB. I transferred 64GB of video files to this device and most of the videos won't play. I did it twice. I transfer my videos via network folder and all videos play fine. Do not buy!
