It's too early to talk about reliability (but the old SanDisk flash drives - I have 5 different ones with active use work from 4 to 8 years without breaking). The speed of copying large files from HDD to USB 3.0 is approximately ~108 mb/s. (Does not fail - tried on a volume of more than 17Gb) Its pros: 64GB SanDisk Extreme Go, USB 3.1, SDCZ800-064G-G46 . Work speed. Characteristics correspond to the declared. Not very hot (compared to 64GB SanDisk Cruzer Ultra Flair, USB 3.0). Good (not small) case. Excellent opening/closing mechanism. Cons below: Initially formatted in exFAT (my far from old TV did not see it until it was formatted in NTFS).
