Review on Sandisk Ultra Flash Drive SDCZ48 064G A46 by Bong Cha ᠌

I bought 10 flash drives to record a video file of 10 GB each. I was unpleasantly surprised by the speed of the memory. In fact, this is a slow USB 2.0. I first transferred a 10 GB file via usb 2.0 from the old computer to an external hard drive in 4 minutes (this is about 40 mb / s). And then I wrote a new computer to USB 3.0 flash drives in 13 minutes (which is about 12 mb / s). At the same time, using usb 2.0, the file recording lasted 18 minutes (about 9 mb / s) Conclusion: I would not recommend these drives to anyone, especially for personal use. It is 10 times slower than what is written on the package, and cannot even break through the USB 2.0 interface.
