EZITSOL 64GB Write Protect USB Flash Drive with Physical Switch, USB3.0 High/Fast Speed up to 150MB/S,MLC High Endurance Jump Drive Pendrive Thumb Drive Memory Stick

Write Protect switch.The switch works.I tested the Read Only (Write Protect) function of this flash drive.It does indeed work.On my linux laptop it would not allow changing the contents or reformatting unless unlocked.I couldn't override it in command line, or change its type or reformat with fdisk commands.It shows up as mounted in Read only format.But Be Warned DO NOT TRY to change the switch position while pluged into the USB port. In linux, at least, it will not work. But this is not a bad thing necessicarily.To change the switch FROM: Read Only TO: Read and Write. You have to unmount the drive and unplug it. Then plug it back in with the switch in R/W.It will work fine.Probably the same for Windows but I dont know.I can't test speed because my laptop is USB 2.0 but it does seem to max out USB 2.0.If I get a chance to test on other machine I will update the review.This type of function is only available on a hand full of flash drives.Other cost far more. "kangaruu"Or are unreliable. "I wont mention"I hope the speeds on a USB 3.0 computer will be just as shown.Thanks EZITSOL for not neglecting a forgotton segment of IT.David.

Great product for the money
