64GB/128GB Write Protect USB Flash Drive with Physical Switch,Write Blocker Protection,64GB exFat USB3.0 High Speed up to 150MB/S,MLC Jump Drive Pendrive Thumb Drive Memory Stick

This is pretty much one of the best USB drives for those who do computer work and don't want sneaky viruses writing evil code to their USB drives in order to spread or if you stick your USB drive in a lot of public computers where viruses may lie in wait. Drive is also great for users who do not want their files accidentally deleted.Speeds:The drive is fine in both read and write speeds if you have a USB 3.0 Port. Did 2 speed tests on it and tested the write protect switch. It works like a charm! A mechanical switch ensures that it requires no software to use and that it will work no matter where you use it.

Slow, slow, slow. Read/write speed was so variable that the difference between the fastest and slowest sectors varied by more than a thousand times. (I have NO faith in the reliability of a drive with individual sectors that take over a second to write.) And, as a minor detail, the protective metal case the drive came in was dented.

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.

The write protect switch is small and subtle, but other than that it's a piece of cake to use this thing, and it's incredibly useful.I took some SANS classes that came with files for studying cybersecurity. Windows Defender will flag that stuff and quarantine or delete it in some cases, screwing up the collection of course files. With this, I can store the files write protected, so that they're safe from Defender or other endpoint protection systems, and without having to create unwanted exclusions in my security product.I would love to see an option with increased capacity but these are awesome.

Picture this: You’re in a dimly lit room, surrounded by computer screens, and you’ve got a mission. Your mission? Secure data transfer without breaking a sweat. Enter the EZITSOL USB drive, complete with its very own physical write-protect switch. It’s like the drive is whispering, “Bond, James Bond… but for files.”SuperSpeed, they say. Well, this little gadget zips through data like it’s outrunning an avalanche. Read speed? A whopping 150MB/S—faster than a caffeinated squirrel on roller skates. Write speed? A cool 80MB/S—it doesn’t break a sweat, unlike your stressed-out laptop fan during finals week.But wait, there’s more! The physical switch is the real star here. Set it to “Read-Only,” and suddenly your files are untouchable—like they’re wrapped in an invisible force field. Viruses? Malware? Accidental deletions? Nah, they bounce off like rubber bullets on Superman’s chest.And let’s talk endurance. This flash drive isn’t just a sprinter; it’s a marathon runner. Seriously, it’s the Usain Bolt of data storage.Plug and play? Absolutely! Pop it into any USB port, and voila! Data transfer magic happens. It’s compatible with Windows, Mac, and even that mysterious cousin - Linux. The default format is exFAT (for those 4GB+ files), but hey, you can always reformat to FAT32 if you’re feeling nostalgic.And the design? Sleek as a secret agent’s tuxedo. The aluminum alloy shell screams durability, while the mini size slips into your pocket like a stealthy ninja.So there you have it: the EZITSOL USB Flash Drive - a mix of James Bond gadgets and Olympic stamina. It won’t save the world, but it’ll keep your files safe while you sip your shaken-not-stirred coffee.*Disclaimer: No actual secret missions were conducted during this review.*

It is what it claims to be which is why I keep buying them (5). I wish it came with 128 GB or more of storage though. It's cost is reasonable considering it's benefits. I can use it on questional computers without fear of some unknown accessing and altering data. For storage I obviously use another USB Thumb Drive but for some permanent application (Linux multiboot operational systems) this Ezitsol is my go to and my Fav.

To my disappointment, after 3 months, I was not able to open any of saved file. This is very bad product.

I bought this to update the navigation on my Hyundai. Worked perfectly.
