5.0 out of 5 stars Bulletproof and reliable thumb drive
Reviewed in the United States on November 3, 2022
Verified Purchase
These thumb drives screw into a metal container - which is as close to a bulletproof housing as you are going to get. This makes them suitable for travel, even wilderness travel. They are not the cheapest or highest capacity drives out there, but I have several and have found them to be reliable. No need to get these if all you are doing is transferring files from one computer to another, but if you want to travel with them, or backup stuff for a long period of time, I recommend these as a good option.

If you're like me and kind of rough on things, this is a must buy. It is very well built. I was going to put it on my keyring but I didn't want to scratch it. I have no doubt that it could of took the abuse though. I use it almost daily to work on a project at the house and on the go on my laptop.

I wish it didn't look as good so I could put it on my keyring but I opened it up and decided I didn't want to get it scratched. That would be the only "bad" thing, if you can call it that, to say about it. That it looks too good.

Excellent unit I had the smaller 64GB version for 5+ years without issue or incident and upgraded to this model for added space. The lower cost over time for the product is the main reason for getting the upgrade. The drives when closed are great for keeping the device dry and rugged use. I have dropped the closed unit on multiple occasions and the use and function didn’t even notice.

While I read mixed reviews and recommendations about the read/write speed for exporting tracks out of Rekordbox, this thing is blazing fast. Are there slightly faster drives? Yes, but this will get the job done in a matter of seconds regardless. Let alone, the difference between this and a Sandisk Extreme Pro is unnoticeable when loading tracks on a controller/unit.

Reviewed in Canada on October 3, 2021

These are probably one of the best usb storage devices on the market. The only issue I have is that they are costly little buggers. They are clearly double the cost or more of similar products in the same category. I've ordered both the 128 Gb and the 256 Gb devices. Both are solid and reliable. I very much like the protection their covers afford when transporting from place to place. Full aluminum outer casings with rubber seals and fast transfer speeds while using. Now, if only Corsair could lower the cost a little - really?!
