    I was pleasantly surprised by this USB thumb drive! It zips through data transfers like a champ, and the generous storage space saved the day for my files. Its pocket-friendly size is a game-changer for my on-the-go lifestyle, and I can't overlook how durable it feels. Just plug it in, and you're good to go – super user-friendly. Definitely my go-to for hassle-free portable storage!

    Bought this during a Sale they had at Best Buy. For 29.99, you can't beat this deal although in the future it may drop lower as more and more Storage Capacity for USB will become more available at higher price. it is a good reasonable size or more than enough for transferring or storing all your data folders or big size video games or something you save your work on constantly every day. It works fine and i have no problem with it. it does tend to get warm after leaving in the Port for long time. It is a nice that it can slide back and forth after using it. I do wished it had a cap to cover the Port to keep it free of debris or anything small to get in. Its compact and portable.

    This security key has proven to be an absolute workhorse for my homelab and core infrastructure needs. It's solid, physically robust, and provides essential security for my hypervisors and VMs (Dell 5070s, 7040). I've constantly flashed and tested it across differing Linux distros (Fedora, Debian, Ubuntu) and it holds up without fail. Its quality as a FIDO2/U2F device is Excellent. My only slight deduction is for the initial setup complexity. Getting it properly configured with some Linux kernels and certain applications (like SSH/GPG) requires a deeper dive and some patience. This isn't a plug-and-play setup for the average user, but for the enthusiast building a robust, secure environment, it’s unbeatable value and performance.

    I have to say this first. SanDisk is my favor storage device. I own numerous USB drives, SDSH, microSDSH cards drives in various capacity. When I saw the 128GB USB ad, I went and got one. This USB’s measurement is approximately 2 ¼ inches in length, ¾ inches in width and 3/8 inches thick retracted, ideal for a key chain which is what I attached it to. The USB drive can be use with USB 2.0 or 3.0. Transfer a 4.35GB video file from the dash cam using a USB 2.0 took 6 minutes 13.44 seconds. Transfer the same file using USB 3.0 took 4 minutes 31.51 seconds. After 6 hours of work, this 128 GB USB drive feels a slight warm on the casing. So far, it runs like a charm; definitely will get another one in the near future.

    Pros -128gb at your finger tip is just wonderful for data archivers like myself -Small and light -Fast Cons -Tends to run hot a bit. I guess that's due to the slim packaging design.
