> 3 dayLike the large storage capacity. Outer plastic case cracked and now is broke. Still works but plastic case falls off. Metal would be better but probably would increase the manufacturing cost.

> 3 dayIt arrived slightly late, but that’s due to weather conditions so completely understandable; on the actual product: I love how it is very Small and Compact and doesn’t stick out of Xbox Series S too much. I have it formatted for Backward Compatible Xbox Games. It was easy to double my Xbox Storage from 512GB to 1TB. I very much recommend this for any Xbox Series S owner.

> 3 dayCapacity is great. Small profile is great. That claimed 130MB is read speed. Please note... write speeds state UP TO 15X over USB 2 speeds. Key words here are UP TO. I use this device to store flac music files for playback in my car. I have plugged this drive into USB 2, 3 & 3.1 ports for writing purposes. I have seen extremely marginal performance differences between USB 3 & 3.1 (fluctuates between 35 - 55 MB when writing anywhere from 200MB - 2GB at a time). On a USB 2 port I get speeds around 20 MB on average. I will post test results and adjust figures as needed later as I am going from memory at this point. On another point, the frame of this no longer appears to be made of metal. I would say it is made of some type of composite material. I believe this was done with a purpose on the manufacturer to alleviate the heat issues with the previous model (which I also own) While it still gets warm while writing, it no longer gets hot to the touch like the previous model did. The heat dissipates much quicker. Given that, I do worry about the longevity and duability of this device should it have to be used and plugged in frequently in many devices. Overall, it serves my purposes. Write speeds could be better and durability could be an issue. Hence, my reason for three stars. **********Edit********** I have included Crystalmark tests (1 @ 500MB in size for USB 2 & 3). I did 5 tests while having it plugged into a USB 3.1 gen 2 port (1 of each @ 500MB, 1GB, 2GB, 4GB & 8GB). Speeds start dropping down the larger the test file was. Speed breakdown for the images is as follows for those that were wondering: USB 2.0 image is the read speed of 40.22 & write speed of 17.01 USB 3.0 image is the read speed of 126.2 & write speed of 50.41 USB 3.1 gen 2 images are the remaining 5 images as well as the windows copying images Just for a test, I copied over an approximately 4GB video file to the drive via the USB 3.1 gen 2 port (see the windows copying images). At the halfway point of the file, the speed starts to drop off and never recovers. Looks like the video file maintained a good 64 MB until the halfway mark.

Greater than one weekBig storage on a tiny drive. I immediately bought a strap in the hope that it will keep me from losing it. Best use might be additional (backup) storage permanently installed in your computer.

> 3 dayNo issues with reliability, but I wish it would be bigger. Hard to handle as its so small. Otherwise a quality product.

> 3 dayNot sure if its normal, but this dongle heats a lot on files copy. Its also way smaller than it feels on the photos. So the best way to attach it to some key ring or something.

> 3 dayIts seems pretty good other than it wont work for the primary reason I bought it. I purchased the 512gb version for a MCU2 Tesla to store video from the dashcam and sentry systems. Unfortunately the information system will not recognize it even after trying multiple formats and other troubleshooting. I got a micro SD in an adapter to work fine, but not this USB drive. Seems to work great in my Linux and Windows based computers, just but the Linux system in the Tesla.

> 3 dayNo cap or cover for the product, if you put it in your pocket or in your laptop bag, whatever is floating around is going to be inside of it
