    Initial Thoughts are mixed...
    This is a re-write so the details will be different.I wanted to expand the space in my Raspberry Pi to support a few LXD containers. Currently I am running a 32GB and 64GB without any issue. So I picked up the 128GB units.When I insert them into my Mac to format all five units show 125GB of storage. That was the first flag of notice for me. The drive was formatted with the LiveOS image and it seemed to take a little bit of time. Nothing major but it was fine. I then inserted it in the Raspberry Pi and booted and the time it took to setup was way longer than expected. I ran commands to update the OS and it took a much longer time than expected. I then took a second flash drive and formatted it (I had flashed the LiveOS onto it already) with APFS and it errored out but the drive looked fine. I copied files onto the drive and it took a really long time. I flashed it again with APFS and it once again errored out and the copy took a really long time. I then flashed the drive with EX FAT and the files copied fine. I flashed it again with EX FAT and no error and files copied fine. I then flash the LiveOS onto the drive again and once again the performance declined on the second drive the same as the first drive.The random IO on the drive for LiveOS use is not good, but if you format it with the right format the drive does good with file copy / transfer performance.I came back and read other reviews and seen others have similar experience already with these drives in my use case scenario.Hopefully this helps someone before purchase to make the right decision based on their use case. Drive works great with EX FAT format and not so good with LiveOS usage to boot off a drive.The packaging the drives came in was weird also. They arrived in a unmarked box with a label identifying the drives and bubble wrap.

    4.0 out of 5 stars Didn't Last For Me
    Reviewed in the United States on August 20, 2023
    I bought this drive to use for music file storage in my car. I had to get it formatted correctly and get all of the files on there, but once it was set up it worked just fine... there were some minor problems that I attribute to a buggy infotainment system in the car and not to this flash drive. It worked fine for over a year. Now, keep in mind, this is leaving the flash drive plugged in inside the car all of the time, freezing cold weather, 100 degree hot weather, all of it. The only time it got unplugged from the car was when I was adding files to it. In the long run I maxed out the number of songs the car can recognize (about 10,000).

    A few months ago the infotainment system got confused and started showing up some playlists twice. I took the drive out to see if I could somehow reset whatever the car reads, but as it turns out there doesn't appear to be any kind of file the car writes on the drive (maybe it's stored internally on the car). In the process of taking the drive out, I cracked the plastic case around the contacts... ultimately I was afraid it would break off into a USB port so I took that part off entirely (see photo).

    Yesterday I decided that I would try reformatting the drive to see if that solved the problem. I copied all of the content off (which took a good 5-6 hours) and tried to reformat the drive, but apparently now Windows sees it as write protected and I can't make it writable again. I don't know whether that has something to do with the broken casing or not, but now it is no longer usable either in the computer or in the car.

    Maybe 20 months of that kind of constant use is a reasonable lifespan for a flash drive. I definitely wish I had gotten one with a metal casing instead of the plastic. I loved the form factor for what I needed, and it was reliable enough until I tried to reformat it. So take this review with a grain of salt - I'd consider my use case to be a fairly rigorous one. If you're considering a similar situation, I'm not sure I can recommend this specific drive (unless I buy a different one and it lasts even less time - in which case I'll come back here and eat my words!)

    Até o momento não tenho nada contra, funciona perfeitamente, só que essa invenção de USB 3.2 só um chamariz, meu PC é da DELL e 2 canecões frontais de 3.0 e os equipamentos acima de 2.0 funcionam com uma mínima velocidade acima, o que deveria ser ao menos 50% a mais, principalmente com essa capacidade e não é problema do pen-drive, pode até se do próprio PC. Para finalizar digo que estou satisfeito com o produto, não tanto com esperava mas valeu a pena a capacidade e a segurança dos dados.
