SanDisk 128GB Ultra Luxe USB 3.1 Gen 1 Flash Drive - SDCZ74-128G-G46, Black

Ya, read speed is fast, but nobody really cares about that. Write speed is slow, but I think that's really just based on usb 3.2; usb 3.0 is almost unusable for large writes. As the tech gets better write speeds will increase. It gets hot, but still works, and cools down quickly. For now, this is about as good as you can get.

Works great. Decent speeds.

Use it on Tesla Model Y, replacing the factory 128GB, Working flawlessly. It is not hot, just a little warm.

I have now bought a few of these and have had two of them stop working after a while due to heat.I use these as MP3 Music sticks plugged into my vehicles USB ports located in my console. It's not in a tight space but like any console it is closed. After a while my music will stop playing and the sticks are very warm. Once removed, cooled, and reseated, they work fine for a while. Its intermittent and happens in both of my USB ports so it's definitely not a connection. I have three other identical (same sixe, mfg, etc) sticks and have no issues.They never fail on my computer and other usages, and I love the size, capacity and speed so I kept the rating as a 4 star.

I am using them to record my out door camera videos, from more than a year. Before that I used them for storing and transferring data from different system. No issue so far. did not lose any data or faced any connection issue.

Alway a quality product

Excellent product ... Fast, durable, and nice looking ...

I bought the SanDisk 512GB Ultra Luxe USB 3.2 Gen 1 Flash Drive to replace a flash drive that, after several years of use, finally went bad.Pros and Cons:Pros:It's tiny and sleek, and the metal shell appears strong and sturdy. It can fit on a keychain and has a good amount of memory- 512GB. It's also a USB 3.2 Gen 1 version that is supposed to do transfers up to 400 mb/s.Cons:I just got the flash drive and plugged it into my 2020 Macbook Air M1, and after just 5 minutes, the drive was extremely hot to the touch. It's much hotter than other flash drives I've used. I tried to move 6.9GB of data over to the flash drive. Something that should have taken seconds but came back with a window that said it would take 13 hours. -WTH!!! I couldn't believe it, so I canceled the transfer and repeated to transfer it again, and it came back with the same window info. - 13 hrs. I decided to let it follow through with the transfer to see what would happen. After 8 minutes, I gave up. I unplugged the SanDisk flash drive and plugged in another flash drive (Patriot Rage XT 128GB USB 3.0) that I bought back in 2014. This time, the transfer took 43 seconds. I don't know why the SanDisk flash drive I bought was not performing correctly, but I returned it the next day to Amazon for a full refund. Lastly, I also had some difficulty plugging this SanDisk flash drive in and definitely had to put some extra strength into pulling it out. It was extremely tight-fitting compared to 2 other drives I have. I cannot recommend this specific SanDisk flash drive.
