  1. Mahi Reid

    I liked it very much, it fulfills what it promises.

  2. Fukumoto Shusake

    Good product, but It gets hot even without actual use.

  3. Rosalie Robertson

    Very good product, fulfills what it promises. It really heats up but as I’m going to use it just for storage I think I won’t have any problems. How much the reading and writing speeds here were lower than the product description, however, since my notebook has the 3.0 USB port, the product is 3.2 I believe its use will be limited. I finally passed Games to him that joining the 66,6GB taking 51 minutes to pass everything.

  4. Kholmatzhon Daniarov

    Well received. The product is excellent and well finished. The speed tested and of the writing Mo, 300Mo in reading (capacity 512go. A very good seller. I recommend buying.

  10. Antonio Levine

    Overall, OK, try it.

  11. Iside Casaletto

    The drive is of excellent build quality, the characteristics correspond to the specified. But there is a minus in the form of overheating: when transmitting data, the sensors indicate heating up to 70 degrees! Keep in mind. Delivery 2 weeks.

  12. Lorean Soni

    Ordered and paid on 10 January 2023. Received on 17 January 2023 in Singapore. Tested the card. It didn’t get too hot copy files over. This USB drive was inserted into a USB 3.1 port. Formatted to NTFS file format.

  13. Marlen Akhmetov

    Good SSD, ordered another one in stock. Some other revision, by name it is defined as kingfast, not UFD, plus the temperature sensor works on this revision. They didn’t put the thermal pad here when the sensor is 40-50 degrees-the case is cold. Speed decent

  14. Mammie Aguiniga

    I confess that when I saw the box I was afraid but the tests took away my doubt. Very good drive, beautiful design and fast.

  15. Andrea Xiong

    Exact description, first time I get a USB key with the exact speed as the description. I asked the seller for a particular service and he did it to me. I highly recommend the seller.

  16. Derrick Sclafani

    I’m thrilled with this! It has 500MB/s read speed. Fast enough to run virtual machines from.

  17. Emmanuel Gillie

    Just the right thing and it could be said that better than I thought the material, the aesthetic is quite good and the super fast delivery to Spain

  18. Sigmund Bruckmann

    Very fast key. best ever buy. Need Usb 3.1 minimum.

  19. Wendi Raver

    The order has been delivered. Tint flash drive, more precisely SSD.

  20. Xose Mendez

    Great product for file storage.

  21. Oscar Álvarez

    This is my second disc of the brand “kingfast”. The first was and is on 128 GB. This one on 256 GB. I use more than three weeks. Everything is fine, as with the previous one. Volume corresponds to. Recording speeds are pleasing (by USB 3.0 and USB 3.1 Gen 2). Heats up within acceptable limits. To transfer large amounts of data is what you need. The seller Thank you very much. Success in business and prosperity.

  22. Winston Hyde

    I will test disk. Please this is not fake.
