    Not As Advertised
    Gave it 3 stars do to misleading/false advertising. San Disk Ultra USB 3.0 advertised as model (SDCZ48-128G-A46) but what you get is model (SDCZ48-128G-U46). One difference I found between the two is the A46 has a blinking light when the drive is in use and the U46 does not. I have several A46 flash drives and they all have a red or blue blinking light. This is what I thought I was buying. Not the U46. The last two San Disk Ultra USB 3.0 I purchased were advertised as A46. One was a 128G and the other was a 064G. I noticed the packaging (on the U46) comes with an added on white sticker that says NEW with a barcode that covers up the U46 model number but on the A46 there is no white sticker. I found them both to work equally other than one having the light and the other does not. I don’t know if there is a price difference. If so, I would think the drive with the light would cost a bit more. If so, you could be paying more for something you’re not getting with this purchase.

      5.0 out of 5 stars Solid Flash drive with no heat issues
      Reviewed in the United States on September 26, 2018
      Verified Purchase
      I ordered this drive, because the one I carry on a day-to-day basis was only 8gb and was full. It was the same brand. I ordered this 128gb, because the price was good and I didn't want to have to worry about space for quite a while. It's not supposed to house my life on it, just things I want quick access to, anywhere I go.

      I was slightly worried as I saw a lot of reviews saying this would potentially get very hot. However, this model did not. I've left in in my work PC all day with no ill effects and it didn't get hot even after transferring a lot of data to it.

      In case they mix reviews. This is the 'Sandisk Ultra USB Flash Drive, 128 GB, Black (SDCZ48-128G-A46)'

      Reviewed in the United States on April 9, 2017
      Verified Purchase
      Sometimes, technology can just astound me. In this case, I'm referring to my SanDisk Ultra 128GB flash drive. It came in the mail (a day early, no less) and I could hardly wait to put it to the test. It's literally smaller than my pinky, but has that HUGE capacity; I remember the days of floppy discs and this can hold as much as 120,000 or so of those. Wow.

      Anyhoo, time to put it to the test. I'm not incredibly meticulous when it comes to scientific method, but I transferred 62GB of files from an early model SDXC card to this new unit (on a 4 year-old ASUS G75VW) with an SD card reader and 4 USB 3.0 ports. It took about 26 minutes (I'm relying on memory here, since I didn't write this down). The flash drive got a bit warm, but everything transferred just fine.

      However, given its petite size, I will be getting a lanyard to decrease the possibility of losing it.

      *Works fine, so far no issues
      *Retractable tip, so no caps to lose

      This will not work on the nintendont gamecube emulator on the wii. This is not the drives fault as that software is picky, just letting you guys know. I did blast it with a 56GB transfer out of the box and it didnt get hot and the speed were good and consistent for the price. samsung is fast but more expensive, but not that much faster on the writes. maybe 20%. but its more than 20% more expensive. I own both and they both serve a purpose to me.
