    Great item for the price, if you can get it on sale, but its a really small device so depending on your usb slot, it can be hard to pull out, and they don't include some kind of key chain to help remove the device from your computer. I don't have huge hands and im not a big guy but i still have problems pulling this thing out of the usb port.

    If you have a laptop needing a bit more storage AND a USB 3 port, this is very handy. Nice to keep installed all the time - doesn't snag on bags when you are on the go. Very easy to lose, so have a good place to put it when not in the port :)

    Great USB drive. It's perfect for my vehicle for playing music from, especially since it doesn't stick too much from the USB slot from the touchscreen.

    Works as advertised. Take note of the ultra fit part of the name though, they really mean it with the device - it is tiny and feels extremely fragile. I often think I will break it when I'm pulling it out from the USB socket.

    Poor performing drive

    I bought this to play music in my car, and wanted the small form factor so it would not be visible under the dash. Unfortunately, this USB 3.1 drive is substantially slower than my USB 3.0 drives, or even much older USB 2.0 drives. Writing my music library to the drive took about 2 hours. It is so slow, in fact, that my car can't read it quickly enough to recognize a USB is inserted. I have to wait about 30 seconds after start up, then manually select it, so it does not suit this purpose. By contrast, my USB 3.0 drives from Samsung or ADATA work perfectly and respond immediately. This was a relatively cheap drive. I would say "you get what you pay for," but the performance is so poor this drive seems like a poor value at any price. If you need a small form factor but don't care at all about read/write speeds, I guess this would be fine.

      Hi, please note that we do not recommend using any USB Drives/ Memory Cards other than the SanDisk®️ High Endurance/ MAX Endurance Memory Cards to be used with devices like Dashcams, Security/ Surveillance Devices, and In-Car Recording Devices as these devices perform constant read and write operations while recording continuous videos. Please use a SanDisk®️ High Endurance/ MAX Endurance Memory Card with a USB Memory Card Reader in your Car's USB port since these Memory Cards are specifically designed for constant Read/ Write Operations. You may purchase these Memory Cards from our official online store or from BestBuy. SanDiskConnections

    Straight out of the box and I knew that this was a high quality item. Sandisk is my go to for all portable memory solutions, and this was no exceltion. Write times are blazing fast when plugged into the correct type of port and so far I have had no problems.

    Using for extra space for my laptop. I Don’t nearly get the speeds it says it gets in the specifications. I do like how small the drive is. Doesn’t get in the way at all. Overall, I’m upset it’s a lot slower than what it says. I like how small it is. Would recommend getting something better.

      Hi, please be informed that the speed of a USB Drive depends upon various factors. This USB Drive does not have any published write speeds, however, it should provide you optimal speeds when connected to a USB 3.0/ 3.1 Interface. If you are not getting optimal speeds, you can contact us and we will perform a speed test on your USB Drive to check if it is performing within the expected specifications. We will check if your USB Drive is eligible for a possible replacement. I would suggest you to please contact SanDisk® support at 1-866-SANDISK or submit a support request at www.sandisk.com/support. We will isolate the issue and will assist you towards a resolution. SanDiskConnections
