    I needed to expand my local redundant backup capability, and the flash drives I had were getting full! Convenient fit on a keyring, too.

    I save a lot of clips and pictures on my PS4. Recently I upgraded to the PS4 PRO but the space between the PS4 plates is too small for regular thumbsticks to fit. This flash drive is all thumb and no stick so it fits perfectly. The only problem is you need your (real) thumbnail to pull it out of the PS4 PRO. Otherwise, it is great.

    USB Drive works exactly as described, and bought the 128 GB when it is currently on sale. Great option to include Secure Access Vault if wanted to encrypt and protect important files.

    i got this for my ps4 as a back up for saves since i don't always have ps+ and only bought it since the flash drives i have don't fit into ps4pro due to the design compared to original. works really fast compared to my older 2.0 usb drives; only wish it was longer so i could take it out easier, have to use plyers

    Just by luck I found this small but heavy hitter of a flash drive for my laptop. 128GB and a USB 3.1 for the price was too overwhelming and I had to have it. I use it for everything now.

    This is a very tiny storage device. It can get hot if you transfer a lot of files to/from it, since it doesn't have much room for thermal radiators or anything. So just wait a minute after your transfer is done before touching it. I wish it had come with a small lanyard or keychain or something.

    purchased this on sale. I can say the size capacity for the price paid is fine, and the red speeds are tremendous, but the write speeds, I expected more when I found out it's write speeds average about 50 MBPS

This USB Drive does not have any published write speeds, however, it should provide you optimal speeds when connected to a USB 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 www.sandisk.com/support. We will isolate the issue and will assist you towards a resolution. SanDiskConnections
