Another great accessory for my Steam Deck!
5 Stars
Another great accessory for my Steam Deck!
Absolutely loving this sleek design of how the 2.0 USB is part of the housing itself.I have purchased this tiny yet powerful flash drive to transfer games into my Steam Deck that can only read type-C accessories.A quick note is the 2.0 port paint will eventually wear off with how many times you will be plugging in and out. Not a huge concern for me. But it may be a concern to someone else.128GB is enough for me to cut and paste, that’s why I went with the budget price (bought at: $16.78) which is astonishingly low compared to competitors.I’ve purchased it with my own, and I am definitely keeping it. I also recommend having a look at the higher storage that offers more storage space per dollar count.Hope this helps your purchase decision!👋

5.0 out of 5 stars Fast and Practical
Reviewed in the United States on October 21, 2023
Once SanDisk App is installed the drive works seamlessly and offers options of copying, moving or deleting files and other apps on the phone. Very fast. One gripe is the construction material is made of thin plastic, especially on the USB-A side, which does not seem to be all that durable. It's a fast and practical solution moving files between devices.
