    This was a huge upgrade for the 16GB flash drive that I bought a decade ago that was bigger and much slower. The USB 3.0 speeds are great and 128GB of storage that fits on a key chain is awesome!

    I have several of these throughout the years and really great to have. I had to clear out several older laptops with many pics and documents. This has no problem saving them. I have used small SD cards but finding more slots for this SanDisk than the smaller ones. I now have to go thru all of them to remove the repeats. The price is great from Best Buy, where I usually buy all tech.

    I bought it for speed (USB3.0) and the huge capacity...and it works great. can transfer lots of pictures and music very quickly - its over twice as fast as my USB 2.0 flash drives. Fast delivery and at a very good price - who could ask for more???

    I bought this USB flash drive for only one reason: installing windows. I was not expecting much, but the processing speeds are amazing for a 3.0 flash drive.

    Needed a bigger flash drive and this one fit the bill at a very affordable price. It is very fast and I have not had any problems with it. Next time there is another sale, I probably will buy another one....you always need more of these.

    Not as fast as I would have liked it to be, but I could not pass the deal I got at Best Buy $40 for 128G, so I got 2 of them. Still decent I/O speed, easily plugged and recognized on several laptops, and plenty of space to do backups.

    Since 128GB thumb drives have been at a price premium for the past year, it was nice to see this quality thumb drive on sale. It's USB 3.0 FAST and I use it as a bootable OS drive for best performance on a current USB 3.0 PC.

    This thumbdrive is great. Unlike other brands, my car USB reads everything (music) on it with no fuss. Lightweight, and the USB header fits snug in every USB socket. Love it!

    Sandisk - Ultra 128gb Usb 3.0 Flash Drive - Black

    The Sandisk - Ultra 128gb Usb 3.0 Flash Drive has been added to my arsenal of computer madness! And I'm saying this as a good thing. The value of this product was worth the purchase. The original price was staggering. So glad I got it at a reasonable price. But more importantly, I've never had a problem with Sandisk. As I continue writing my manuscripts, I love downloading them to this handy thumb drive. But my grandson said it works perfect for downloading from his latest version Play Station. (PS4? Whatever that means.) So far, I have not been disappointed with Sandisk. It's obvious I'm not an expert on technical matters but the Sandisk is easy for me to use, with the help of my PS4 expert.

    Jumping up from 32GB to 128GB is very cool. I use it everywhere: Laptop, work computer, and even the Roku. USB 3.0 is so fast. I think this memory stick is especially fast. I really love it.
