    I ended up getting this flash drive during Black Friday and I could not be happier. I wasn't expecting to find this 128GB drive at this price but I could not pass it up. The drive is super fast (USB3) so all the file transfers are very quick. All in all, I am very pleased with the purchase.

    I bought this drive to consolidate the 4 others that I already had. It works great. No formatting issues. It may be a ltitle sensitive to unplugging without allowing windows to properly eject it first... I got it on sale for way less than you normally pay for a 64gb flash so it's even better!

    I needed to backup work files. I always need help with technical support and was able to find a customer service rep as soon as I walked into the Best Buy in Braintree MA. I explained what I needed and was presented with 3 options. What was recommended is what I purchased. It was a smooth process and my documents are all backed up. The stick allows me to keep my documents stored legally which is outstanding!

    I needed to clean my cell phone up and put my 3,500 pictures someone I trusted. This is exactly what I was looking for at a great price ( think I got it on sale) Large storage and easy to use. I have not put the videos yet so I'm not sure if that part is easy but it shouldn't be to different.

    The SanDisk 3.0 works so much faster at downloading large files compared to its 2.0 counterpart. Love the compact size. I have loaded up this flash drive with hundreds of photos, files and videos and it is no where near to its full capacity. Highly recommend.

    Was able to purchase the drive at a really reduced price, worked in the laptop and tablet, seemed to transfer files at the correct speeds, no bench marks made. Used as a disk image for a Win10 install as part of the back up prior to an update, have had no issues. Worked in both the 2 and 3.0 ports.

    I bought the Sandisk 128 GB flash drive because I needed to do some graphic design editing. It was perfect for my needs and came at a great price. Being a Sandisk brand it was my preferred brand for flash memory items. 128 GB was more than enough memory for what I was doing and it was fast enough at USB 3.0. The only thing it was missing was it wasn’t USB-C though currently it’s hard to find alot of computers having USB-C ports built in.

    I purchased the SanDisk 128 GB USB stick as a way yo store photos and music external of my Surface 2 Pro. It connects nicely via USB 3.0 and is easy to store in the pocket of the slip case I keep my Surface in. The 128 GB is likely all the extra storage I will ever need on this PC. So I am very satisfied.

    This Sandisk - Ultra 128gb Usb 3.0 Flash Drive - Black seemed like a steal at $24.99 so I had to pick it up. I was not disappointed. The transfers are as fast as advertised, and it's great only having to carry this around instead of an external HDD. Just keep you eye out for a sale!

    I purchased this when it was on sale for under $100 and I have gotten several uses out of it including using it as an image backup and bootable flash drive for doing a few hard drive swaps on my laptops. It is very fast when using USB 3.0. It was a good purchase.

    I found the SanDisk 128 GB USB 3.0 flash drive to be an excellent value at the price and storage offered. I use this to back up a couple of PCs and a portable PC and the ease of use and flexibility provide a sound alternative to backing everything up to an independent hard drive.

    I use this to clone my MacBook Pro hard drive for backups. Fast enough via USB 3.0 interface to work as a boot drive in a pinch. Also very battery friendly versus a platter drive and weighs next to nothing and fits in your pocket. When on sale, it's a fantastic deal.
