Customer Ratings & Reviews

The SanDisk 128GB USB flash drive exceeded expectations. It operates on USB 3.0 which transfers large files very fast. It also includes Carbonite online backup. I am very satisfied with my purchase and I highly recommend this flash drive to anyone looking for a fast and reliable storage device.

SanDisk is my go to flash drive and Best Buy has great prices and they are in stock.

I use to keep my digital movies, since I've tried external and had bad luck with them.... breaking down.... this USB storage has plenty of space, easy to carry and use.... so good I bought 2 of them on sale for 16.49 aw piece... usual mark like 40 bucks... so great price as well

Works great. Easily portable and retractable. Easy to manage in computer files. Overall great item.

It’s always nice to have portable storage. Bought this just to have. Sale price was great and I won’t buy any other brand.

At 76 I had put off buying a new computer as long as possible for fear I couldn't make the change and would lose a ton of important information for me and my community. I encountered the most amazing group of young people who took time to walk me through the entire process. Thanks Best Buy Team.

Purchased this flash drive to back up some files on my computer. With 128gb theres a lot of room, so storing all of my photos without running out of room, was a relief. The san disk 3.0 is faster than the older version with the 2.0. Using this helped out with the transfer time with the bigger file sizes.

Easy to use, fast with good capacity. And performance.

Quality product at a great price. Plenty of storage

The 128Gb SanDisk usb 3.0 flash drive is of excellent quality construction workmanship and design. It is small, lightweight and fast. And it is reliable. It's utility includes all media types the consumer wishes to download and save from small jpeg format imaged to mpeg movies. It is an excellent buy at Best Buy todsy!

I love it. It is fast. It is small compact easy to use.

It's a flash drive, so is pretty generic, but it's got tons of storage for the size, very convenient, and connects via USB 3.0, meaning it has fast transfer speeds. If it's not on sale, it's probably not worth getting at full retail price, but when it's on sale for $20 or $30, it gets much more attractive.

Perfect for extra storage. My daughter is a college student and this product was a perfect fit for her to store all her assignments and to be able to transfer and pull up files from one location to another. This is a wonderful product and I highly recommend it.

Item worked perfectly. I needed to back my laptop and the price was reasonable!

I wanted something smaller than an external hard drive to store frequently referenced data files and this meets that need perfectly. We spent two weeks in Europe last year and it was easy to download all of our pictures from that trip to this flash drive. So far saving and opening files seems to be fairly quick.

I have been using SanDisk flash drives for several years and find them to be very reliable and secure. I like the option of the slider to protect the metal access area. These keep dropping in price while getting larger and larger capacity!

I used SanDisk - Ultra 128GB USB 3.0 Flash Drive - Black when I transferred all data from old tablet to my new one. Very fast compared to previous 2.0 usb and great space storage. I had a lot of videos and heavy files, really saving time. Very happy for this purchase, thank you Best Buy for the promotion!

Can't tell you how many of these I have brought to use for various tasks like : Data backup, bootables with utilities, Linux and Windows OS recovery bootables, Best use is still for file transfer between computers and devices. They also don't heat up allot like some other USB sticks which is certainly a plus for lifespan. I have some Sandisks that are well over a decade old with the data still perfectly intact. Performance is very good although large file transfers do tend to drop in speed as expected in any USB stick. All in all the Sandisks have been lifesavers for me when I need to transfer data in a hurry without the fuss of cables and large drives.

I got this on sale so the price was "right". This product has functioned without problems. However, write times are slow for a USB 3.0 Flash Drive. San Disk claims speeds of "up to 100 MB/sec" and "up to ten times faster than standard USB 2.0 drives". I tested this drive and a USB 2.0 drive using the same USB 3.0 port and same 3.72 GB of family photo and video files. This drive copied the files at an average 5.6 MB/sec and never exceeded 5.9. The USB 2.0 drive wrote the same 3.72 GB of files at an average 6.1 MB/sec. The computer was idle during both trials.

It’s fast and reliable it did what I need but it does come with the installation guide, also make sure you format it first
