    We weren't pushed to purchase a flash drive to protect info on our much outdated laptop, but we felt comfortable when it was suggested that this inexpensive pice of equipment would make it a sure thing that we would retain all info!

    I am a professional photographer and video producer so I need to rely on devices that will transfer large amounts of data efficiently and without read/write errors. The SanDisk 128 gb thumb drives do just that. Not everyone has a high speed internet set up so these thumb drives are a value solution to large file transfer. The fact that they are affordably priced and available at Best Buy makes it all the better. I have purchased about 8 of these drives in the last year. The only thing I have to do is reformat to the proper file system that lets me transfer files larger than 4 gb. That happens simply and quickly. If SanDisk could make a way to label them on the outside, that would make them 5 stars instead of 4. Not a deal breaker, so buy them, you won't regret it.

    Do you know it's amazing how much data you can put on a thumb drive. If you want it a trusted product then you better pick up two or three of these little guys

    I needed to offload security image folders that were filling up main HD space, and this was a good option to move them off. It lets me clean off space without having to shuffle DVDs/CDs that would have been a pain. It is so much easier to cut and paste them to this storage. It is also more cost effective since it was on sale.

    These "SanDisk - Ultra 128GB USB 3.0 Flash Drive - Black" are great for data backups. The large size of 128GB and the speed of USB 3.0 makes backups of data easy and quick - just copy and paste, and done. This drive also comes with security software to protect your personal data from being accessed by prying eyes or being copied.

    New way to listen to my music in the car. My new car didn’t have a CD player in it. So I wasn’t sure how I was going to listen to my CDs while traveling. I just had to download those CDs and plug into my car. Unlimited music.

    128gb SanDisk drive - decent drive though I'm not crazy about the new shape that is a bit hard to grasp (undercut case, hard to grasp when using top 3.0 ports on my desktop. Same as a couple of 64gb SanDisks that I have. Loaded a bunch of movies on it to save HD space - works just great (as do the 64gb ones)

    I use it for photo and document storage. Keeps my stuff safe and forever. Sandisk products are the best. Good price from Best Buy, convenient store location. Online purchase and store pickup is great. Now they are doing curbside delivery. Thanks, Best Buy.
