    I got this to replace an old flash drive and my computer said 45 minutes to transfer everything from the old drive to this SanDisk and it was complete in under 5 minutes. I do not know if I was using a 2.0 or 3.0 port on my laptop but I was impressed.

    Bought this on sale to store temporary pictures for viewing in our tv after big vacations. Works perfectly. Don’t forget to format before using and choose NTFS for maximum space.

    Flash drive that does what it was intended to do. Only minor complaint is the push in/out mechanism which can be a bit of a struggle for big thumbs! Other than that keep on loading in my data!

    I bought this flash drive specifically to store thousands of photos as a backup to the folders on my computer. I talked to a sales associate in the store for a while about whether or not a should use a flash drive, DVDs , or an external hard drive. He was very helpful and knowledgable so after he informed me on everything I got this flash drive. It wasn't as fast as I thought it would be after he told me the difference between the 3.0 and 2.0 but I didn't mind too much since I'm just using it for long term storage.

    Good deal and great price. I was able to download all my files from old computer and keep them safe until the new computer arrived. Did not need to transfer all files because the flash drive was so large. I greatly appreciate the Best Buy prices for the many flash drives I have purchased. Thank you.

    For the price, this little guy can hold quite a large number of files, which works well for transferring large media files.

    I am aware of SanDisk products but nowhere to find one due to the version needed. I needed a 3.1 vice 3.0. Although it is not carried in the store, The representative was very helpful in getting it ordered for quick delivery. I really like SanDisk flash drives, very reliable.

    I bought this USB flash drive as on a deal of the day to use to store and archive family digital photos from several cameras. With 128 GB, it allows for quite a bit of storage capacity compared to other flash drives I had seen for similar pricing but with less storage capacity.

    I saved all my photos (proud mom/grandmom) and all of my machine embroidery designs on this flash drive. I have an external back up, but wanted extra security. And with this flash drive I can plug it into my other computer easily.
