    This SanDisk drive is very handy and convenient. For the price, it provides great value and it having USB 3.0 makes it very fast.

    I bought this for my grandson who has a Levano 256 gig solid state hard drive in his laptop. He likes to make video blogs and this will help him to offload items that he no longer wants to store on his hard drive. He has sent me an email thanking me for this easy to use and to carry flash drive.

    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.

    I have BU External drives, but I like simple, small, easy to use thumb-drives. SanDisk have always performed the best of any products for me and for years. Now with the larger faster TD it has been perfect. Only need one instead of three and it is noticeably faster.

    It's a thumb drive....all it needs to do is accept and keep data. I wanted to copy all my CD's (about 600 of them) in a lossless mode to fully utilize the 36 speaker stereo in my new vehicle. Pretty simple. But, if (like me) you initially went with a less expensive option from the world's leading on-line retailer you can learn a painful lesson....I though I would save a few $ by getting an off-brand. The off-brand WAS NOT 3.0 as advertised, needed to be reformatted (took literally 50 hours) and still failed. So I stepped up and bought this SanDisk product. It performed flawlessly. No issues...period. My lesson is learned.

    Amazing speeds if you’re trying to transfer files or even transfer most of a whole PC downloads/photos/files. Best micro usb I’ve bought. Also great value for what it is.

    Works great. The little button to slide the usb tab in and out can be harder to get to in some positions, but if you dont care about retracting it, who cares!

    Good memory stick. Plenty of space for storage. However, I have a similar one from SanDisk previously that failed. I hope this one will last. Because of its size, it is difficult to get the contents backed up in another drive.

    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.

    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.
