Customer Ratings & Reviews

Large storage capacity, fast speeds, compact, wonderful!

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.

Very fast and simple to use. Excellent for price!!

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 was in a panic (out of town) to purchase a flash drive to save my cellphone pictures on. Best Buy was so helpful in finding what I need.

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.

Great drive to store large files. Fast loading as well.

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.

Needed a cordless phone in the loft area. Works great easy setup

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.

This flash drive is exactly what I wanted/needed to hold my artwork, which are large files. I have used ScanDisk for years. Love their products.

Great Price! It was more than enough, but I always go for more just in case.

Easy to use, right size for my data storage, thanks

Great value for amount of storage. Fits on a key ring with lanyard for safety. No complaints

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

I was looking for a 128 gig memory stick, and bought this, it works just fine. It cost me a lot less than a 128 MEG memory stick did about 20 years ago.

This 256GB thumb drive is a solid performer, and can store a reasonable amount of multi-media files and large data sets. The USB 3.0 standard provides fast data transfer rates. I highly recommend this product for a portable backup solution.

Not much to say about this product -- it does what is should: plug & play with no fuss, holds the stated capacity (minus the usual bit of overhead), easily slides in & out of its shell, useful activity light flashes when i/o is going on, decent performance, etc. Nothing to rave about, but a solid product & good value.

Lots of storage capacity in a flash drive. It’s much better than a hard drive since it fits into your pocket.

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.
