Good read speed USB 3.0 over 100 [MB/s] But performed poorly on the write speed 27.76 [MB/s] SanDisk says the Ultra isn't optimized for write speed and you should get the extreme version but I didn't see that anywhere on the package.
This product is so misleading. Simply put, I feel duped by SanDisk. The advertised 100 MB/s speeds are accurate...but only for read speed. Read speed is only half the story. SanDisk, you cannot advertise this as 100 MB/s when the write speeds are at USB 2.0 quality. Do not buy this if you are expecting 100 MB/s, or even 30 MB/s, write speeds, because this drive will disappoint you at USB 2.0 speeds (10MB/s). The stellar reviews on Amazon made me hopeful, but turns out you can't expect too much from this flash drive. I have made sure all my drivers are installed correctly, so I know my computer's USB 3.0 capabilities are running, as can be seen in the high read speeds. Even my generic local computer shop's USB 3.0 flash drive had faster write speeds than this much more expensive drive.
This SanDisk Ultra USB 3.0 Flash Drive works exactly as you would expect it to. Transfers to and from the card seem to work quite quickly. The drive is about standard size, and like many others, has a slide button to slide the USB connector in and out. It also has a blue light that indicates readyness, and transfer activity. The drive is labeled in a way that makes it clear which side needs to be turned up for it to be inserted properly. (I hate drives that you have to try one way, and then the other, because you can't tell simply by looking at them which side should be turned up.) Finally, there is a molded, hole, in the curve at one end, to allow the drive to be carried on a key chain.The one negative I found, which is the reason this is a four-star and not a five-star review has to do with the software on the drive. There is an executable that I believe has to do with drive security. When I ran it, it recognized that there was an update for the program, downloaded the update, but then the update would not run.I paid full Amazon price for this flash drive. I wrote this review just to try to help others learn a little about it. I hope you found this review helpful. On the other hand, if you did not find this review helpful, I’d be interested in hearing why, so that I can attempt to edit it and make it more helpful to both you and others. If you leave a comment on the review, suggesting how it would be more helpful, I promise to respond to your comment, and to attempt to incorporate your suggestion in my review, if it is at all possible for me to do so. My goal is to write reviews that help people, as I have been helped by the reviews others have written. Thanks!

We will be happy to hear your thoughts
