There was a problem filtering reviews right now. Please try again later.
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!
Last year I had bought a new laptop with a USB 3.0 port in it. I was so excited when I read that the 3.0 port was compatible with my 2.0 flash drives. I was ignorant to the fact that while the USB 2.0 drive would work fine in the 3.0 port, there would be no improvement in transfer speeds. Once again I was bummed.
I found this flash drive on Amazon for a really good price and again I was excited. I thought there would be a noticeable improvement in transfer speed, but to be honest, I thought it would be minimal (again, my ignorance).
When it arrived, I plugged this sucker in to transfer a movie and BAM! I was shocked at the difference in transfer speeds. I don't think I could ever go back to using USB 2.0.
The file access gui is clunky and antiquated. Windows has provided a decent file access gui for some time now. This one looks like it was invented right after DOS went away and doesn't provide much functionality.
I am not happy with this device and will return i. There must be some better programming staff working for these companies . San Disk is not one of them.
I'd request refund. How can I return this product?
