Customers are saying

Customers are delighted by the Ultra 128GB USB 3.0 Flash Drive's ample storage, fast speeds, and ease of use. The drive's USB 3.0 capability, convenient size, and large capacity are also appreciated. However, some customers have noted that the device can overheat during large file transfers, and a few would prefer a more appealing design.

    Decent USB

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I use the USB to transfer & watch movies on my TV. It does what I need it to but I didn't like the plastic design & the transfer speeds are slow. I also had to figure out how to format it for it to work. This USB gets really hot for some reason & sometimes worries me but it still works after having it for 3-4 years.

    Sandisk by far one of the most elegant and great design for their USB. Which is the main attraction when it comes to picking a USB .

    junk

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I bought usb 3.0 because it is supposed to be quite a bit faster than 2.0. guess that does not apply to sandisk. very disappointed in this drive. bought 2 of them and they do not write any faster than the 2.0 does. in fact, one of them was even slower than my 2.0 drives. and, yes, i had them in a usb 3.0 connector on my computer. I kept trying to write files to one of them and then tried the other. files would not write any faster than 15 - 18 mbs. very disappointing. last time I ever buy sandisk. these drives suck. for the list price you would think they would be better, guess that is why they were on sale for so cheap because that's what they are, cheap.

    Do not buy

    Bought this on black Friday for around $39.99. Now it is up to $100.00. Look at Walmart they have it way cheaper. The drive transferred around 52GB of music from my pc's 3.0 usb port. After an hour and a half it was done. The usb stick is said to have 128GB, after plugging it in only 116GB are actually available. DONT BUY.

    Died in under a month

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Purchased this for the sole purpose of keeping my graphic art safely on. Worked great until it didn't. With 12GBs of graphic designs it decided to just die one day; in under a month. So here I am looking to purchase another to only find the price has more than tripled since September! For the $37 I paid in September - it's worth a shot. But for the $119.99 (November, not even 2 fulls month) I wouldn't even consider it.

    This on sale and was a good price. It says fast and 128 gb but when i opened the packet and used in my laptop it was not like 3.0. It is really slow like 2.0. They said 128 gb but it has only 102 gb available.

    Honestly terrible. Slowest drive I own, and NOT intuitive at all to set up. I have never had an encrypted drive that was less intuitive than this. I'm trying to transfer a folder of 47 GB word files and .pdfs and it says over 5 hours to transfer.
