    This is my go to brand for flash drives and this one was offered at a great price point for the amount of GB included. I use them for moving photos from my phone to my external hard drive through my laptop and this connected easily, transferred photos, and was ready to go for the next round. Transfers went quickly and efficiently.

    I use sticks daily... the ultra stick seems to be a solid piece of hardware... however my favorite still is the Extreme that I splurged on about a year back... 100 mb/s vs. 300 mb/s! But at the cost when I picked up the Ultra 128 @ $29.99 who could resist.

    Incredible, who believed 128GB in a memory stick in 2003 ! Almost 1000 times bigger than the memory Stick available in 2003 for approximativelly the same price. So what will we do in 2029 with 128 Tera bytes in a small USB drive ?

    SanDisk is a good brand for USB drives....it works just as intended, no issue.... I paid around $30 for a 128GB USB 3.0 drive, cant beat that... I only gave it 4 stars because of its design... it has that cheap feeling (which technically it is cheap)
