    The flash drive is half again as large as my old hard drive. It's a miracle of technology that can put such capacity in a small component. It worked as soon as I plugged it in.

    This drive is great. It's held up for the two years I've had it for, and it works just as well. I love the huge storage capacity. There is one thing that bothers me about its physical design. Due to its slide-in-and-out design, it is difficult to keep the USB end extended when plugging it in. When you plug it in, you have to press pretty hard to hold it in place, so I'm always worried about damaging it. Other than that, a really good device.

    Incredible, who believed 128GB in a memory stick in 2003 ! 1 024 times bigger than my first memory Stick "USB PocketDisk version 1.2" bought approximately the same price 26€ ($30.42) in 2003 ! So 128 Tera bytes in 2029 for the same price ! but which version of the USB ?

    I bought this 128 GB USB 3 flash drive to store real time video from my Arlo Pro 2 cameras, 4 of them. It plugs into the Arlo Base Station. Even if the internet goes down, video is being recorded when motion is detected. I can then retrieve past events by ejection the the drive and plugging it into my iMac to review. Works great, I recommend it.

    128 GB in a small flash drive sounded so far fetched 10 years ago .. but now its here. Plenty of space for all my CAD drawings and PDFs. I keep my flash drive attached to my key chain when I'm out on a jobsites. Must have for everyone who don't have internet access everywhere they go.

    I'm pretty amazed at how much storage they're putting on these things now, and how the cost has come down. This is fast enough for sharing 30GB database dumps at work. I keep my mongo database on here and run it from the flash drive. The problem I have with it is the physical size. The case is rather wide, to the point that when I have it plugged into the macbook, I can't plug anything into the other USB port. I solved this problem by filing it down on the sides.

    SanDisk - Ultra 128GB USB 3.0 Flash Drive - Black

    I own this pen drive( SDCZ48-128G-A46) over a month, and have had no problems loading and reloading or with transferring files back to my computer. it's nice having a large capacity portable thumb drive. And works as advertised read speed (70~80MB/S on USB 3.0) . However, due to write speeds- a little slow (21~25MB/s on USB 3.0), and very slow on USB2.0 (7~11MB/s) I'd recommend for the people who are looking to essentially back-up their documents and transfer back to their computers at higher speed Read/write should look for San Disk Extreme Pro 128GB ( read speeds of up to 260 MB/s and write speeds of up to 240 MB/s )

    The SanDisk Flash Drive is a necessary item for the presentations which I give to educators and students. Most of my presentations are accompanied by a PowerPoint, which I save on the Flash Drive.

    The drive is very fast with reading and writing. The construction seems sturdy enough, though it doesn't compare to an all metal case. Overall a great product that I snagged for only $15! Very pleased
