    wanted backup destination that was faster than network backups. at first, it completed in 2 hours but after a few weeks take 4-5 hours. write speeds 5mb - 35mb. reads 50-80mb. best part is the size. made in China :-( i bought a 256gb and found that was much better than the 128gb in read and write speeds. manufactured in Taiwan. I would strongly recommend 256gb over 128 if speed is important.

    This was a great buy for me. I needed extra storage space for my files and wanted something small and compact. I got what I wanted with this product. It was very compact, almost to the point where I couldn't find it when I put it down, haha. At 128 GB, it was a great space saver!!!

    I love these SanDisk Ultra flash drives for my lap top's. Only about a 1/8th of an inch sticks out, so if your laptop slides off you knee or whatever nothing sticking out to bend or break. Capacity is fantastic in such a small package! I have several, and never had one fail.

    Needed to add some storage to my Sega Genesis mini. Was looking for something small in physical size and they don't get much smaller than these. I did notice it can get a little warm when transferring a lot of data but hasn't been a problem.

    I leave it plugged into my laptop to keep large files off the hard drive. Its small size and large capacity combine for a convenient, semi-permanent addition to my laptop. I have not done any speed testing but it performs the duties for which it was purchased.

    This little guy doubles the total storage of my MacBook Air, and it barely protrudes from the side of the USB slot. I found it on sale for around $30, so even better. Store photos, videos, documents, whatever you want. Easy to access off of the icon on your desktop.

    I originally bought this for my Nvidia Shield without realizing that these mini drives are notorious for over-heating. So I switched it out to my laptop and it is working great! Fits well and no issues!

    I used this to create a Windows recovery drive for a computer that wound up just having a bad hard drive. I haven't bought a USB drive in probably 10 years so I had no idea they were even putting 128 GB on a low profile stick like this. Everything worked fine, the only reason for four stars instead of five is that it becomes pretty warm/nearly hot to the touch after use.

    I got this specifically for my Tesla Model 3 for dashcam and sentry mode usage. This definitely has plenty of space to save footage and very small to the point you forget it's there.

    Great price for a great performance. It is very small which it could be a great feature for most of the people but maybe a problem for some, since it could be easy to lose.

    Works great for recording from my Aluratek receiver. The small form factor makes it almost invisible. It is easy to move in and out and hasn't had any problems being recognized by either my computer, Sony DVD player or the other receivers I own.

    Using it to boot Ubuntu Linux from a USB key. It was easy to set up as a boot drive and has plenty of space for using the operating system. It takes up very little space and allows the USB Bluetooth dongle to work.
