    Decent value for the price, however there are faster drives out there for a little bit more. The read access times are good, but write times were slower than average.

    I bought 2 of the SanDisk - Ultra Fit 128GB flash drives from laptops. Well worth the money. Small size so they don't get in the way. They are pretty fast very pleased. They are used in a laptop that has a small 64 gig SSD and I install programs and apps on them instead of installing them on the C drive. I have never had any problems with the SanDisk flash drives.

    The low profile design makes it near invisible. The storage to price point is unbeatable but the compromise is write speed and a little durability. It always gets very hot when in use and the smooth plastic loop makes it hard to pull out of the port. Lastly write speed is quite slow. it averages around 22 MB/s

    The speed in this little stick is incredible if you have a USB 3.0 or 3.1 slot to use with it. Even on USB 2.0 slots it still felt quicker than my other drives. I have no benchmarks to prove it, but that was my impression anyway. Still blows me away that so much storage space can be stuffed into such a small little flash drive. Downside is that if you have it full and it crashes or gets lost, that’s a lot of data to lose. Just a heads up to users that these devices should be considered temporary storage only for this reason. Keep backups on another device whenever possible!

    It does what any USB does. You know, store things. It's just small and low profile. Speeds are pretty good, since it runs through USB 3.1.

    I Have An Eternal SeaBiscuit 1 T GoFlex Storage Drive. Its never worked, backup anything or had proper software, I tried backing up media player music? It quadruppled each song on my puter? This little gem works seemlessly. I bought a 256 gig for my others files. Wish they had a reasonable 500 gig. I wouldn’t be looking at attached cloud storage. I hear you can’t move folders. I’m not moving 1,000’s of songs 1 at a time, I will die before I get done. If this storage situation doesn’t improve I’m going back to burning CD’s. I’m not paying $120 year for cloud stoarge.

    Low profile 128GB usb drive was the perfect storage solution for my Mixpre 6 ii (32bit float audio files). It’s small enough that it worked flawlessly with my sound recording set up and instantly backs up my files once I hit the stop button on my recorder

    It stores files. It’s fast and small, but it won’t mix my drinks or clean my house. Still, at the sale price I should have bought more.

    I got the 128gb on sale for $20 and everything about it is amazing. The speeds are great and I haven't had any problems with it yet. My only gripe is that fact that it is so small. The key chain hook on it is so tiny too that I cant fit anything in it! Im hoping to get a USB lanyard off amazon that will hopefully fix this problem. I loose stuff a lot and if you are someone who does too, I recommend a lanyard for it to put it on your key chain. At that point I also recommend a Tile or some other tracker, it really is helpful. But seriously this thing is TINY!

    I bought this usb memory stick for my daughter’s computer animation needs. Great value for the price, plenty of memory. But it is small. Tiny. Afraid she was going to lose it I wanted to attach something to it. The open end is so small and the way it is designed I couldn’t fit a variety of key chain rings, and other hooks.. they were too big. Had to use a safety pin and then attach something larger to that. Maybe a thin lanyard would work but not sure why it’s not designed to easily attach something to it so you don’t lose it when you take it out of the port.

    This 128GB Sandisk USB 3.1 flash drive is nice and small, though can sometimes be too small. When it's plugged in, it's pretty flush to the device. So pulling it out requires a specific angle for you to pull it out. I had trouble at first trying to unplug it, but when I figured out the correct angle, it has been easy every time. I love this flash drive! It is so fast and has a ton of space to hold what I need. I'd definitely recommend it for anyone needing a bunch of space and the speed to move files.

    Very substantial storage in a very small form factor. I have purchased several of these as back-ups and also to share a large amount of photo data with family members. I also use these in my car's USB port to store a large number of CD's in lossless format. Plenty of capacity for well over 100 CD's.

    Perfect little storage device for router media sharing or security camera storage. We use it in to store our security camera video footage and it works like a charm. Small and does not protrude far from the slot like other USB storage devices.

    I bought one of these about a week ago. I was so impressed by the speed increase of USB 3.1 vs. USB 2.0 that I had to buy two more as I now find the older USBs intolerably slow. This and it's about 1/4 or 1/3 of the size of any of the previous USB drives that I've owned. My only concern thus far is, they are so small, and all look the same, I'm not sure how I'll mark them so that I can tell which is which.
