Nice USB storage choice. Ultra Fit 3.1.
||Posted .Owned for 3 weeks when reviewed.Just super upgrade for media storage. Had a previous aqusistion of PNY 128 GB about six years ago, the SanDisk 128 GB is very small in comparison. Option for file management with SanDisk software adds to ease of setup.

Lots of Memory in a little package!!!!!
||Posted .Owned for 3 weeks when reviewed.Love this little flash drive. Very low profile that doesn’t get it the way. You don’t even notice it’s there. I use it to free up memory on my MacBook Pro. Very simple to use, just plug and play. No need to format it. Wish I had bought more than one when it was on sale..... :-(

Extremely Fast, Portable, And Sleek
||Posted .Owned for less than 1 week when reviewed.When purchasing this on sale it is an extremely good value! I purchased this to use with my Nvidia Shield to run tons of emulators and games, especially Sega Dreamcast, and Nintendo Gamecube Games as these are pretty large in size. The load times are instant and the larger storage will allow me to even add a huge Sony Playstation library as well. The speeds I was getting was 147MBs read and 55Mbs write.

Plastic and no cap
||Posted .Owned for 1 week when reviewed.This Flash drive works fine but is flimsy compared to the older model. This has USB 3.1 but is all plastic, the old USB 3.0 model had metal for the USB. The old model came with a cap, this one does not.

Very fast, compact.
||Posted .Owned for 2 months when reviewed.This is a very fast drive. Own several other SanDisk as well as other brands and this on seems to be the fastest by far. The stick is short doesn't stick out very far. I always worry about accidentally hitting longer sticks and breaking something. If you use a laptop somewhere other than a desk this is a must have.

Says its faster
||Posted .They say 3.1 flash drives are faster than 3.0, so I bought one. It sits practically flush with the edge of my XPS 13 laptop so I don't have to remove it when put it in its sleeve. I use it to back up my important docs without having to drag out another external drive when I'm on the road. I hate having these documents on the cloud. One problem is that it heats up when it's doing heavy transfers. I had another small USB drive like this before and you really can't avoid it because there's nowhere for the generated heat to go. So I'll take it out right after and hold it between my fingers to dissipate the heat. For 128 GB, it's got enough memory for me to be just drop stuff on it at will.

Q: QuestionDoes this flash drive support 4K and HD movie and video storage, as well as high resolution pictures?
Asked by Anonymous.
- A:Answer File size and specifications dont have anything to do with compatibility. Its the size you gotta worry about. Yes this drive supports 4k, HD, high res, whatever other names you'd like to call it. If the flies are small enough this thing can fit 8k, 12k, 96k, its all just the files size that matters :)

Q: QuestionHas anyone tried using this in an Nvidia shield as storage? Did it work and if so how well did it perform?
Asked by Boomer.
- A:Answer I have a 2017 version of Nvidia shield TV. After formatting, this USB flash drive did not work for me. I experienced the remote disconnecting even though it was still paired. Performance lag was unacceptable. Everything was back to normal after removing the Ultra Fit USB Flash drive.

Q: QuestionThe main purpose of me purchasing this drive is to fast transfer videos from one computer to another. Can I trust this drive to transfer heavy videos (from premier pro) from one computer to another decently fast?
Asked by kty.
- A:Answer I benchmarked it at around 139 MB/s read and average of 50 MB/s write (between 35 and 70). This is pretty good for a thumb drive but I personally would recommend a portable SSD drive for your need with video such as the Sandisk Extreme Portable SSD. It is really designed for Photographers / videographers and will give you the speeds you desire. I have one in the 500 GB capacity that I use for my RAW photos and I get around 555 MB/s read and 494 MB/s write. You will also get extremely fast Random read/write operations as well. Not to mentioned it is ruggedized for the elements.
