Kingston 128GB DataTraveler 100 G3 USB 3.0 100MB/s Read, 10MB/s Write (DT100G3/128GB)

Needed a larger capacity thumb drive to update software on UTV. Had no problem with it and my maps are up to date now.

I needed an additional USB drive to create a recovery boot USB for a new laptop. Saw this one on sale and didnt think twice (or read the reviews [my mistake]) because it was Kingston brand. Upon arrival, I knew something was fishy when formatting took longer than usual on this supposed USB 3.0/3.1 device. I started trying to move files of various sizes -- everything from small documents to lossy and lossless audio and uncompressed video -- and all of them wrote to the drive ABYSMALLY slow. I then decided to benchmark the drive using multiple tools, specifically CrystalDiskMark and SpeedOut. Imagine my surprise when both of them showed that this USB3 drive, on a USB3 port, was writing at less than a quarter speed of a 10 year old, USB 2 stick on the same port. Yes, LESS THAN A QUARTER of the speed. I could move an entire 3.7GB mp4 movie to the USB2 stick in the same time it would take to move an album worth of 320MP3 audio files to the *new*, 64gb USB3 stick. Knowing that Amazon has had issues with counterfeit items in the past, I ran another test to ensure the stick was genuine. To my dismay, it WAS genuine. Kingstons quality has clearly fallen a long way. Im not so sure a counterfeit wouldnt run BETTER. What a sad state of affairs. Not only is this stick unsuitable for its intended use as a system recovery device, its not even suitable for use as a backup device because it takes far too long to save anything beyond a few megabytes of size. Buy something else.

I have not had any problem with this and it has been about 2 years since I got it. Crazy thing I recently left it in my pocket and it went into the washing machine and dryer and it still works! Now I am not saying this is waterproof but I thought I lost all my documents and stuff. Non of the text documents were corrupted.

I was alarmed and surprised to read reviews about problems with thumb drives by almost all manufacturers. I had an old DataTraveler that performed just fine (as have a multitude of thumb drives in my possession) so I decided to give this one a try. Just fine for me. No issues.

A well-made product. Plastic is tough. It slides very well when opening and closing. It has the typical blue color of USB 3.0 inside. Excellent product, 100% recommended. Later I will see the speed of writing and reading data.

So far, no errors. Which is rather common in flash drives of all brand. Saving speed seems a little slow though, still reasonable.

Very convenient drive to use, but the drive comes formatted in FAT32, which limits the size of any single file you copy to the drive to 4GB. If you are using this drive with Windows 7, 8 or 10, you want to reformat it into NTFS before using it to remove that restriction. Very surprised that a modern (USB 3.0) flash drive would be formatted in such an archaic file system.

It does what I need it to do and doesnt disappoint in any way. Ideal for bootable Linux, since distros get updated frequently enough. (Side note: I realize that typical bootable Linuces require less than 8 GB. The 16 GB drives are actually cheaper than the 8 GB 1s. Go figure!) There are faster USB 3.0 thumb drives but the price blows anything else out of the water. No cap to lose either.

I wish I would have read the comments as I had only considered the price and the capacity. This drive is very slow, so slow that I had to verify the capacity with H2testw to verify that this wasnt an old counterfeit item. The test wrote to the drive at 30Mb/s or about 3 times faster than the USB 1.1 standard (about 6% of USB 2.0). It took OVER TWO HOURS to write 64MB to this drive, and the test passed.

I have used Kingston memory products for years and never experienced a failure. This flash drive in all capacities is an excellent buy for a USB 3.0, and is even cheaper than it was when I bought it about six months ago. Since I am always losing the covers on flash drives, the non-detachable cover is a huge plus for me. I think it may have a lifetime warranty like Kingstons memory sticks. Very fast even in a USB 2.0 port. I bought it to use as a dedicated OSX installation drive because an 8GB was unavailable. Now it is so cheap that buying it is a no-brainier if you want a fast, high-quality and heavily-constructed flash drive that will not die or lose your data.
