Average Bench: 13% (377th of 639)

Based on 11,062 user benchmarks.  Device: VID 0951 PID 1666 Model: Kingston DataTraveler 3.0

This is one of the Kingston's newest flash drives and yet another drive from Kingston with no claimed read or write speeds on the official documentation, not an encouraging sign (Kingston have since quoted Read/Write speeds of 40/10 MB/s). With a sequential write speed of 9.9 MB/s and a random write of 0.046 MB/s This drive is actually slower at writing than a lot of USB 2.0 drives, it's seriously dog slow. I really don't understand why Kingston have released a flash drive with specs like this but then I guess they didn't write the speed in the specs for a reason! There is no reason to buy this drive, as there are far better USB 3.0 flash drives out there for approximately the same money. Kingston's own DTR30 is a far better drive for an extra five pounds. If you really don't want to spend more than £10 then the Verbatim Store n Go V3 is better for the money. [Jun '13 USBFlashPro]

Terrible average bench

The Kingston DataTraveler 100 G3 USB 3.0 16GB averaged 86.9% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.


Avg. 4K Random Read Speed 6.93MB/s

Very good consistency

The range of scores (95th - 5th percentile) for the Kingston DataTraveler 100 G3 USB 3.0 16GB is just 18.6%. This is a relatively narrow range which indicates that the Kingston DataTraveler 100 G3 USB 3.0 16GB performs reasonably consistently under varying real world conditions.

Usability on a Mac is off the cart bad. It's as slow as a regular USB 2 drive or slower. It's nearly impossible to make a bootable Mac Install drive from one. Mount times are very long, like 1 minute. Unmount is just as long. Do not buy this drive.—Sep '14


The only thing going for this flash drive is the price. The write speed sucks. I have 2.0 Flash Drives that write faster than this Kingston. I used the freeware chkflsh (recommended) and I got a write speed of 8.38. Kingston should feel ashamed of that performance and calling this a 3.0. Not recommended unless your a buying it to download a file and give it away.—Jan '15

very slow - Wish I had checked hear. Bought two for transferring large media files and its painfully slow. Is definitely not a USB 3.0 standard. Terrible DO NOT BUY.

The speed/price ratio is pretty good. At this price range, it's full of cheap 2.0 usb drives.


Ridiculously slow. So slow I thought it was defective.—Sep '14

While copying smaller files (like a (15 kb) x 200) pendrive is ultra slow - 0b/s for about 1-2 sec for file. :/

Price is good, form factor looks good. Not the fastest but it gets the job done. —Sep '14

Scored it 8.6, 0.6 for the speed, 8.0 for the price


Purchased one of these because the price was good. It was so slow that I searched to see if others had same problem. Slower than USB 2.0 for writing, somewhat faster for reading but very slow for a USB 3.0 device.—Sep '14
