Extremely Fast!! 405.8 read / 417.4 write
This 128 MB flash drive benchmarked 405.8 read / 417.4 write. System and results described in screen capturesMy Extreme Pro USB 3.1 / 128MB was 416.5 read but only 127.0 write using same benchmarking program (Gnome-Disks).The construction is all-plastic and doesn't feel as nice as the Extreme Pro.So durability and quality of material is not yet determined. We will have to see how it lasts. I am hopeful and happy with it so far!!12/17/23 update:. It survived a wash in my pants pocket. Still works fine! Your experience may vary!!

5.0 out of 5 stars Update: Working Better!
Reviewed in the United States on August 29, 2021
UPDATE: I originally said I was only getting half the rated speed from the drive. I couldn't figure out why writing to the drive was faster than reading. I decided that maybe it was corporate software installed on my system, so I repeated the CrystalDiskMark from my personal Laptop (Ivy Bridge era Thinkpad, Windows 10) and got much much faster speeds, both in reading and writing. I don't know if the tests are the same, but you can see a dramatic difference. It appears that the USB speed on my workstation is limited by the controller. I have updated my score to give it 5 stars.

Original Review
Received the 64 GB flash drive today. It states (on the 64 GB drive version) that read speed is 400 MB, sec. I'm getting 170 MB/sec maximum. Curiously, I'm getting 213 MB/sec max write speed. It is the fastest writing (not reading overall. It is faster with random reads)) flash drive I have, but it's half of the rated read speed. Writing being faster than reading is curious. Is it using some type of ram buffer on-board?

My computer (ThinkStation workstation running Windows 7) is USB 3.0 only (so theoretical max speed of 600 MB/sec). I have ensured it is plugged into a USB 3.0 port on the back of the machine. I've tested the drive empty and then after putting about 10 GB of files on it. With a 4 GB archive and a 4GB folder of about 1200 files, the transfer speeds were very fast (peaking above 200 MB / sec).

Considering that I'm using this on a workstation that isn't connected to the internet to transfer files, I can live with questionable durability. I need something that is fast that won't corrupt my data over about a 20 minute time period. But I'm sticking to my name-brand USB 3.0 drives for data that I want to carry around with me regularly. It's too suspicious that write speeds are greater than read speeds, and the read speed is less than half of advertised.
