What are the USB 3.0 write speeds of these drives?

The specs say around 190MB/s. In my experience with it so far, that is about right.

I wrote a non-techie review of my 64g and 128g. I compared writing 37.3 gig of data - the San Disk disk took 5:55 minutes for the 64g and 5:50 for the 128g. The other 2 (not cheapies) took between 25 and 36 minites. All were done with the same source data on the same computer using the same USB3 port. They were all USB 3 drives. Not sure what the specs are, SanDisk has them on their website, but I can tell you it is faster than any of the others out there except maybe the Lexar and the price on those is much higher.

I only used it once. It showed the speed on a graph that fluctuated from the middle of the graph to near the bottom, slowest. It even stopped a couple of times.

Sorry, I haven't had a chance to try on USB 3.0, but, I know it's faster compared to my other WD Passport 2.0.

They would be limited to USB 2.0 speeds. Unless the USB 3 is not backwards compatible. Then wont work.

I wondered the same thing when I bought it since I wanted to be certain of this. The manufacturer said it was "compatible" with SATA III, but that does not necessarily mean anything. The external interface is USB 3.0 and limtied to 5Gbits/sec max throughput, of course. Anyway, after testing with a fast 3.5" 7200 disk drive, I came to the conclusion that the drive internally is running at max performance for its platter write speeds - as you can see from my reported review. Unless I were to check with an SSD, I would not be certain of the interface, but my educated guess is that it is is an internal SATA III interface ... hope that helps!

don't know all the specs on this drive but you can go to the sandisk web site to find out more

I believe the wrote speed is up to 90MB/s* and writes up to 60MB/s. Hope this helps.

It'll just be the USB 2.0 device that runs at the 2.0 speed. Your 3.0 devices will still run at 3.0 speeds. BUT take note of any bottleknecks! If your computer doesn't support 3.0 or you don't use a 3.0 port, you will not get 3.0 speeds! Also, something like transferring a file from a 2.0 ext HDD to a 3.0 ext HDD will only operate at 2.0 speeds max.

They do!5400 rpm drive to 5400rpm drive I get 65-75 Mb/s minimum using both ports.

Haven't tried large files, do not own a MAC, but noticed it writes slower than my older USB 3.0 drives.

Sorry, I have no idea. I can say that I am very satisfied with mine. It is fast and well built and did I say it is fast!! Works much faster than any thumb drives I own on 2.0 or 3.0

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

The Write speed was between 9.83 MB/s and 14.43 MB/sThe Read speed was between 64 MB/s and 78 MB/sI have the 16 gb and I used usbflashspeed for benchmark

Not sure I fully understand your question. The SanDisk Extreme USB 3.0 is a Flash Drive that plugs into and out of any USB port. If the port is 3.0, the transfer rate will be circa 10 X faster than a 2.0 Flash Drive. The Extreme model is the fastest. SanDisk sells an Ultra model too, found at Wally-World. And there is probably a Standard USB 3.0. The Extreme model writes at about 190MB/sec. All 3.0 Flash Drives are compatable with 2.0 USB ports on your computer.

Yes. A USB 3.0 flash drive will be faster than USB 2.0. Keep in mind however, that budget 3.0 flash drives are slower than more expensive 3.0 drives that have faster memory.

For hard drives, mine arrived with Toshiba DT drives at 7200rpm. They work exceptionally well and are slightly faster in my tests than other drives at the same rating.

If you are using an older machine that does not have USB 3.0 support the slower transfer rate can cause an issues such as this and there is no fix. If you are using a USB 3.0 port make sure your motherboard drivers and bois settings are up to date. After trying all this if the drive continues not to perform to your expectations I would exchange it for a different one.
