I tested my SanDisk Extreme Pro 128 GB with CrystalDiskMark in Windows 7 (I have an Asus N76VZ notebook with 4 USB 3.0 ports) and here are the results (mine are on the right):
Then, I repeated the same test in the same notebook, but with Windows 8 (which was preinstalled), and… I was astonished:
In Windows 8, I could reach the full speed in writing and reading boasted by SanDisk.
After many researches, I couldn’t find an explanation for this. I’m inclined to think it could depend on the Intel drivers for USB 3.0 in Windows 7, while Windows 8 supports natively USB 3.0 and the drivers are Microsoft.
However, I tried the speed test with a netbook of mine (Acer Aspire One), with one USB 3.0 port and Windows 7, but AMD processor and USB drivers, and I got the same results of the Asus.
So, I can’t say if this could be a Windows 7 problem, instead.
To conclude, anyone can tell me if he can reach the full speed (more than 200 MB/s) with this flash drive in Windows 7?
Thanks in advance!
