Hello Community,
I have a Kingston SE9 16GB Flash Drive (USB 2.0).
The problem with this flash drive is that when I try to write any file to the flash drive, its speed keeps fluctuating between 2 MB/s to 5 MB/s in a very strange manner.
for example, If I am to transfer a 1GB file to the flash drive, it would be about 10 MB/s in the beginning, then it would come down to 5 MB/s, then 2 MB/s. It would rise up again to 5 and then back to 2, stay there for a second and then repeat. It looks like it pushes 5 MB of data every second and then flush the cache again or something, thus taking time.
I am attaching a Pic to clarify it. It takes a lot of time in this way, way more than any other flash drive. See the small peaks indicating some high fluctuations.
1. I have tried turning on the Performance mode; same results. Is there any other way to increase cache or something?
2. and there is no option in BIOS to turn off legacy USB support feature off.
3. I have tried copying files with NTFS, FAT32; Windows 8.1,8, 7 - all the same.
4. Same performance across multiple computers.
Plugged into USB 2.0 and 3.0 ports, same results.
