I am using a USB stick with a USB 2.0 port on my windows 10 machine, and I noticed that writing speed to usb device is very low, around 11-12 MB/s, despite the fact that usb 2.0 speeds can go up to 60 MB/s, and average speed of a usb stick should be around 30 MB/s.

I am using a USB stick with a USB 2.0 port on my windows 10 machine, usb 2.0 speeds can go up to 60 MB/s.

60MB/sec is rare though. 30 to 35MB/sec is a more realistic value. Most external harddisks (and those tend to be faster than pen drives) are in this speed range.

writing speed to usb device is very low, around 11-12 MB/s, average speed of a usb stick should be around 30 MB/s.

Uhm. No.

Focussing on pen drives (aka 'USB sticks') those vary wildly. I have several promo pen drives which manage 5MB/sec read and 3MB/sec write. The limit on this is a the cheap pen drive. not the USB protocol.

I also have 90MB/sec pendrives which actually reach 90MB when connected via eSATA, but drops to 30MB/sec read via USB (a throttle pen drive with dual interface). MOst of my pen drives have been selected for high speeds, and 30MB/sec really is not average. 30MB/sec is very high. 11-12 MB/s is in fact quite decent for an average USB pen drive.
