How to speed up a web server on a flash drive?

Question

Nginx

Good afternoon!
There is an internal web application written in Yii (php+mysql+apache). When working from a hard disk (openserver) - everything works quickly. The task was set so that the data files were not on the computer, but all this worked from a flash drive.
The openserver was replaced with nginx 1.4.7 + php 5.3.x, and the mysql database was replaced with sqlite3. The code has been rewritten. From the hard drive, everything began to work even faster.
When transferring the entire configuration to a flash drive and running the web server from the flash drive, the application itself runs very slowly. Affects the speed of reading / writing to a flash drive.
What can be tips to speed up the work of such a system?

Answer 1

Move everything related to disk I / O (sessions, caches, what else?) To memory. Disable logging to disk.

Answer 2

to buy a fast USB flash drive, just for flash drives, the difference in performance by several times gives a difference in price by several times.

Answer 3

If the task is to work reasonably fast on removable media (and not just on a flash drive), then maybe try an external ssd drive?
