When does ssd use write speed?

SSD reads a black of data at 200mbs+ but when does it write to it? Is it when you are installing the application?

Thanks

Windows is constantly writing to various files. My computer currently has 551 files opened with write access, in addition to the 1200 files open without write access. And I'm barely running anything. What makes an SSD so fast is the fact that it can write to any combination of these files with no loss of performance. An HDD will have to seek to all these locations which can result in noticable delays at pretty much any moment. Seek times run into the milliseconds, and can be greater than 10mS on many write accesses on a 5400 rpm drive. Stack up 20 or 30 of these seek operations in a row and you have yourself an annoying 1/3 second lag spike. But they can get much bigger than this.
