I've noticed that my fairly beefy PC slows to a damn crawl whenever disk usage peaks, often becoming intermittently unresponsive for several seconds at a time. So basically whenever I'm downloading something, installing something or dealing with a somewhat large file, things start chugging along. I've monitored hardware usage, and the only thing that's spiking is disk usage. The drive in question is an SSD though, so I thought read write speeds wouldn't have such a massive hit on performance.
So I'm wandering if it actually is the drive slowing things down, or is it possible something else is at play?
