That article makes claims of 25% reduction in perf with no data to back it up, then mentions fragmention leads to system instability, requiring reboots... What? Again no data given to back up these claims. It's also SAN/Enterprise-centric. Even if you lost 25% perf, you're going from 200,000 IOPs/sec to 150,000 IOPs/sec. This is still plenty fast.
