So, would a 7200rpm drive with a 16mb cache "beat" a 10000rpm drive with an 8mb cache?Tedster said:speed. a 10000rpm drive will access files faster than a 7200 rpm drive, but in most cases the nanoseconds or second or two is hardly worth the difference in price or is noticable by the end user. What's better is a drive with bigger onboard cache. 16mb vs. 8mb
