When it comes to sequential transfer rates
, the Cheetah 18XL and Cheetah 36LP
post virtually identical results. Interestingly, however, the 18XL features a negligible but not insignificantly faster transfer rate in its innermost zone
, sliding by the 36LP by a 4% margin.
It's seek time that we're most interested in, however. Here the 18XL's optimized, reduced-weight actuator assembly allows it to power past the 36LP with an access time a whole... one-tenth of one millisecond less. Yes, that's right, the 18XL posts an average access time of 8.9 milliseconds compared to the 36LP's 9.0 milliseconds. Hmm... a 1% margin wasn't exactly what we expected. Are other differences between the two just as negligible? Let's find out!
