AS SSD MB/s - IOPS / SiSoft Sandra

Patriot results are shown on the left side with the Crucial listed on the right.



The AS SSD benchmark measures sequential and 4K reads and writes, similar to CrystalDiskMark. It also tests access time, IOPS (input/output operations per second) and assigns a score rating for comparison. While blowing the Patriot away on bandwidth, IOPS and resulting score, the Crucial shows no advantage in access time. In fact the write access is significantly higher (slower).


SiSoft Sandra 2010 SP2 seems to confirm this, posting a .13ms access time for the Crucial drive, whereas the Patriot yields a .05ms in the same test. This is reflected in the Windows Experience Index for the drives, a 5.9 for the Crucial compared to the Patriot's 7.3 rating. Clearly something is amiss here; why is the Crucial apparently so much slower in access speeds, despite showing a commanding lead in bandwidth?
