Intel IOMeter Disk Response Time

The write response time varies by little among the controllers. The read response varies more. The same five controllers are on the losing side again, the ND3260 being three times worse than the leader GL819 with firmware 93.21. Note that the write access time is two times that of SD and SDHC cards if used in the same card-readers.

Intel IOMeter Random Read and Write

The five losers do not change, but this time it is the AU6362 with firmware 01.29 that is the best among them. The leaders are the GL819 (with firmware 93.21), AU6332 and AU6333. Note that the gap isn’t large and mostly occurs on large data blocks.

There are no definite leaders here, and the slow group isn’t far slower than the leaders.

Intel IOMeter Windows Vista ReadyBoost

As you could expect from the sequential read diagrams, all the controllers, except for the slow five, overtake the 2.5MB/s limit. Take note that the speeds are somewhat higher than with SD and SDHC cards.

There are no surprises at writing. There are only three controllers that don’t pass the test: IC1210, AU6362 (with firmware 01.26) and SanDisk USB.
