Using the WD SiliconEdge-Blue Solid State Drive, sequential bandwidth speed and operational performance tests were conducted on the JMicron JMF612 SSD controller:
JMicron JMF612 SSD Performance on ICH10 AHCI
JMicron JMF612 SSD Performance on ICH10 IDE
JMicron CrystalDiskMark Summary
CrystalDiskMark 3.0.0b reported sequential read speeds in favor of AHCI mode, however sequential write performance was very similar between the two SATA modes on the JMicron JMF612 SSD controller. Reported AHCI sequential read/write speeds: 241/188 MB/s. Reported IDE speeds: 228/187 MB/s.
512K read tests indicate a marginal advantage for AHCI over IDE performance, while 512K write performance was similar but managed to lean towards IDE mode. 4K read performance was comparable between SATA modes, while write performance slightly favored IDE mode.
4K tests with a queue depth of 32 produced nearly identical write performance results, but the 4K QD32 read tests favored the JMicron JMF612 SSD controller in AHCI mode.
SATA Mode Recommendation: AHCI
