JMicron: AS-SSD Performance
Using the WD SiliconEdge-Blue Solid State Drive, sequential bandwidth speed and operational performance tests were conducted on the JMicron JMF612 SSD controller with AS-SSD Benchmark 1.4.3704:
JMicron JMF612 SSD Performance on ICH10 AHCI
JMicron JMF612 SSD Performance on ICH10 IDE
JMicron AS-SSD Benchmark Summary
Using AS-SSD Benchmark on the JMicron controller, the reported sequential speeds both heavily favored AHCI mode. Reported AHCI sequential read/write speeds: 238/180 MB/s. Reported IDE speeds: 218/155 MB/s.
4K single thread read tests were very similar between AHCI and IDE, however write tests marginally favored IDE mode. 4K 64-thread testing revealed that AHCI mode offered the best read performance, while the write performance leaned in the opposite direction toward IDE.
The JMicron JMF612 SSD controller offered mixed results, but the AS-SSD Benchmark tests generally conclude that AHCI mode prevails.
SATA Mode Recommendation: AHCI
