SandForce: AS-SSD Performance
Using the ADATA S599 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:
SandForce SF-1200 SSD Performance on ICH10 AHCI
SandForce SF-1200 SSD Performance on ICH10 IDE
SandForce AS-SSD Benchmark Summary
Using AS-SSD Benchmark on the SandForce SF-1200 controller, the reported sequential speeds both heavily favored AHCI mode. Reported AHCI sequential read/write speeds: 206/94 MB/s. Reported IDE speeds: 157/68 MB/s.
4K single thread read and write tests were very similar, although they did lean slightly towards IDE mode. The 4K 64-thread tests undoubtedly favored AHCI mode on the SandForce SF-1200 SSD controller, reported AHCI read performance at 123 MB/s compared to only 22 MB/s for IDE.
SATA Mode Recommendation: AHCI
