Using an NTFS formatted ADATA S599 Solid State Drive, bandwidth speed tests were conducted on the SandForce SF-1200 SSD controller:
SandForce SF-1200 SSD Performance on ICH10 AHCI
SandForce SF-1200 SSD Performance on ICH10 IDE
SandForce CrystalDiskMark Summary
CrystalDiskMark 3.0.0b reported sequential read and write speeds that heavily favored AHCI over IDE mode on the SandForce SF-1200 controller. Reported AHCI sequential read/write speeds: 211/90 MB/s. Reported IDE speeds: 167/70 MB/s.
512K read tests also indicate a substantial advantage for AHCI over IDE performance in both the 512K read and write tests. 4K performance was similar between SATA modes, although the results slightly favored IDE mode.
4K tests with a queue depth of 32 produced made a significant difference on the SandForce controller. 4K QD32 read tests favored AHCI mode with 115/82 over IDE mode with 20/66.
SATA Mode Recommendation: AHCI
