Using an NTFS formatted Corsair Nova V128 Solid State Drive, sequential bandwidth speed and operational performance tests were conducted on the Indilinx 'Eco' Barefoot SSD controller:
Indilinx "Eco" Barefoot SSD Performance on ICH10 AHCI
Indilinx "Eco" Barefoot SSD Performance on ICH10 IDE
Indilinx CrystalDiskMark Summary
CrystalDiskMark 3.0.0b reported sequential read speeds in favor of AHCI mode, however sequential write performance was virtually identical between the two SATA modes. Reported AHCI sequential read/write speeds: 250/174 MB/s. Reported IDE speeds: 232/174 MB/s.
512K tests indicate a marginal advantage for AHCI over IDE performance, and 4K performance follows the same trend.
4K tests with a queue depth of 32 produced similar write performance results, but the 4K QD32 read tests undoubtedly favored the Indilinx SSD controller in AHCI mode and reported nearly twice the performance.
SATA Mode Recommendation: AHCI
