SandForce: HD-Tune Speed
Although HD-Tune is a single-threaded application that cannot offer deep queue depth, it does offer a basic interpretation of linear bandwidth speed. Despite the limitations, we've included this test to provide an additional perspective into our research.
Using a clean and conditioned ADATA S599 Solid State Drive, bandwidth speed tests were conducted on the SandForce SF-1200 SSD controller using HD-Tune 4.01:
SandForce SF-1200 SSD Read Speed on ICH10 AHCI
SandForce SF-1200 SSD Read Speed on ICH10 IDE
SandForce Read Speed Summary
Average AHCI read speed: 183.6 MB/s. Average IDE read speed: 168.8 MB/s. Favored SATA controller interface for SandForce SSD read speeds: Intel ICH10 AHCI-Mode. In one of the very few time AHCI performance exceeds IDE-mode, the SandForce SF-1200 SSD processor offered better read speed and smoother transactions.
SandForce SF-1200 SSD Write Speed on ICH10 AHCI
SandForce SF-1200 SSD Write Speed on ICH10 IDE
SandForce Write Speed Summary
Average AHCI read speed: 192.2 MB/s. Average IDE read speed: 195.1 MB/s. Favored SATA controller interface for SandForce SSD write speeds: Intel ICH10 AHCI-Mode with a 1.1 MB/s advantage.
SandForce HD-Tune Summary
Unlike the Indilinx and JMicron controllers the SandForce SF-1200 prefers AHCI mode over IDE, even if it's only to a slight advantage. Read speeds favored AHCI mode by nearly 15 MB/s, while write performance delivered a 1.1 MB/s benefit to AHCI over IDE mode.
