GA-Z68XP-UD4 | SSDs shown as IDE in BIOS, but running at SATA3 speed

<< < (2/2)

Myopic:
Thank you.

Do I understand correctly that the communication speed on the 6_GSATA3 and 7_GSATA3 ports emulated in IDE mode is similar to the speed on the 0_SATA3 and 1_SATA3 ports, which work in AHCI mode?

Myopic:
Using CrystalDiskMark, I tested the read and write speeds of two SSDs:
1) C: System, on port 0_SATA3 on Intel Z68 controller in AHCI mode,
2) E: Mine, on port 7_GSATA3 on Marvell controller in IDE emulation mode.

These tests show that the IDE emulation mode on the Marvell controller has significantly reduced read and write speeds.
