Is AHCI required for SSD?
AHCI mode as previously explained enables NCQ (native command queuing) which is really not required for SSDs as they do not need optimizing in this way as there is no physical movement of heads or platters. In many cases, it can actually hinder SSD performance, and even reduce the lifetime of your SSD.
Is AHCI faster than IDE?
But AHCI is considerably faster than IDE, which is an older niche technology for outdated computer systems. AHCI do not compete with RAID, which provides redundancy and data protection on SATA drives using AHCI interconnects. In fact, enabling RAID on Intel motherboards enables AHCI as well.
