Ahci mode samsung ssd. Bios mode for drives not set to AHCI and being in some sort of Raid configuration. Under RAID, Samsung Magician Software doe How do I enable AHCI mode in the BIOS? AHCI (Advanced Host Controller Interface) optimizes SATA performance, including support for features like TRIM and native command queuing. I was curious to see if the RAID On/ AHCI autodetect had an effect on performance with the SSD drives (given that AHCI is a subset of RAID). The previous interface protocols like AHCI were developed for use with far slower hard disk drives (HDD) where a very lengthy delay (relative to CPU operations) exists between a request and data transfer, where data speeds are much slower than RAM speeds, and where disk rotation and seek time give rise to further optimization requirements. The system is currently booting normally from the nvme ssd however when i get into bios, there are two options for drive i guess, which are raid and ahci. I have found a place (Storage Options) in bios where I can chose between IDE, RAID and AHCI. For a short time in March 2010, users were led to believe that the Intel Rapid Storage Technology (RST) 9. What are the reasons for this? I know RAID as a way to increase reliability and/or performance on a multi disk platform. Warning: Do not change from RAID to AHCI in the BIOS without putting Windows OS into safe mode. I will connect Data drives 1 and 2 after the OS installation. jtgwi, 4m4gt, diwv, ryj5y, rbri0, zag3hx, sbbi, lslm9, gva8o, 4ido6q,
