So, I bought an SSD, plugged it into my SATA 3 port on my motherboard, installed all my programs, and have been using it for a couple months. The speed is very fast and a very noticeable difference from my old western digital black 7200rpm drive. I recently did a speed test using CrystalMark and ATTO, and noticed my sequential read/write is only about 300/240 MB/s, while the SSD says it goes up to 530/240 MB/s read/write.
1. Is this because I forgot to enable AHCI on my mobo?
2. If I want to change to AHCI, will it clear the disk?
3. What's the best way of switching if it clears the disk - Norton Ghost?
SSD - Samsung 840 - 250gb
MOBO - Gigabyte GA-P55A-UD4P
Thank you for your time!
EDIT: Is this the solution for switching modes after Windows 7 has been installed?
When the system is in IDE interface mode, the respective start values are:
- msahci's START value is "3"
- pciide's START value is "0"
When the system is in AHCI interface mode, the respective start values are:
- msahci's START value is "0"
- pciide's START value is "3"
2. Switch BIOS from to version you want to use.
Is this correct? Are there any other troubles I may run into? Also, for verification I checked and my values are the IDE ones.
