I'm new to SSDs. My BIOS is in RAID mode, which I'm assuming also enables AHCI. My SSD toolbox says I'm optimized and have the latest firmware as of this writing. I've followed all SSD optimizations listed here. My write performance is slow. What could I be doing wrong?
Jugding from the system spec's you have listed at the bottom of your post you do not have a very up to date computer and with using ddr2 memory and an old quad core cpu you are not going to get the highest read/write speeds of any SSD.
