This isn’t default? Jesus. So I recently discovered the wonders of AHCI and decided to look at how my Toad-2009 machine was set up.  Sure enough, IDE.  My wonderful Intel SSD drive was fast and could copy the WinSXS directory onto itself at 30MB/sec.  Switching the bios to AHCI however changed that to 50MB/sec. 

So for 2 years, I’ve been getting half the drive performance I could have been getting because the PC manufacturers still default to IDE.  Heck, why stop there? Why not use MFM or something too “just to be safe”.

Grrr.
