Ok being a bootup freak i've done CF expermentation, as well as solid state drive experimentation.
CF was unstable at times, and I didn't like configuring HORM, and EWF.
SSD has fast boot, but slow read times (this affects hibernate resume).
So i tried this baby and BAM, fast EVERYTHING.
Startup - full XP 6 seconds from XP splash direct boot to roadrunner.
Hibernate resume is around 7-8 as well.
SSD was at least 10. I know the 3 second dif ain't much. but every little bit helps.
It's an awesome Mofo.
Highly reccomended.
