About the SRT...I've read many people complain that it doesnt work worth a crap?
Odd. When I used it on my Z68 board before "paying a fortune for large SSD drive," it worked flawlessly. The reason I bought a big SSD was because the SRT function worked so well....it really sped up the system very nicely. But, since I had some spare cash, I decided to go ahead and just move to a full SSD hd for my OS and crap.
The small 40GB Intel SSD I was using for SRT is now in my wife's computer and still working well....wife loves how fast it's sped up her system.
As for it not working well, the problem is that SRT is certainly NOT a plug-n-play setup. It does require specific steps in installation that if not followed in order can and will cause it to either not work at all or work badly.
First, your onboard SATA controller has to be configured to RAID in the BOIS, not AHCI. While AHCI is a subset included within RAID, one cannot simply change the controller from AHCI to RAID and still have a working system. The vast majority of complaints I've seen revolving around SRT is that users stupidly just change the SATA controller setting from AHCI to RAID in the mb's BIOS and then are faced with a system that won't boot.
Done correctly.....SATA controller configured to RAID, fresh OS install on hd connected to that controller, Intel SRT software installed, then add the small SSD to the system---the last step.....it works very, very well. Definitely does speed up the OS boot time and app load times.
But realize, the small SSD only holds so much data, so if you use a lot of different programs a lot of the time, some will be pushed off the SSD cache drive and they'll act like they've never been on the SSD when you try to access them again. For this sort of user, a large SSD dedicated to the OS and programs is the only option that makes sense.
But for someone who uses just a few programs routinely, those will reside on the SSD cache drive for a long time, until it fills up with cached programs and needs the space. My wife's the perfect candidate for SRT as she has routine programs......the OS and web browser of course, Word, Publisher, and Excel, Photoshop, and 4-5 puzzle/mystery type games she plays. That's about the extent of her programs she runs, all fit nicely on that 40GB cache SSD she has.
So, SRT does work and work well. It's mostly people without a clue who are having the most problems. Hard to convert an existing system over to using SRT, but for a fresh install, follow Intel's instructions and it'll work like a champ.
