Intel SRT on Raid5 Array Question

Hey all! Just finishing building my HTPC.
Here are my Specs:

Case: Silverstone Grandia GD06 HTPC Case
CPU: Intel Core i5-3570K
PSU: 750W
RAM: Corsair Vengence 16GB DDR3 1600
SSD: Samsung 840 120GB
HD: 3 x Western Digital Red 3TB

My goal is to have the 3 HDDs in a RAID5 on the Intel Chipset SATA slots along with the SSD. Obviously the OS will be on the SSD. Now I've heard plenty of good things about Intel Smart Response Technology. Is it beneficial to even do this, that way ~64GB of the SSD will be a cache for the "hot" files off of the HDDs RAID array. Or is it really just to much hassle for what it's worth.

Pro's, Cons?

Also I've read there is a very particular way of setting this up, and in some cases it actually hinders write speeds in a RAID5 array.

Any thought/info would be great!

Thanks, TSSPat.

  1. I use IRST, I'm not sure if you can actually accelerate an entire raid like you have mentioned.

    I use mine in a set-up of OS HDD is accelerated by the SSD. that's it.

    I have two other HDD in my system that run as normal.

    IRST is a great technology and I've noticed a huge difference in load times.
  2. From what I've read you can allocate a max of 64GB of a SSD to ISRT.
    My OS is already installed on the SSD with plenty of room left for a few Apps/Games/Etc plus the 64Gb ISRT.

    Therefore instead of filling the SSD up with a bunch of "cold" files that I will barely use I will have half of it allocated to cache the "hot" files I use the most off the HDD's.

    Does this sound right, or is it not really what the ISRT is meant for?
