Thank you for the reply.
I think you brought up the ESRT2 RAID - I've never heard of it.
Please refer to my initial post and these questions regarding a Matrix RAID:
Questions concerning a Matrix RAID
How does the system or the user discern when to employ one volume or another, when not to, or if there's any means of setting up rules, defaults, etc.
Is the user faced at every turn; whether installing an application or saving a file, to decide which volume type to use at that moment?

RAID can be very confusing. Almost like buying an auto. (compact, sports car, mini van, full size, pick-up)
Hauling concreate in a compact car is no fun
and comutting 60 miles to work in the pick-up at 10 MPG is not a good idea either.
The big question is what you are trying to achieve.
Speed, redundancy\reliability, or size.
Which type of RAID you create is will generate trade off between these parameters.
Raid basics 101:
Best: Hardware RAID - Raid is controlled by the hardware, has its own memory and battery back up and the CPU is not burdened
Better: Chipset Raid \ matrix raid - Controller on the mother board does most the RAID work, but CPU has some involvement
Good: Software Raid - OS does the Raid and all the work is done by the CPU.
(2 HDD system)
The basic 2 RAIDs are:
RAID 0: Pro: is a Mirror all the data is written to both HDD so nothing gets lost. CON: You only get 1/2 the total disk space since every thing is mirrored and write times are slightly slower than no raid.
RAID 1: or striped RAID -- PRO: 1/2 the info is written to each HDD so drive access is faster, space is nearly the same as 2 separate HDD. CON: Lose one drive and you lose all your data from both drives.
Going beyond 2 drives in the RAID 2-6 plus the hybrids RAID 7 - 30 gives you opportunity minimize the negative impacts or share the positive impacts.
If you want redundancy / Data security, you pay for it in total drive space abd to a lesser extent, speed.
If you want speed, the cost is drive space or redundancy.
3 or more drives in a RAID 5 or RAID 10 are what I normally see when people want the best of everything.
Once you create two RAID volumes, each one appears as a physical disk to OS. RAID level is transparent to OS - Windows doesn't know which one is RIAD 1 and which one is RAID 0. You can partition each volume just like you do on a physical hard disk. Let's say you'll have C: drive (RAID 1 volume) and D: drive (RAID 0 volume). It's your decision what to put on C: drive (normally OS, documents, photos, important data you don't want to lose) or D: drive (page files, games, movies, any data you can afford losing).
