Internal vs External Raid0 and 5 cards

[Cyber Akuma]

Are you doing this just for a learning experience?
Six hard drives in one system is asking for trouble.

Building a new system, I understand I am going quite a bit overboard with it, but I have been stuck with very low-end systems for nearly two decades and for once want to have a very high-end build.

And its more 2 and 4 drives, rather than 6. Two SSDs in RAID0 and four HDDs in RAID5. Not like all 6 will be part of the same array. (My current desktop, which is a Pentium 3, has four IDE drives in it and runs fine..... well, as fine as a P3 system in 2012 can run).

Do you invision being being able to clone the Raid0 to the Raid5?

I plan to create backup disk images of the 0 on the RAID5, or just backup the irreplaceable files. I plan to store almost no irreplaceable data on the RAID0, it will just house my OS, apps, and games. The RAID5 will store my irreplaceable media (photos, home videos, documents, etc) as well as images of my disk software and other backups.

What really read/write intensive apps will you be running?

Its mostly to decrease loadtimes, although depending how much space I have left I might also use it for HD relatime video capture.

One reviewer of the $375 card noted that he got better RAID0 performance for his SSDs from the motherboard controller (ASUS board).

Hmm...... strange to hear. Most motherboard RAIDs use software for it, a dedicated card with it's own CPU should be able to far outperform it. Can a motherboard's built in RAID be bootable? I was told its hit-or-miss of you can boot from a motherboard's built in RAID features.
