bootit :
1. What do you think a RAID (of whatever type) will do for you?
Provide redundancy and speed. A hardware raid may reach up to 12
2. What do you use this system for?
Odd games but primarily wordprocessing alongside photo and data backups
3. What are the rest of the parts?
a raid 10 on RST with 4 old 1.5 GB seagate drives that takes too long to boot.
ASUS P8Z77-V Premium
i-3770K
Speed? A regular SATA III SSD will blow away a RAID 0 with spinning HDD's.
Redundancy? A RAID of any type does nothing for 'data protection', beyond physical drive fail. It does nothing for the far more common ways to lose your data.
Solution?
A 250GB or larger SATA III SSD to boot from, and a good backup routine.
No RAID needed.
