Question. Ive been reading about GPT and how it allows you to extend partitions past 2TB and 128 Primary partitions. This seem to be a Network related Feature, Similar to RAID 10; not necessary for a Home PC. Although I like the CRC feature that accompanies it. Now I have 3 320gb's in RAID 5, why?, for all the reasons you'd use RAID 5; as the Jr. version of RAID10. I am using my Home PC for Work applications and thats really the reason why RAID5 Instead of RAID 1.If you know about RAID I do not need to explain the benefits from 1 -5. if you dont read the RAID thread at a min. 1. now do i really need CRC w/ GPT if I'm running RAID 5. or is it a case of too much is never enough? 2.Also I'm looking partitioning the drives to have a place for programs, as my system drive is a 36gb Raptor? 3. Can I add disks in the future to the RAID?
