I want to buy a server that has a RAID 5 configuration. I just want to make sure I understand it fully.
If I get 5 drives that will be a Raid 5 correct? Do I need a 6th drive as a hot spare? I guess that only matters how quick I want to be back up right? If I have that hot spare, then it will instantly start rebuilding the data onto that drive when another drive fails...correct?
Also, if I get 5 30gb drives...does that mean i will have 150gb of disk space, or does it mean I will only have 30gb, and it just splits the info up on each drive?
I need about 150 gb of usable space....with my RAID5 configuration.
