You are about to be told one more time that you are America’s most valuable natural resource. Have you seen what they do to valuable natural resources?! Have you seen a strip mine? Have you seen a clear cut in the forest? Have you seen a polluted river? Don’t ever let them call you a valuable natural resource! They’re going to strip mine your soul. They’re going to clear cut your best thoughts for the sake of profit unless you learn to resist, because the profit system follows the path of least resistance and following the path of least resistance is what makes the river crooked!

Absolutely not. At those densities, the write speed isn’t high enough to trust to RAID 5 or 6, particularly on a new system with drives from the same manufacturing batch (which may fail around the same time). You’d be looking at a RAID 10 or even a variant with more than two drives per mirror. Regardless of RAID level, at least a couple should be reserved as hot spares as well.
EDIT: RAID 10 doesn’t necessarily rebuild any faster than RAID 5/6, but the write speed is relevant because it determines the total time to rebuild. That determines the likelihood that another drive in the array fails (more likely during a rebuild due to added drive stress). with RAID 10, it’s less likely the drive will be in the same span. Regardless, it’s always worth restating that RAID is no substitute for your 3-2-1 backups.
