You toss data chunks across several drives when you configure RAID 5 and that spreads things evenly. I recall showing you once how parity bits get calculated on the fly. Each drive holds part of your files plus some extra info for checks. But the parity lets the system rebuild lost pieces if one drive dies suddenly. Or perhaps you notice the array keeps running without a hitch right after failure. Then you swap in a fresh drive and it reconstructs everything from the remaining ones. Also the process uses math on the fly to fill gaps without halting your work. I always tell folks like you to monitor those rebuilds closely because they stress the other drives hard. Now the whole setup tolerates exactly one failure at a time before trouble hits. You lose capacity on every drive for that parity storage though.
Perhaps the array hums along fine until you hit two simultaneous failures and then recovery turns messy fast. I have seen cases where you pull the bad drive quick and the rebuild finishes in hours depending on size. But slow rebuilds expose you to more risk during the window. Or maybe you add bigger drives later and the array expands without full downtime. Then you watch performance dip a bit during heavy writes because parity updates eat cycles. I think testing your setup often helps spot weak drives before they fail on you. You gain that redundancy without needing every drive duplicated like in other setups. Also the striping boosts read speeds which helps when you pull large files daily.
You mix the data blocks with parity across all drives so no single one holds everything. I found this balances load better than older methods you might try first. Perhaps heat builds up during long rebuilds and fans kick louder than usual. But you keep backups handy anyway since RAID alone never replaces them. Then the controller handles the math transparently so your apps never notice the hiccup. Or sometimes you upgrade firmware to speed those reconstructions noticeably. I suggest tracking error rates on each drive because early warnings save headaches later. You end up with solid protection for most daily crashes without extra hardware layers. Now the capacity calculation stays simple once you grasp the parity overhead.
