>>1784669I really hate disagreeing with people on the internet, especially on such an overall polite board like /c/ so please just accept this as my own personal story and not a critique of your setup. Four years ago I had four 500GB drives in a RAID5. Unfortunately the array somehow became corrupted and all data became unrecoverable. Skip forward to present day and now a large part of my job is performing checks and maintenance on a server farm of over 3,000 webservers, most of which are running RAID10 (meaning every drive has another drive with an exact copy of all the data for those not aware). You would think RAID10 would be even more fail-proof but I don't remember the last time I went a whole week without having to restore an entire server from our NAS backups due to a failed array. The fact that I didn't have backups in my own case is unfortunately due to my own laziness and overall hatred for performing any computer work in my free time now that it's my job and I'm forced to do it 40 hours a week even when I don't want to.
I strongly urge you to at least back up stuff you doubt you could replace. It's a shame hard drives are super expensive right now since the flooding in Thailand closed half of the world's HDD manufacturing plants. As a result, a 2TB drive I bought for $80 three months ago is now $200. But I digress. To each his own. I wish you the best in keeping your data safe.
