Hello all,
regarding to my introduction thread https://forums.freenas.org/index.php?threads/hello-freenas-community.46345/ I have some questions to the recommended drives.
My problem is, that I read RAID5/RaidZ1 is dead, because when you lost a drive and want to recreate the data with parity, the chance to get an URE is too damn high. For normal drives like the WD Red, we see a average of 10^-14, which regards mathematically in a failure of 100% with 4x4TB drives. I want to go with the 4x4TB drives in a RAID5, because I have a 1:1 backup of the files. But I see that the Seagate NAS HDD and the new Seagate IronWolf HDD with 4TB of capacity has only 10^-15 average of the not readable blocks.
So I would like to this about your thought. Do I need to go to RAID5/RAIDZ2 or are Seagte NAS drive more suitable for me?
Thanks in advance.
