I saw many post are talking about 3-6 drives, but i can't find a post that are talking about 100 10TB drives. I am trying to crate a 1PB drive in drive pool, is that mean I need an other 1PB drive pool for parity, or I set 100 drives as data drive at snap raid? If i set 100 drives as data drive at snap raid do i need a 1PB drive too or how big should the parity drive size be. Is there anyway to do software raid 5?(not windows raid5)

Hi, I am about to extending my pool with a new set of drives. In the past I moved from drive bender to this because 1 drive died / got stuck and I wanted to take advantage of the Scanner. So my current setup is a bunch of single disks and a RAID5 pool to prevent data loss of one drive, all added to one pool. I am now asking myself if it is still clever with drivepool and the scanner in place to build a second RAID5 drive with the new drives and add it to the pool or to keep it as a bunch of disks and rely on the scanner? Is there any advantage / disadvantage in using RAID5 for pooled drives or leaving them as a bunch of disks? I don't want to duplicate stuff, because this would lead to heavy requirements. At the moment I am at about 20TB for my media library and I don't want to double the required space With the new disks I would now be able to move the data off the RAID and reset them as a bunch of disks. This is why I am asking. Thank you in advance. Kind regs
