There is this myth over the Freenas forums that ECC is a must-have for ZFS. If you read closely the posts that are supposed to prove this claim, they never give strong evidence that the pool losses are directly linked to the lack of ECC memory. It always ends up with cyberjoke stating that the issue was linked to lack of ECC. Moreover, One of the OpenZFS developers confirms this is a myth here : https://arstechnica.com/civis/viewtopic.php?f=2&t=1235679&p=26303271#p26303271 https://arstechnica.com/civis/viewtopic.php?f=2&t=1235679&p=... TL;DR: Zfs is as vulnerable as any other FS to bit flips. So if you care about your data, use ECC, regardless of your file system.
