Wrong. ZFS' copies are made across several different devices.
- vladvasiliu 3y agoWhat do you mean? The discussion in this particular sub-thread is about running ZFS on a single drive (think laptop). Does it have some kind of mechanism to send the write for a copy "later enough" that it will likely end on a different physical block?
- poige 3y agoI meant "primarily this copies mechanism is targeted towards multiple devices setup". With a single SSD it's indeed prone to the caveat which was pointed out; even if not due to being mapped to same storage "area" but also because SSDs often fail completely. Also makes sense to note that __when__ narrowed to a single-disk setup ZFS' can be interchanged with Btrfs; almost same set of features but lesser overhead and complexity.
