![]() ![]() ![]() ![]() ZFS is slightly better for bitrot detection because CRC32 is far from being collision free.Īs far as I understand turning off checksums won't solve the non-ECC related issues with ZFS or BTRFS or any filesystem. As far as I remember SHA1 is around 8-10x slower than CRC32C and 2x slower than CRC32. If you have new SSDs with 10Gbps (1200MB/s) speed, then those can be bottlenecked a lot easier on ZFS because of the relative slow checksum algorithm. ZFS uses SHA1 and BTRFS uses CRC32C for checksums. you can use ZFS or BTRFS with non-ECC RAM if you save backup regularly and keeping the data completely bitrot free is not something critical. Server motherboards are great too, but had double or triple the price, which I could not afford.Īnother option to use BTRFS, but it is just as bad with non-ECC memory as ZFS e.g. It was almost the same price as a good regular motherboard and RAM. better to buy a workstation motherboard and ECC RAM instead. ![]()
