limonchoms Posted June 18, 2022 Share Posted June 18, 2022 In my array hard disk the partition format is GPT: 4KiB-aligned, but the cache disk is MBR: 1MiB-aligned, can someone tell me the difference between 4k and 1m? Why can't the cache disk be 4k aligned? Quote Link to comment
Solution JorgeB Posted June 18, 2022 Solution Share Posted June 18, 2022 Any SSD, doesn't matter if it's in the array or in a pool, will be 1MiB aligned, this is done for performance and write amplification issues. Quote Link to comment
