Devices can be of different sizes. However, if one drive in a RAID configuration is bigger than the others, this extra space will not be used. Someboot loaderssuch asSyslinuxdo not support multi-device file systems. Btrfs does not automatically read from the fastest device, so mixing differen...
For example, a SSD drive can remap the blocks internally to a single copy--thus deduplicating them. This negates the purpose of increased redundancy and just wastes filesystem space without providing the expected level of redundancy. The duplicated data/metadata may still be useful to statisticall...

When you create partitions on a hard disk drive, you should be aware of the following two partition tables. MBR: Master Boot Record. GPT: GUID Partition Table. If you buy a new hard disk, it’s recommended to use the newerGPTformat to partition your hard disk. Both MBR and GPT will ...
Remove Volume1 by removing a drive at a time until the Synology decides it's "failed" and can be totally forgotten. As I removed a 2TB drive, I replace it with a 10TB and expanded the new Storage Pool and the Volume2. These expansions take time as there's a complete consistency chec...
