A traditional volume is a volume that is contained by a single, dedicated, aggregate. It is tightly coupled with its containing aggregate. No other volumes can get their storage from this containing aggregate.
The only way to increase the size of a traditional volume is to add entire disks to its containing aggregate. You cannot decrease the size of a traditional volume. The smallest possible traditional volume uses all the space on two disks (for RAID4) or three disks (for RAID-DP).
Traditional volumes and their containing aggregates are always of type 32-bit. You cannot grow a traditional volume larger than 16 TB.
You cannot use SSDs to create a traditional volume.
