Why it is preferred to create a table space on a partition other than the system partition?

• Easy roll-in and roll-out of data.
• Easier administration of large tables.
• Flexible index placement.
• Faster query processing.
• Table partitioning improves performance by eliminating large amounts of I/O.

to get the largest performance, that when Oracle system work on system partition, the other table space will be in hand and have the speed to read from other partition
