Why each option
The maximum native storage for a tape library with 30 LTO2 tapes is approximately 6TB, as each LTO2 tape has a native capacity of 200GB.
LTO2 (Linear Tape-Open generation 2) tape cartridges have a native, uncompressed storage capacity of 200 GB per tape. With a tape library holding 30 such tapes, the total native storage capacity is calculated as 30 tapes * 200 GB/tape = 6000 GB, which is equivalent to 6 TB.
6MB is an extremely small capacity for modern storage tapes and is incorrect for LTO2.
6PB is an extremely large capacity, far exceeding the capabilities of 30 LTO2 tapes.
6GB is also an incorrect and significantly underestimated capacity for LTO2 tapes.
