Prime Drives (PDs) are created by combining a Prime Key and Catalyst Drive. PDs have a max supply of 150. Their benefits are the following:

1. Receive a portion of PRIME flows from [Sink Redistributions](https://docs.echelon.io/echelon-prime-foundation/2.0-prime-token/2.2-sink-distributions).
2. Grant six (6) additional slots for [Keys](https://docs.echelon.io/echelon-prime-foundation/6.0-parallel-tcg-assets/keys) in Parallel TCG.
