You need to look at what you’re trying to achieve to fully answer your question.
Having your apps and your media / clips on the same drive is always going to be the slowest implementation unless you’re running a high-end SSD. By placing your media files onto a secondary drive, the I/O operations for starting your app and accessing your media will get separate I/O.
Even then, a single spindle (single disk) secondary disk will be your bottleneck as a single drive (unless you buy new model, 15K RPM drives) will limit your I/O potential to around 100MB/sec (80MB/sec on FW-800 and 45MB/sec on USB-2).
The further answer depends on your connectivity options. Does you MBP have Thunderbolt? If so, you have a world of options available to you once you attach something like ATTO’s Thunderlink SH1068 or a Sonnet Echo Express with ATTO’s H680. You can now connect multi-drive arrays that will really speed things up. For example, I connect my Retina MBP to a Sonnet EE Pro with the ATTO H680. This is then connected to a 2TB, 4 drive SSD striped array (4, 512GB Samsung 840 EVO) that provides over 800MB/sec of sustainable I/O to the system. With FCP X, Motion, After Effects and PPro running from the internal SSD and my media on the external SSD array, I’m hardly every (if at all) seeing the busy cursor and things render very quickly.
