If you find yourself wanting more you can go to a RAID setup (arguably unnecessary by most) or to a PCI bus mounted solution such as the NGFF N.2 format or a more direct method such as a PCIe slot.
Pretty much. Even high-end drives aren't typically worth it. A solid mid-range drive is generally enough. RAID and PCIe solutions (which are generally just RAID 0 SSDs) have stupid amounts of bandwidth available, but if you don't know whether or not you need it, then you probably don't need it. Same goes for RAM drives.
M.2 is PCIe and/or mSATA, by the way. Some drives can use both depending on the slot, and others are PCIe exclusive with two or four lanes available.

Not true. 840 EVOs and Pros can utilize RAPID mode, a RAM cache, that smashes SATA III in benchmarks. In the real world, nothing actually changes. The drives themselves, however, are bottlenecked by the SATA interface, and mSATA is just the standard SATA we know and love on 2.5" and 3.5" drives minimized for small form-factor systems. The connections are otherwise the same.
