So I'm debating between equipping something like the Sonnet Tempo card with an SSD from OWC - my current boot drive is from them, and I'm quite pleased with it. My question is between the less expensive Mercury Electra vs. Extreme Pro. Leaving aside the longer warranty on the Pro, the primary difference seems to be the handling of Incompressible Data, wherein the Pro is vastly faster. It mentions things like certain photography and video file formats, but I'm not a photo/video person. The use of this would probably be as a screaming fast boot and application drive - possibly as a scratch disk for some scientific computing that has an I/O bound step in it, but those would be either text or binary files. Does the Pro represent a meaningful speed boost for me, or is the Electra suited for what I'm looking to do?
