Internal 1TB Sata III for Macbook Pro 2011 (for the OptiBay, as a compleent to a Vertex 3 IOPS Max). Do they exist? If yes, what brand is it and what kind is are reviews like ?
from the above, I understand that no 1TB HDD is able to provide enough read/write speed to justify a 6Gb interface (or even3GB ?)
Not necessarily. A Velociraptor may fit, but it needs a 12V line which your laptop doesn't have. Normal 2.5" HDDs up to 9.5mm will work fine in the ODD space (and up to 12.7mm in the regular HDD spot).... My only option is to get a drive that fits the physical space... Am I right?
