I am thinking of getting an external SSD for use as my boot disk and then connecting it via Thunderbolt. Presently I have a 72rpm HDD and it's showing it's age, but it's 1TB and so will the external SSD, the move is purely for speed, on top of this I have an external 1TB HDD which I interface via tryst ol' USB2 and use that for TimeMachine back-up.
My question is whether to cut the chord with the external USB 2 HDD and use the internal HDD as a TimeMachine instead when running from SSD?
Either than or keep the external HDD as a TimeMachine back-up and use a RAID configuration so that if anything were to happen I could pickup from where I left off, but not sure about the performance hit, or if I could even do that (i.e. RAID from external Thunderbolt SSD to internal iMac HDD)?
There is another option and that would be that the Thunderbolt connected enclosure will have two bays and so I could fit in an affordable HDD for one of these suggestions. The benefit being that I would be able to forfeit one of the mains plugs (1TB is never going to be Bus driven!) and use it for the Thunderbolt enclosure.
I suppose my main concerns would be how to set up RAID with the different storage systems and if it would work, as well as the performance hit, I'm not sure what suffers when connecting SSD to HDD and having a real time backup system, if it's even worth it? I am making the SSD move for speed after all. I may also consider encrypting my backup or RAID drive, something else that could affect performance..
