I have a 2011 3.4 GHz i7 iMac w/ 16GB of RAM.
I have 2 1TB external HDD (MacAlly enclosures)- one for my data files and the other is for my TimeMachine.
Since I've had my iMac, I've always encountered the beach ball when opening MS Office files and data files on the external HDD.
I'm at a point where I'm getting fed up with the lagging and delay.
Are there any external SSDs or enclosures similar to what I have w/ my HDD? (Not for the TM backups, but for my drive that has data files.
FYI- I also have two monitors connected via Thunderbolt (total of 3 displays).
