Hello all, My mid-2011 iMac has become quite sluggish so I'd like to add an external SSD drive and utilize it as a boot drive for increased speed. I realize adding one internally would be much, much better, but I'm adverse to opening up my iMac. As its a mid-2011 model, the usb ports are all 2.0. I currently have a Kanex thunderbolt to usb 3 and esata adapter and have a usb hub connected to that with three external hard drives connected to the hub. I'm looking at two options (although I'm open to other suggestions): Transcend 256GB SSD Thunderbolt - attached to the second, open Thunderbolt port. ($160) or Samsung T3 Portable 250GB SSD USB 3.0 - attached to the USB hub which is attached via Kanex adapter to a Thunderbolt port. ($105) Will I see a decrease in speed if I choose the Samsung as it would be connected, along with other drives, to a hub and through an adapter? Thank you!
