Can anyone point me in the direction of a real-world performance comparison between a iMac 5k's internal SSD and an external one (ideally one on thunderbolt and one on usb)? Basically, I want to know how much performance I'd give up by buying a smaller built in SSD and putting most data on an external.
I guess ideally what I want is something like http://www.macworld.com/article/2039427/how-fast-is-usb-3-0-really-.html but for the iMac 5k (so including Thunderbolt 2) and with the internal drive included for comparison.
A comment asked what specific SSD models:
- Internal - Whatever Apple ships I guess
- External - Let's say a Samsung 850 EVO (http://thewirecutter.com/reviews/best-ssds).
But if the answer is literally 'there's no performance benefit to the disk being internal; that answers the real question (but I'd still love to see numbers).
http://www.newegg.com/global/au/Product/SingleProductReview.aspx?ReviewID=4066303 suggests that reviewer found a big gap between an SSD in that specific thunderbolt enclosure and the MacPro's internal PCIe SSD - Is that more likely a limitation of the case or disk inside it (in which case how can I base avoid that?), or would that be likely to apply in my case as well?
