I am not sure about Boot Camp, If I had to guess I would say it probably works fine but I have never tried it. Its def not faster than a NVMe enclosure or an internal SSD, but it is way easier than taking apart my 2013 iMac. A 2011 27" isn't too terrible to take apart, but booting SATA native vs using an enclosure is not much faster. Internal drive with an SSD would probably be around 400 R/W and one of the enclosures I posted gets about 300ish.Thanks for the suggestions, so the speed of these too are faster than your trebleet enclosure? So as i understand they do not need extra power supply to work, is that correct? And sorry to insist, but do you know if they support dual boot option (for mac os and Windows)? It is important for me to know. Will those speeds are better that the speeds on an internal ssd on the same imac mid 2011 27"?
