Answer to: 1TB SSD from the late 2013 Mac Pro or rMBP compatible?Yes, it is compatible. If you look on eBay you can get a 1TB genuine Apple Samsung "blade" style from a guy in South Korea for about half what you'll pay stateside. I've ordered two over the past month. One for my rMBP and one for my mid '13 iMac. Write speeds are around 950mbs and reads are around 875mbs. Much MUCH faster than the 128 GB sticks that came stock in both machines. They are confirmed Apple sticks and Trim is enabled in Yosemite. Super easy to drop in the rMBP, not so much in my iMac. But worth it when I was done.
Answer to: Add SSD to a Fusion drive iMacHow did this work out? I have a 3tb Fusion also and would like to just upgrade the 128gb flash side. Is this possible?
