I am hoping it is OK to post to a year old thread but has anyone figured out compatibility between SSDs on the late 2013/early 2014 PCIe 2.0-based (faster speed?) Haswell models yet please?
Is that pricey OWC the only route or is there a compatibility chart somewhere and can I use the apparently available adapter in there to give me a range of options on the drive?
And in this instance, does incompatible (as well as non-backwards compatible) mean wont work or wwont run at the faster speeds PCIe 2.0 can manage? There seem to be a few adapters out there (eg the DeLOCK Konverter Blade-SSD (MacBook Air SSD) > SATA,
Adapter 62644), though none say they will work at the proper speed with the ME293LL/A - MacBookPro 11,2.
