Awesome. Thank you for posting it
Out of curiosity, if I install two SSD disks, it is possible to configure the OS to see it as one disk?
Since I dont have the 6.1 I can not answer that. However when you talk about Raid 0 you need to know the following:
There is Software Raid and then there is Hardware Raid. In the 5.1 Mac Pro World we have many options regarding that, such as Apple Raid card, Sonnettech raid SSD raid card, Caldigit and other third party raid soltions such as the Amfeltech Squid card SSD raid gen2 & 3.
Out of experience of some colleges, the Apple Raid card Hardware solution was always a pain and never really performed well. The sonnect tempo SSD raid card was good to my knowledge but was tricky with bootcamp. In the end I decided against any raid solution in my 5.1 MP and I just bought bigger SSD card solutions instead.
With a Raid system you defenitly add complexity to your system and the risk of technical failure will be larger. If you have mission critical stuff, I would not sleep well with a halve baked raid integration that is kind of skiddish.
When it comes to the two options mentioned above, I would probably stay away from the OWC solution because of the sandforce controller. OWC SSDs are known to fail often, compared to Samsung or other brands. There have been many posts on this forum regarding service issues and failed SSDs from OWC. The Amfeltch is for sure more expencive but it is three times more solid and majure. If you are a professional and you live from contracts where failure is an no go, absolutely go with the amfeltech soltuion. Thats what I would do..
It would be way better to weed out the attic & basement for ebay stuff to counter finance a solid solution, then go el cheapo on a sandforce controlled OWC SSD...
