Subject: Correct position for the internal dual SSD blades in MP7,1 ?

If the MP7,1 has two internal Apple installed SSD blades, and at some point are removed, is it important to place them back in their original locations ?

Thanks... :)

I wouldn't mess with them , knowing Apple's fetish for optimizing components in specific interfaces . If you lose the ability of those factory NAND package(s) to handshake with T2 , your Mac will no longer start up . It's where your boot ROM is after all . And if your Mac loses that handshake , it's off to the Apple Store for you .

By the way , not all MP7,1 have two NAND packages installed . Some , like mine , only have one ( 256 GB ) . The NAND packages also are interleaved , if there are two installed .

Yes, I'm aware some MP7,1s have a single SSD blade. My concern is that if a single SSD blade or the two SSD blades were to be removed for whatever reason, how important is it to place them back in their original locations ?

I've seen videos where the author has removed the SSD blades for allowing viewers' to see them, but they never replace them, so I'm wondering!

With all the processor experiments I made with my MP7,1 , I'm amazed it hasn't required servicing by Apple already . When something crucial doesn't pass an internal check with a hardware configuration , you get a Mac with a solid white activity light , consuming a steady 100 W or so at the wall and no usable HIDs .

If you want to experiment with this , just mark the two NAND packages with an unique name with a magic marker and install them in a reversed configuration . When you start her up again , hopefully it won't lock down your Mac 😗 . You're playing around with a security handshake , after all . Please let us know what happens !

... or reformat the SSD.
And I've told ppl a million times ... never , ever place data on a boot device. Just place the OS and apps there . If you lose those , it's relatively easy to recover .

Of course , every Mac these days comes from the factory with as many drives as you like , as long as your choice is "one ."

Place your data on some other drive and back up , back up and back up like tomorrow is WW3 .

By the way , I'm pretty certain optical discs will have a greater chance of surviving than other types of storage in an EMP event . So your archiving strategy should include plenty of shiny little discs ( especially Verbatim M-discs ) and ... cans of baked beans and bags of rice .

Anything magnetic is toast .

In addtion to redundant RAID, local mirrors, and cloud backups - I also backup to 2.5" USB drives and keep those in a safe deposit box at the bank downtown. There's a lot of steel around those drives, they'd probably survive any likely EMP.
