    Hi,
    I currently have 4 x 4TB drives in my MacPro3,1 2008 8core 2.8mhz

    I'd like to put 8TB or 10TB drives in but OWC told me that the screw holes on the bigger capacity drives have changed location and my MacPro drive sleds wont work.

    Has anyone found drive sleds/brackets which will work in the MacPro3,1 and hold those 8 or 10Tb drives?

    I see sleds for Mac Pro (2009-2012) https://eshop.macsales.com/item/OWC/MPRODBKTLG6/ but they dont make them for my 2008 macpro so I wonder is anyone else making them?

    Im not aware of any max total TB capacity in this desktop so I might go for 4 x 10TB drives for a total of 40TB inside?

    Thanks for any tips!

    It would appear from looking at the drive mounting holes in this link that at least 1 set of holes (nearest the connection) remains usable, this should be enough to keep the drive positioned in the mounting tray.
    A DIY zip-tie or rubber band might be used to support the back end of the drive.

    I don't know anything about the OWC SSD sled--maybe they made a universal one. But I do know that the factory Apple drive sleds for a 1,1 and 4,1 are different.

    Those are for the MacPro4,1 and MacPro5,1.....the OP needs them for the MacPro3,1.

    The solutions as noted earlier in the thread is that two of the screw holes do match up & that combined with some gaffer tape or other fixing is sufficient to hold the drive in the sled.

    ( SORRY EVERYONE - this mod is only for SSD drives . . but still perhaps useful )

    I make my own sled adaptors.
    4 Flat head screws + washers & 2 nuts. + a piece of plastic/metal with one L-shaped side.
    Lay the cMP down on it's side ( powered off of course).
    Insert the SSD drive lightly taped to the original Apple sled into the onboard SATA socket.
    Ensure that thereis a solid connection.
    Wrap new tape tightly around both the whole contrived & original sled.
    Now you can see where to drill the holes for permanent instalation on the Apple sled.
    (NOTE : You will have to champer the 'side' holes to allow the two flathead screws + washer & nut to be flush.)

    30 minute job. :)
