    Instead of paying for the solid state drive in the new iMac is possible to use a SD card as the start up disk?

    I don't know, but SD cards don't use the same technology as SSDs, and it will be abysmally slow, unless you can find an SD card with read and write speeds above 30MB/s, as most are only around 5-10MB/s.

    Internal S-ATA HDDs have read and write speeds of around 75MB/s and more.

    What for, so that it is slower than a hard disk?

    I think 12X is the fastest right now.

    Current cards write up to 35 MB/s.

    Even with the faster SDXC cards coming, they will be much slower than using a hard drive. You are better off using the SD for storage.
