Can you use SD card as start up disk?

[mouztrpd]

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 know it's possible on Windows...never tried it on my Mac.

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?

How fast can you write to an SDXC?

How fast can you write to an SDXC?

I think 12X is the fastest right now.

How fast can you write to an SDXC?

up to 104 Megabytes per second

up to 104 Megabytes per second

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.
