SD card reader firewire - does it exist?

Last week I bought the fast 95Mb/sec SD card for my A77, but after a good series of testshots my shoes fell off when I saw the estimated time for upload to the computer: 3 hours,- and the card wasn't even half full....

My Mac doesn't have USB-3. With CF for the A700 until now I was using the firewire port instead, with the excellent firewire CF cardreader from SanDisk.

Does such a reader actually exist for the SD- family of cards?

Or how do other A65~77 users here manage a good and fast file transfer (other than USB.3)?

Thanks in advance!
