If you are extracting to "/media/sda<n>", then the problem may well be
that the "/media/*" mounts are all mounted with the "sync" flag.
mount -o remount,async /media/sda<n>
And try again - it should be orders of magnitude faster.
BTW, mounting sync is a Very Good thing normally, as it limits
filesystem corruption in the inevitable case of the FR crashing on you,
but the cost is that write operations are far far slower. Also note
that if the GPS is turned on, then SD card operations will be slower still.
