To warn you that is only a matter of time (there is a matter of randomness involved), I use the same setup, so make a copy with the dd option of your partition table and put it on a safe place on the sdd drive (like /root). If it fries your bootsector you can easily retrieve it then. Make also a backup regurarly of your /home (I can recoommend backintime for that -> use a folder on your sdd as the backup folder, eg /var/backintime). Once it did not only fry my bootsector but also the journal, causing serious damage to my ext4 partition, beyond the table and what fsck can do, so then I really had to reformat it. It hangs during suspend or hibernate (or closing the laptop cover) because when it comes back it recognizes your card as a new one and mounts it as a new drive, instead of recognizing it as the old one. The systems searches for the old one to open the /home, cannot find it and the system crashes. I have not been lucky in fixing this yet. I need some extra waiting time as soon as the kernel awakens, to have enough electricity running through the card, but I don't know how to implement that. Making extra pm-util hooks does not work, as they are called too late.
to backup your partition table: dd if=/dev/mmcblk0 of=/root/backupSD.img bs=512 count=1 to recover: dd of=/dev/mmcblk0 if=/root/backupSD.img bs=512 count=1 Not necessary to include that in a script or something, you can also use that when you need it...
