Let’s see what’s in the bucket:
… and a first Gen Unibody Macbook
While the 1TB Western Digital with its 1,3cm fits perfectly well into the standard hard drive slot, it does not in the Optobay/DVD slot.
Funnily it is still possible to screw down the case (with some slight force). Nevertheless here’s why you might not want to do it.
Against the general advice I switched the drives again. Now the 1TB drive is in the Standard hard drive slot and the SSD in the Optobay.
To solve this you need to disbale automatic hibernation to disk.
pmset -a hibernatemode 0
But please be aware that now you also need to be more careful with your sleep mode as the RAM content is no more written to the hard drive when the battery is drawn. Just be aware of that and remember to no put your Macbook to sleep when there’s only a few percent of battery power left. Otherwise you increase the chance of a data loss when the battery is gets empty while in sleep mode.
With the additional SSD the Macbook actually runs shorter in battery mode. I forgot to check what this is in minutes but it is significant (~30min.).
Sometimes when booting cold the boot drive is not recognized. You need to press ALT while booting and manually select the SSD as boot drive again. Annoying.
So, while having all this painful side effect there’s one thing that still makes it worth the consideration:

I tested the perfomance of the SSD in the Optobay/DVD slot and the standard drive slot. It’s basically the same. You have to consider this when you are using a current Macbook Pro model and a SATA-III SSD as the Macbook supports the full speed/SATA-III only for the default drive slot.
