I have used an Acard AEC-7720U combined with a 2.5" 8GB Transcend SSD IDE drive with 2.5" to 3.5" convertor.
Even though Acard says the AEC-7720U does not support hard drives, I have got zero problems with the setup.
I don't know if it works with other SSD or IDE hard drives.
The Acard adapters I got were reasonably cheap, around 100$, but I bought them many years ago too, now they are rare.
