Hi Ish,
Not quite sure what you mean by an adaptor. Is it to do with the size of the SSD drive or the connection to the computer?
I bought a SSD drive not too long ago and it came with a metal frame to which it has to be attached before mounting it in the computer.
Other than that there was no extra adapters required, the normal sata connections plugged in to the drive just like a normal HD.
Cheers,
