That is absolutely correct.
However....
Finding a IDE/PATA drive that actually fits
onto that adapter is an entirely different matter.
Most of the more recent additions to PS2Drives are SATA drives and since the list has no way to distinguish SATA from PATA, it's now completely useless as a reference. So far, the PATA drives I'm finding are running roughly $100 or more a pop new. About 2-3 times the amount for the equivalent sized SATA drive.
The whole SATA thing was puzzling me though. Even found one moron who was adamant he had a SATA in his PS2 but couldn't produce proof. So wielding some SearchFU in my partially blinded state (don't ask), I discovered the following.
A Chinese company has created a SATA adapater for the PS2.

ethernet warning sticker is a necessary part of its constructions which makes it somewhat less attractive. Of course, there really isn't a whole lot of online activity on the PS2 scene now so it might be a wash. Still, I hate ugly things like that. I would like the flexibility of leveraging the NIC in some fashion.
So, my options are:
1) Pay through the nose for discontinued hardware.
2) Figure out how to stuff a 2.5" SATA drive and SATA->PATA adapter inside that space (I see talk, but no concrete proof it's been done).
3) Get an external, matching enclosure.
4) Get that Chinese SATA minus NIC adapter.
