Guys, some confusion is starting.
Samsung threw a new generation of drives on the market. These drives are named like this:
The older units had a naming convention like that:
SH-S223x (more detailled explained in the FAQ)
A 223F (more precisely: SH-S223F) is therefore some older stuff, and IIRC there should be some user opinions about this drive.
For the new drives, there is not much user input yet.
P.S.: @Alan: SH-S2x3* always meant Sata
