S.M.A.R.T. is supposed to be an industry standard. Now, disk manufacturers 
can on one hand implement only a part of the parameters or introduce 
extensions to this standard; some other times they might have their own 
interpretation of what a parameter should mean. My impression is that it 
doesn't depend on whether they are cheap drives or not, but more on the 
manufacturer - f.e. I got almost the same parameters for IBM drives from 
different drive families of various ages (last 2 years or so).

IDE controllers cards or mainboards have had S.M.A.R.T. related functions 
for several years - I have Intel 440BX based mainboards from 1998 that 
offer the option of enabling it and give a warning message if something is 
wrong with the disk at boot time.
