[rescue] 36G SCA drives still looking

The only thing that worries me about SATA drives is that the hda is 
(quoting a friend of mine that works for a HD mfr) "identical to the 
ones used in our IDE line"..
anyone notice how long ata drives last these days? I've got 10+year old 
st-506 drives on the shelf that will fire up still, a few of them after 
4+ years of 24/7 operation.
I have a bunch of SCSI drives in an array on a proliant 6000 that ran 
24/7 for 2+ years before I got them over 2 years ago, anyone know of an 
IDE drive that will?

reliability is suspect, and until I see some real world numbers (not 
MTBF #'s, I worked at DEC when we rolled out our 5 1/4" drives, I know 
how MTBF is calculated..)
