I don't have time to make regular backups, so it's just not an option for me.

all SATA drives and all ATA100 drives have had Sector remapping as a standard feature. it was right around the time that ATA66 was rolling around that the feature started to be implemented on IDE drives.
I have a 4 disc ATA100 array with 40GB WD drices on it, I have thrashed that drive ( its a 160GB array thats in a windows soft RAID0 with 2 120GB drices( with the leftover 40GB going to another partition) its an array I have 90% full of broadcast quality video for editing, so needless to say the array gets beat to crap doing that stuff.
never as little as a hickup with the PROMISE controler it rides on.
and "frequent" backups are not that hard or time consuming. I think it takes about 8 hours for me to get my entire network backed up on DLT's. with a total time of me having to pay attention to it of about 15 minutes. ( to swap tapes).
Also going with single discs is not a safe guard anyway. hell out of every 20 or so SCSI discs that come into me at work, one dies in a few weeks. And these are top end Seagate or Fujitsu 15kRPM U320 73GB SCSI drives.
I dont count on any ATA to last long at all. if you want protection, backup, if you dont, then I dont think your really at any greater risk with one drive or 2.
