Well, that certainly isn't my experience. Did you second-hand buy all those SCSI disks by any chance? The thing is, while mechanically speaking the drives may indeed suffer from the same sort of failures (bearings wearing out, to name something), SCSI and FC are often in the 10K and 15K+ RPM range, thus are better suited for RAID/LVM protection via mirroring and striping (being a lot faster).
I have a lot of second hand scsi disks and a lot of second hand sata disks. I rarely buy anything new.

Aside reliability, about which opinions seem very mixed, the whole (P/S)ATA versus SCSI/FC discussion: You can't deny that SCSI and particularly FC outrun SATA easily. I haven't even mentioned iSCSI or SAS, the latter being an awkward hybrid of SCSI and SATA (in some regards) which appears to be making significant inroads...
imo, scsi for speed, sata for capacity and longevity.
Maybe because a 15k disk is double the speed of a 7.2 disk we can expect them to last half as long? That's certainly been my experience, anyways. YMMV.
