The only issue I've ever seen has been with the onboard fakeraid stuff more and more vendors seem to be adding. I've been using SATA disks with centos since the early 4.x days without issue, so you have me at a bit of a loss here. I'd say if anything it's due to controller support, and much of that can be chalked up to what hardware vendors are pawning off as 'controllers' these days.
The one problem I've seen and posted here was w.r.t. smartd error reports showing 2^32 - 1 errors on one of the disks (probably my system disk) every few minutes. I thought this was more than just a bit suspicious, since there are only 4,687,500,000 sectors on a 300GB disk, and the likelihood of having errors on 4,294,967,295 (~92%) of them is rather slim unless the whole system is crashing a lot (it's not). It's a Seagate 300GB, so I ran Seagate's SeaTools on it in lightweight mode, and no problems were reported, which is good because the disk is only about a year and a half old and has my CentOS root, swap, boot and home partitions on it.
I'll dig deeper on this one - sounds fishy to me, too, now....
