I'd want to take a closer look at the general health of the drives 
themselves (grown defect list, ECC correction count, uncorrectable error 
count and the like) using a tool like smartctl - recent smartmontools 
releases have support for looking at drives behind perc 4s - search for 
megaraid in:

http://smartmontools.sourceforge.net/man/smartctl.8.html

alternatively if getting smartctl onto this box is fiddly (and you can 
easily take the drives offline) it might be easier to plug the drives 
into a plain SCSI controller on a more modern box...

HTH,

Tim.
