How long have you had them in production?
Were you able to adjust the TLER settings from within solaris?
Thanks,
Tristan.

We've been using caviar black 1TB with disk configurations consisting 64
disks or more. They are working just fine.

Yes, I'm aware of the issue, and am using 16x RE4 drives in my current
box right now (which I unfortunately had to convert to CentOS 5.3 for
Oracle/
custom software compatibility reasons). I've made very bad experiences
with Seagate 7200.11 in RAID in the past.
Thanks for your advice against Caviar Black.

Yes, dual-socket quadcore Xeon.
