just picked up a new perc 6/i off ebay and need to start purchasing drives for it
I do have some of the samsung HD204UI's and they seem to support CCTL quite easily
setting this using the command line from behind the perc is probably a different story.
I was a bit worried with regards to this whole CCTL/TLER business
and since I am buying these drives new
what do people recommend?
It'll probably be a raid 5 4x 2TB array.
Personally I use 8 RE3s on my PERC, but that is because I got them really cheap (GBP50 for all 10 of them). I probably wouldn't run a PERC with any consumer grade drives myself though (would go *nix software RAID over iSCSI instead) but that's because I'm paranoid.
CCTL is easy to set up through a *nix commandline, but less easy through Windows and I don't believe you can set it at all through the PERC. Also remember that it is a volatile setting, and returns to default on a power cycle.

In RAID5, if a single drive drops out, the array goes degraded. You can remove and re-add the drive, have it rebuild and wait for it to happen again.
If a second drive drops out before the rebuild has completed, the array fails and it's pot luck as to what you can salvage - depending on what you do to the array you may recover everything, alternatively everything may be lost.
In RAID6 you get a buffer of an extra drive, but rebuilds also take longer.
