different drives in raid 5

I have a raid configuration in one of my file servers consisiting of a perc 5i with 256 megs of cache the arrary is made up of 5 Samsung 2TB drives 5400RPM and 32 megs of cache. I just got 3 Western digital red series drives they are 2TB 5400RPM but they have 64 megs of cache. So my question is will it be a problem adding the WD's into the raid 5 array since they have different cache sizes I always thought the most important was having the same drive size and speed?

On any Raid Array that I've ever built I've been cautious of not only the same model drive #, I go as far as to verify the same FIRMWARE on the drive!

I would not do what you are suggesting.... It's asking for trouble.

Is this server a Dell brand?
Will you be using the new drives on a separate buss?
