Mixing different models/series for RAID

-Does it matter or should it be all okay, with onboard raid controller, with mix match hard drives for a raid mirror?

For example, having a seagate 7200.9 and a 7200.10(perpendicular) as raid 1 when both are SATA2 with 16mb cache at 500GB and same spindle speed of 7200rpm. Yes, obviously the firmware will be different.
 
Thanksgiving dinner bump.

Another example I may want to attempt is to raid-1 a WD 250GB and a Seagate 250MB. They both have same cache and speeds.
 
Both solution will work. The 7200.10 might have a faster access time, but it will just wait after it gets its stuff for the other - shouldn't be noticeable unless the disk has to do a full revolution cause it's missed the next block while waiting. I'm betting it will be fine.

It doesn't matter if they're different speeds, different manufacturers, different caches, and usually even different sizes (the 'extra' space will either be unusable or usable as a non-raid volume). Hell, you could use drives on different interfaces if you want (with software RAID, or if you used adapters to make them all work on one hardware RAID controller).
