Not necessarily bad to go with Dell. There are *some* of their
controllers that are wicked fast in some configurations. However,
finding which ones are fast is very tricky unless you buy + return
the box you want to test :-)

FUD!!!
They don't randomly change the controllers under the same name. If
you order a PERC4e/Si controller you will get the same controller
every time. This particular controller (found in their PE1850) is
incredibly fast, sustaining over 80Mb/sec writes to a mirror. I
measured that during a DB mirror using slony.
