32bit pci ... cheaper motherboard ( say $50 - $200 range )
64bit pci ... $250 - $500 motherboards
- 64bit pci cards are also more expensive
you can obviously transfer more data on 64bit pci w/o running
into bandwidth/bottleneck problems on the pci slots
if $$$ is readily available .. buy the 3ware
if raid monitoring is an issue ... use sw raid1 instead
nobody recommends promise hw raid controllers ( doesnt "work right" )
work right is: ...
- no data loss ... no hand holding ..
- pull the disk out while you're writing a 2GB file to disks
and insert a fresh disk snd see what happens
( a good raid1 should merrily just write and mirror itself
( to the new/freshly inserted disk
- while the disk ( hda/ sda ) is out...
reboot the system and see if you can do a handsoff
( keyboardless ) boot
-----------
since you gonna spend the $200 - $400 fro the hw raid card..
- you may as well do the same benchmark tests with sw raid setup
and see if the $$$ spent is worth it
- disk speed performance
- raid1 mirroring working or not
