SATAII RAID 5

Depends very highly on what performance increases you are looking for that you think a RAID setup would provide.
 
Higher transfer rate and lower cpu load than onboard, Data redundancy is important for the amount of disc space i'll have, 1TB

The board i'll be getting only does RAID 5 on SATA1 too
 
Onboard RAID5 is a bit of a nightmare, without a hardware XOR engine the write speeds will be poor - around 15Mb/s in most reviews, that's USB2 external speed!

The RocketRaid cards are nice, I use the 8 port version myself, good value for money with enough hardware support for a decent write speed (45Mb/s or so), cracking read speed (I average about 150Mb/s) but maybe lacking some of the toys of an Areca or Broadcomm card. That said they're a third of the price of the fancy cards.

Take a look at this thread for my other comments on the RocketRaid cards.
 
RocketRAID's don't have onboard XOR processors so aren't actually true hardware raid - they are just an accelerated software RAID. I wouldn't spend money on that. I would save up a bit more and get a proper card.

Hmm, now there are some available, but I think I will be berated once people see the prices. :D.

Auction sites are pretty good for this sort of thing.

The card I'm saving for is the 8 port Areca 1220. Ouch when you see the price :D.

There are many cheaper alternatives though - lemme have a quick gander :).
 
Promise SuperTrak EX4350 - comes in at 240 hit points though :D.

Of course, I'd recommend the 8 port version for 'only' 30-40 hit points more.

Personally, I'd live with the 20Mb/s software RAID5 rather than forking out 100 odd for something which is only slightly better (and only in writes - reads are the same). How often do you write to an HDU? Ok - installing, graphics work/editing
