Im thinking of going with the PROMISE FASTTRAK S150 SX4 for a Raid 5 Setup. Its on a 32bit bus, and I need the storage space so the Raid 5 isn't for speed or anything just reduundancy.

What im wondering is... Since this card is about $240 CAD its most likely not a true hardware card.. WOuld it be the same as running a linux raid array (what i was going to do originally)

Figure why bother if there going to be similar in performance/stability.

Thanks for any info.

RAID 5 controller's traditionally require a dedicated CPU to perform the XOR calculations and manage the array. Instead of adding a costly CPU to the controller. Promise"s FastTral S150 SX4
controller uses an inegrated XOR engine for parity calculations, delivering extraordinary performance at a dramatically lower price.

what exactly that means....

my SX6000 has that dedicated RISC processor
I think its safe to say its at least partly hardware assisted
and the total cost of course increases with the SDRAM cache it requires (up to 256MB)

you did note that its a 32bit 66MHz card
(backward compatible to 32bit 33MHz Id assume)
