yo! this may be one of the dumbest questions i've ever asked but ow well, will this work on naslite-2 =http://www.amazon.co.uk/Winter-SATA-Controller-Promise-PDC20376/dp/B002T8NXSW/ref=sr_1_1?s=computers&ie=UTF8&qid=1290731012&sr=1-1
i did have a via vt6421a but i think everyone knows the problems with them
Looking at the limited detail and the pictures of the card this looks like a software Raid card (ie the Raid function is performed by the software drivers and not by a XOR Cpu on the card) that you would be very very lucky if this works in NL as a raid controller although it should work as a disk controller (I had similiar experience with a SiL 3114 based card)
If you want true Raid then you will be lookint at LSI, 3WARE, Adaptec and the like at considerably more money than that Promise based card.
Hope this helps you out a little.
