Is a port multiplier a decent option? I looked at the 3124 after you mentioned it and a few of the other controllers offered by Silicon Image. I had been looking at the Adaptec 2240900-R PCI Express and HighPoint RocketRAID 2300 PCI Express. These are both *raid* cards. But if they can be used as a regular controller card, they both provide 4 SATA ports and are PCI-e. But sounds like the RocketRAID doesn't work with the 2.6.22+ kernel (according to newegg reviewers). It sounds like the Adaptec works quite nicely though. > > The other possibility is the Marvell based 8 port "dumb" SATA controller > from Supermicro. > > http://www.supermicro.com/products/accessories/addon/AoC-SAT2-MV8.cfm > > It is PCI-X though, but there are plenty of boards around still with > these slots. > > My only concern here is the opening comment in the driver: > > " 1) Needs a full errata audit for all chipsets.

Sounds pretty iffy there. That Adaptec card I mentioned is going for about 100 USD. Seems like a lot for 4 ports. But sounds like it works nicely with linux, and I would only need 1 or 2 of them (plus the 6 or 8 ports on the motherboard) to be able to use all 12 drives. Do you know of any concerns of using all the ports on a motherboard?
