Okay - we have several great / cheap sources for PCIe x1 2 port controller cards.

Does anyone have a source for cheap 2 (or 4) port PCI cards that are compatible with unRAID.  I need 2 more ports.

For PCI it's hard to get much cheaper than monoprice.  I know that 4 port card works. 

The SIL3114 is used on lots of inexpensive 4 port PCI cards - plenty on Ebay as well for European users who can't access Newegg/Monoprice, etc.  Just search on Ebay for "SIL3114"

These guys do the SIL3114 PCI cards for a good price (UK): http://linitx.com/viewproduct.php?prodid=11624

I've bought a couple from them.

About those 2-port JMB362 Cards - there have been 3 instances of these boards resulting in no POST lately. In at least two of the instances this has involved motherboards that already have a JMB 36x chip onboard. See this thread for details:

http://lime-technology.com/forum/index.php?topic=10165.60

Hopefully more people will write back about the cards in the above threads and hopefully there will be a pattern as to which motherboards work with these and which ones don't. In the mean time, I feel a caution and link to the above thread would be in order.

Only a few more weeks until my eBay SATA 2-port controller arrives on a tugboat from Hong Kong :D

Agreed. If it's not due to another onboard controller then it appears some newer LGA1366 boards are having issues with them. But then you are having issues on an older P35 chipset board too. So far, no reports of AMD systems having trouble with it.

Looks to be the same as this card on Newegg.

These were tried previously and wouldnt work with unRaid. SIL3124 chipset is fine but unRaid wasnt able to recognize the PCIE bridge used on these cards.

yea, that monoprice card works great for me, but a small FYI to those considering it -- it's SATA 1.0 -- a little slow.  I've got to jiggle around my drives so my smaller ones are on that card, so that a pairity check, etc gets done faster once it's past the 4 SATA 1.0 connections and moves over to just my SATA II's on the MoBo (six) -- the recommendation received was move my small drives to the SATA 1 connections, and the big drives to SATA II.

And it may be the case that being an old-fashioned PCI card that SATA 1.0 is just fine...   but if anyone has a lead on a similar, cheap 4-port PCI card that is SATA II ... drop a line here ;)

Perhaps another tweak?  SATA I, II, or III ports?

As I understand it, today's HDDs don't even saturate SATA I, so SATA II or III is basically just marketing hype.  For an SSD application it certainly matters, but it shouldn't matter for a HDD application like unRAID.

So far, I can see a difference between SATA I and II in performance...   I'm not quite OCD to graph it out though.    Especially if I'm doing port multiplying.... {of course}.   And my ancient SSD (ancient by modern standards) is an OCZ Agility which doesn't benefit from SATA III,  but certainly does for SATA II vs. SATA I.

But even internally, one-to-one, I've learned to move my "smaller" drives to the SATA I connections so that parity checks get done with the SATA I connections as soon as they can.

Although our current disks don't saturate the theoretical SATA I speed, it is plausible that the communication speed could be lower on SATA II for two reasons: a) practical speed on SATA I may be lower than the theoretical, and b) the faster link will have lower latency. That being said, I would expect the difference to be fairly minor - small enouth to probably not need to worry about. But I do like raw data to prove me wrong  ;)

I have a question about these SATA expansion / controller cards with regard to PCI-e slots and bandwidth. I notice that typically products will follow the below trend:

PCI-e x1 slot = 2 port expansion cards available
PCI-e x4 slot = 4 port expansion cards available (and some 8 port)
PCI-e x8 slot = 8 port + expansion cards available

I understand that this is to do with bandwidth of each slot and not producing products that would be bottlenecked by each slot. However, the above does not make sense to me…

Why do we not have for example 4 port cards available for PCI-e x1 slots? PCI-e version 2.0 x1 slots, have a maximum bandwidth of 500 MB/s. Taking the assumption that each drive attached to this slot could be reading/writing at a theoretical 125MB/s each (max possible over gigabit ethernet) then we have:

500 / 125 = 4 possible drives

So we could have 4 hard disk drives attached to a PCI-e 2.0 x1 slot if they manufactured a card that had 4 ports. Yet we only see cards with 2 ports on x1 slots.

I can understand this scenario if you take into account the cards are only manufactured for PCI-e version 1.0/1.1, as then the bandwidth is halved to 250MB/s, so the above example would check out and you could have exactly 2 HDDs attached before theoretically hitting a bottleneck. Is this all it is? That nobody has bothered making a PCI-e version 2.0 x1, 4 port card? Can I assume that the reason is due to lack of demand when people can use the already out there products for x4 slots?

Reason I am interested, is that my motherboard has 2 separate x1 slots (PCI-e version 2.0) and I am trying to plan for the future what the maximum amount of hard disk drives I could handle is. I have on my motherboard:
8 x SATA ports
1 x 16x pci-e slot (version 2.0)
2 x 1x pci-e slot (version 2.0)

I think I can have 8 + 8 + 2 + 2 = 20 which nicely maximises the current licence for Pro I believe.

Wish I had that mobo with 8 SATA ports--would be all I'd need for the Plus license + top dock for pre-clear.  What is it?

I still haven't received my eBay SATA card from Hong Kong.  Ordered April 21st.

Some of the wider controller cards will work in a narrower slot if the user physically removes (e.g. melts the back with a soldering iron) the plastic at the back of the slot to allow physical insertion of the card. I am pretty sure that the BR10i, is advertised to work in a x1, x4, or x8 slot.
