July 15, 201015 yr Hello I need at least 2 more internal SATA connectors What will be the difference between a PCI-Express card and a PCI card? How it will affect the transfer rate (in %) Thanks
July 15, 201015 yr Typical PCI slot (33mhz, 32bit) has a maximum bandwidth of 133 MB/s shared across ALL PCI Devices. If you add 2 drives, that limits the maximum possible parity checks, parity rebuilds, simultaneous reads or writes to under 66 MB/s. With 4 drives on PCI the limit is below 33 MB/s. A typical single lane PCI-Express 1.0 has a maximum bandwidth of 250 MB/s, a typical 4-lane PCI-Express is 1000 MB/s, and a typical 8-lane PCI-Express is 2000 MB/s, with 16-lane PCI-Express bandwidth of 4000 MB/s. This is per slot. If you have 2 Single-Lane PCI-Express slots, each one has dedicated 250 MB/s, for combined effective bandwidth of 500 MB/s. PCI-Express 2.0 slots provide twice the bandwidth as well, so a 16-lane PCI-Express 2.0 slot provides for 8000 MB/s. As you can see, PCI-Express provides significantly more bandwidth than the typical PCI Slot used (33mhz, 32bit).
July 15, 201015 yr What woul be the cheapest PCI-e card with 2 connectors? http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10407&cs_id=1040702&p_id=2530&seq=1&format=2
July 15, 201015 yr The one from Monoprice won't be the cheapest if the "french_guy" lives in France. That's why the location is kind of important when someone asks about the "cheapest"...... He should be able to find similar cards in any local computer store or if he is computer savvy he may venture to dealextreme where he can get a similar one for US$13-14 (shipping included) - whuch may or may not work well with Unraid.

July 15, 201015 yr Author Actually I'm French but I live in the US (detroit area) Does the board at Monoprice work with Unraid?
