Hi,
I heard somewhere that on board SATA ports have shared bandwitch, meaning if I fill all of them they speed is reduced.
Im in tad of a situation, I need to connect 8 Samsung 850 PRO SSDs which have 520 even 530MB's sequential write speed. [x4 512GB a d x4 1Tb, ill do windows RAID0 for each]
I have 4 on board SATA ports [plus 2 assmedia but they dont count]
And I have a nice PCIe Gen 3.0 x8 2-Port HBA card that supports 8 SATA drives, BUT the only free PCIe slot I have is Gen 3.0 x4 so thats 4GB/s of total bandwidth [x8 x 520MB/s = 4160MB/s]
Kinda logical to connect 4 to mobo and 4 to card, but if its true that on board sata has shared bandwitch like say connected to PCIe x1, then maybe having all of them connected to the card and just losing 160MB/s total is not bad
