Hmmm sort of agree, in the other one its asked if mobo or controller is the way to go... what config etc... whereas this one is a continuation and asking for what controller i should get... could have been consolidated i spose.
Let us know how it goes when you get it all together. Dont hesitate to ask some more questions if you get stuck Good Luck
Why should you want to use a PCIe 16* (if they do exist)
when looking at the typical max transfer rate of PCIe 16*
PCI Express 16x 4000 * MB/s
In theory (not looking at overhead) you shoudl be able to saturate
~4000/50 MB = 80 spindels. I dont how many spindels you want to use but on average PCIe 4* is used for internal and PCIe 8* is used for external cascaded JBODs. Im using currently a smartarray P400 (PCIe 8*) in my workstation.
Using 4 spindels.Gives me a very good performance. I wouldnt notice a difference if the P400 was equiped with a PCIe 4* bus.
It shouldnt be the bus speeds to look for but more functionality.
Both PCIe4* and PCIe 8* are fast enough for usage in a PC/ workstation.
