I would like to add some SATA ports to older servers (2 x PCIe x4, 1 x PCIe x 8) and I need to be able to use the max. speed of the HDDs attached to them - in parallel/all at the same time.
The HDDs are capable of delivering ~ 220MB/s read/write speed.
What I do find, are PCIe x1 cards like
InLine 76617G, 8x SATA 6Gb/s, PCIe 2.0 x1
but these obviously max out at some 750 MB/s interface speed. Probably under normal load conditions that would be fine to serve 3 HDDs at a time, however, as mentioned, I'd need at least 1.6GB/s bandwidth.
There are some older PCIex8 RAID controllers like the Areca 1220, but these unfortunately deliver only a 400MB/s bandwidth (actually trying to replace these) even when used in non-RAID mode with just "pass through" disks.
I also have been able to find a 8-port PCIe x2 card from Syba, which comes closest. Or alternately I could use two 4-port PCIe x2 cards as offered on Amazon. With the backdraw of losing 1 PCIe x 4 port.
So back to the title of this question: Is there a 8port SATA 6g PCIe x4 non-raid card - preferably below $80.
