Katero PCI-E SATA 6 + USB 3 kartico kupiti?

There are two versions of the card, the current version uses the ubiquitous Marvell 88SE9120 SATA Rev3.0 controller, the Renesas/NEC ?PD720200 USB 3.0 controller, both connected through a PLX PEX8608 PCIe bridge. Although the card uses a 4x lane PCIe 2.0 interface to the PLX bridge, both of the controllers are connected to the bridge by only a 1x lane interface. These single lane controllers are significant bottlenecks on the speed of both the SATA and USB ports, especially when used for connecting SATA III SSD's. The SATA bottleneck would not be a problem for HDD's. In practice, the USB bottleneck will probably not be very noticeable due to protocol overheads

[snip]PCIe x1 5.0Gbps. x1 why x1, its a x4 card running in a x8 slot?

After some digging I found this spec document on the controller, Marvell 88SE91xx Product Brief. If you read this the spec fo the controller shows this..

The controller only supports a single x1 connection.

I feel a bit duped. I specifically got this card for its x4 connection, but given the fact the marvel controller only accepts a x1 connection the SATA will only ever be able to run at this speed. I have read other people suggest that the x4 is used to split the channel in half and use some of the x 4 bandwidth for the USB 3.0 controller, which would make sense but it seems like false advertising to me.

Meni se vseeno zdi "false advertising" -- vse kar ma ta kartica od x4 je slot, ki ga zahteva.
