ASUS delivers feasible SATA 6Gb/s solution on this new high-end P55 motherboard.
This new motherboard from ASUS has one thing going for it and that is the "proper" - or better - implementation of a SATA 6Gb/s chip for the bandwidth hungry SSDs of this world.
Below, what ASUS calls "Other Storage Solutions", friendly words for bad storage solutions.
ASRock is one manufacturer providing a SATA 6Gb/s add-on card with their top P55 board and is also using the Marvell 9123 chipset.
The PCI-e 2.0 x1 interface provides 500MB/s, still 100MB/s shy.
This can be good or bad, depending on how you look at it. While you can't deliver more than 500MB/s to the CPU/RAM, you can move data between two HDDs/SSDs at the full 600MB/s. The bottleneck is just between the controller and the P55 PCH, other than that everything will be fine. If you're hoping to get that much data to the CPU, you have to settle at 500MB/s and even using RAID on SATA 6Gb SSDs will yield you no more than that.
Same goes for ASRock, the controller can move data at 600MB/s between drives connected to it, it just can go further than 250MB/s to the CPU.
344MB/s in burst speed and not much more than that. It's still 100MB more than current SATA 3GB/s ports but not the improvement that everyone was expecting. A few more months, one upcoming AMD SB800 southbridge and faster SSDs and that will be radically different.
The pricing of the P7P55D Premium is expected to be close to $250.
