We had a chat with the Kingston labs team this week in California and noted down some free performance improvements, and limitations, you should be aware of if you own one or more SSDs:
- The Intel SATA ICH9R/10R/P55 controller under RAID-0 has a maximum real world performance capacity of about 600MB/s in total between it and the CPU.
Despite the fact you'll need several (four+) SSDs to hit this limit at the moment, it's worth bearing in mind that to get ludicrous performance you'll need at least a PCI-Express x8 card.
Until Intel increases its DMI and/or SATA controller bandwidth, this could prove a more regular limiting issue when future SATA 6Gbps parts arrive.

What else can motherboard manufacturers do to increase the features and sell us new things?
We've got plenty of everything these days: SATA, USB, Gigabit Ethernet, HD sound - it's all "good enough". Motherboard manufacturers are stretching to include energy efficiency wherever they can, and more recently, extreme overclocking and cool designs to draw people into upgrading but for the most part the core hardware levels have remained the same for several years. We're still looking at six to eight USB on the rear I/O, six SATA (sometimes more) on the board and a couple of Gigabit Ethernet sockets.
What have northbridges become? Nothing much - what more can you do with PCI-Express? We've hit two/three/four lanes of x16 or x8 at a squillion MT/s and it's now all pretty normal.
