AMD’s 890GX delivers a staggering 180MB/s in random write performance, a full 31% faster than Intel’s X58. The random write speed makes me believe that with a bit of driver and/or BIOS work we can get random read performance up there as well.

"We have to give AMD credit here. Its platform group has clearly done the right thing. By switching to PCIe 2.0 completely and enabling 6Gbps SATA today, its platforms won’t be a bottleneck for any early adopters of fast SSDs. For Intel these issues don't go away until 2011 with the 6-series chipsets (Cougar Point) which will at least enable 6Gbps SATA."
I would recommend reading the whole article starting from page 1. It seems many mobo manufacturers are using workarounds to the default 1 lane of PCI bandwidth to the Intel SATA controllers on the non X58 mobos. But what is going into the Dell econoboxes?
I'm also curious what caused his Crucial C300 died of. And what two of them in RAID 0 do in terms of showing up controller limitations.
*idle rambling* Clearly these limits aren't going to be hit in most use cases today. Joe Average checking his gmail and browsing the web is not going to be impacted. However, who could have imagined an SSD under a $1000 delivering over 300MB/sec and 20,000 IOPS even 3 years ago.
In three years time, that kind of performance could be stock standard. And that's when the limits will be hit. *end rambling*
