Micron is developing a PCIe-connected solid state storage card four times faster than Intel's X25-E. This is the first competitor to Fusion-io's PCI-e-connected ioDrive. In a demonstration viewable on YouTube, Joe Jeddeloh, the director of Micron's Advanced Storage Technology centre, shows Iometer testing of a dual quadcore …
It's disappointing but this seems like a bit of marketing fluff from Micron. We were at WinHEC this year and Micron demoed this product in a private session and when they were cornered about the IOPS performance based on their 400MB/s bandwidth limit per card they admitted it was in truth two cards in a sort of RAID to get this type of demo performance but they assured everyone that they planned on getting to this level of performance in the next year or two. It's exciting but it's just marketing hype.
So how many 8K IO/s does it do?
What I've found with all flash devices is that the IOPs halve as you double the transfer size.
200K at 2K, says 50K as 8K etc...
This is a fairly fundamental aspect of all flash devices. Which is why they only can do about 5 or 6x a traditional HDD in MB/s.
The ultimate question is mixed performance however, everyone can do amazing read only performance, but what happens when the workload is a much more typical 70/30 or 50/50 mix of reads and writes... that separates the men from the boys...
As for the question of RAID'ing Fusion, sure they appear to a system as a block device, so you can run software RAID in a core on the OS and get as much performance as your core can give you...
Anyone notice this MICRON blurb from a Fusion-io press release back in September, 2007?
Ian Blasch of Micron Ventures comments: “Research indicates that data is growing exponentially faster than the performance and availability of traditional storage infrastructures. We believe Fusion-io's innovative technology will address the growing demand for faster data access, while maintaining both reliability and accessibility of data. We believe this truly innovative architecture will fully leverage the inherent capabilities of NAND flash in a whole new way for enterprise customers.”
Maybe they had a falling out since Micron wasn't listed in Fusion-io's first round of VC financing in early 2008. Now Micron is trying to build their own drive to compete with Fusion-io?

By the way, isn't that Joe the Plumber in the video??? LOL
