Okay, that sounds workable. 20 MB/s read listed there too. Man, that's gonna be slow to load off!
Flash speeds
are increasing. With two chips it increases to 40MB/S, 4 is 80MB/S and if flash scales to say 150% of the original speed in the intervening time of 2-3 years it becomes 30, 60 and 120MB/S respectively.
You think another $25 on top of the $25 for the HDD itself? Sounds high to me. I'm in agreement with corduroygt, that you'll have the interface anyway because these companies want owners to upgrade to HDD and buy DLC. So as I see it, it really is a choice of ~$25 on an HDD, or ~$25 on flash.
I was thinking about $30-$35 for the drive itself because the first model defines the system as far as expected read speed so they would want a higher density platter with as high a read speed as possible for the first model which rotates at 7200RPM. If they rely on this component for loading then it makes sense that it deliver at least 130MB/S average read throughput. Then you can add a few dollars here and there for ancilliary sata controllers, power, packaging, shipping and retail margins.
Only because Wii is sans HDD! Next gen if they get the chance to sell DLC, they'll take it. And if they go with reasonable specs and 16+GB titles on a 2GBs of RAM system, they're going to need one to overcome huge loading delays. Technically and economically I can't see any way to pair 2+GB of RAM to a non-HDD system. Will holographic drives offer a plausible solution?
I don't actually see Nintendo moving past 1GB of ram for their next system, they would likely target at maximum 4 32/16bit 2Gbit DRAM modules and a HDD is out because they have obvious packaging requirements, so flash is still in as far as I can see for Nintendo.
Nintendo would still want their console to be small and ubotrusive because they'd believe it served them well this time around. So again they will probably not be able to package a 2.5" HDD nor bulky cooling within their desired form factor.
Overall theres no harm in using flash to keep the overall entry level cost of a system down. So long as the people who abhor loading like yourself are satisfied then it doesn't matter if a lower end system which you'd never buy comes with say 16GB of flash (8 user, 8 cache) if that satisfies a part of the market that doesn't care too much.
