Maloney said Intel was very interested in the use of NAND flash in mobile devices as well as in PCs. The Santa Rosa platform, an updated version of the company's popular Centrino brand, is scheduled for release in the first quarter of 2007, according to Maloney. 2) Maloney demonstrated the advantages of flash technology in PCs, by booting up two PCs on stage, one with flash, and the other without. The PC with flash booted up in about half the time. The flash-based PC also consumed slightly less power. According to Maloney, the demonstration PC had 256 megabytes of NAND flash "under the hood." But he said it was still unclear how much flash would be incorporated into the Santa Rosa platform. 3) "The technology scales way up," said Maloney. "It just comes down to what's the cost curve on NAND." At some point, he said, there is the potential of running a PC's entire operating system from NAND instead of from the hard drive, where it currently resides. 1) It's impressive that 256MB has such an effect, but half the time isn't fast enough. I'd say "instant boot" needs to be under 3 seconds, but I'm guessing anything less than 10 seconds will be called that by the marketing folks. The cost of 256MB today is negligible. Would you pay an extra $10 for your laptop to have the instant boot feature? By 2007/8, the minimum you'll be looking at is 1GB. A good rule of thumb might be a 1:1 DRAM:FLASH as a low end, and I expect 1GB to be the common DRAM size by then. A better ratio will be 1:2 or 1:4 to give room for quick sleep/hibernate/wakeup modes and applications quick starts. An extra $20-50 is not a big deal on a $1000+ laptop, but we'll probably not see it on the low end. 2) The "slightly less power" will be interesting to see if it scales as well if there was a significantly larger amount of flash for those users that want to stretch out the battery life. An extra 30 minutes or 1 hour would be significant and potentially achievable if the hard drive can be spun down a good percentage of the time. If I'm on a flight editing a Word or Excel document and it's all residing on flash, I don't have to touch the hard drive. 3) "The technology scales way up" - is there a limit? As long as costs keep coming down faster than HD, someday, the limit will be the same as HD for some people; get the biggest you can afford or the biggest they build. Not mentioned was the speed improvement of flash over hard drive. The overall system performance of a slightly slower CPU with flash versus faster CPU without flash may be comparable, especially in applications with lots of HD reads. People pay hundreds more for a little improvement in CPU performance that doesn't really add that much to overall system performance. This could prove to be a better overall value as far as system improvement.
