re: Comment: Will 2010 see SSD technology topping out?

Ahhh. Let's see whose memory is short and volatile. Mr. Doller is on record claiming that his 45nm (1Gbit) PCM chip would be available by mid 2009: www.eetimes.com/207001799 It is February 2010 now, and the 1Gbit PCM is not in volume production. Not at all. Can Mr. Doller explain that failure to deliver a commercial 45nm PCM product? The only "commercial" PCM chip is the 128Mbit 90nm disaster formerly known as Alverstone (now Omneo P8P?) which writes at less than 1 megabyte per second, that is, 2x slower than Numonyx's own NOR and up to 15x slower than NAND. So, no, nobody in their right mind would use PCM in SSDs, even when costs per gigabyte are ignored. Those costs, by the way, appear to be about $200 per gigabyte for the Omneo P8P, or 100x as expensive as NAND, and about $60 per gigabyte for the "upcoming" 45nm part, 30x as expensive as NAND, assuming that 45nm part ever gets delivered in volume, based on a chart from a recent Numonyx presentation. Just watch this webcast and calculate the horrible write speed yourself: event.on24.com/r.htm?e=183505&s=1&k=7BCF2A67876DA214BFF6D18937E47D44 In the mean time, Fusion-io has been delivering for months a reliable NAND-based non-volatile "SSD" that writes at 1.4 gigabytes per second and reads at 1.5 gigabytes per second. And, yes, it is perfect for the enterprise. Unlike the PCM, which has been promised since 1970s, but never arrived.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
