Would there be any significant performance/reliability increase if MRAM did trickle down to consumer products? If not, I'd rather have more economical SSDs based on tech that's already mature.

MRAM can be about as fast as SRAM if implemented properly (it's even being looked into as a replacement for SRAM in CPU cache because of it's high performance), even faster than DRAM, so yes, there is a definite advantage to having it beyond the fact that MRAM is one of the most reliable storage technologies ever.

Advancements are necessary at all times, even if industry begins settling on a de facto standard.

Awesome, so let's bring it on to the enthusiasts so that the average joe (spelled "me") can afford it one day.
 
[citation][nom]shin0bi272[/nom]Id still rather have PCM chips but this is cool too.[/citation]

MRAM is more reliable and faster than PCM, although PCM seems cheaper at this time. It's all trade-offs.

(MRAM could actually be made cheap, but it has certain problems. There are multiple methods used to alleviate them, but they are never all used in one device because the different methods are all owned by different people. If they got together, it could be made a lot cheaper and even faster without sacrificing reliability. Greed is kinda stupid in how it will avoid greater avenues for making money if other people who you aren't on great terms with also profit from a venture.

Why did people vote your earlier comment down? I thought that it was a legitimate question.

Ahhh, given my Apple-neutral/objectivist stance I'm used to it...I didn't even notice.

When technological "advancements" turn out to not be a good deal better than former tech, then improvements on the former, more mature technology can outpace the newer "advancing" technology. For example, hard drives are among the oldest technologies still in almost universal use in modern computers and despite their age and disadvantages against newer technology, they are still far more suitable for many situations. In fact, if you want a high speed hard drive, then they can be made. A 15KRPM drive with four read/write heads would surprise you (no modern drives have more than one read/write head anymore, but it could be done) in just how fast it could be for both sequential and even random throughput. Just because something is newer, doesn't' make it better. That is what Halcyon's question was about, whether or not MRAM was actually an improvement over the older technologies, at least that's what I thought the question was about.

This was a good comment with a ton of reasonable responses it makes no sense people voted it down. Anyways...

MRAM won't make it to consumers unless they end up with extra chips they need to clear. Most of the time when high speed cache is needed, they use DRAM. The system can be designed to overcome power loss-based data loss by either integrating a capacitor (old school method) or by carefully balancing the components so there is enough inert charge in the system to write out the cache before losing its remaining charge (they actually do this in devices like I think the samsung 830).

"It's not entirely unreasonable to foresee an MRAM SSD for the consumer market at some point in the future."

It is entirely unreasonable unfortunately. The reason cost is so high is because feature size is so high. This in turn means it cannot run as fast as conventional DRAM, RERAM, etc. (because of heat/power concerns, etc)

RERAM (also) is sorta the death knell of any hope of old-school memristor tech, and recently prototype reram chips have hit the news...

I don't care if its a someRAM or a tortilla chip, really, I just want ultra ultra fast storage in useful capacities at a price I can afford to pay. I don't want to wait on my computers...I want them to wait on me.
