I understand what you're saying but the equipment they used to design the old ram *doesn't go away*, it doesn't just magically disappear, we're talking about IC's here, we're not talking about tool and or car manufacturing. I really REALLY doubt it would be expensive to take a look at older SDRAM, and turn it into a product (i.e. not an i-ram where people have go out and buy 'sticks' of it to put it into their IRAM). Have an actual small drive, ala something like Western Digital did with the Raptor (34GB/74GB 10,000 rpm) have it as an add-in card (like they did for 3D video cards, notice the amount of integrated RAM on modern video cards) or SATA device by itself, , or have it on SATA, IMO they could probably use older ram designs on modern SATA/PCI/PCI-E, and have a much better product then i-ram for a lot cheaper with no heat issues, trace issues, timing, etc, because the technology has been 1) Perfected and 2) ridiculously cheap because all the R&D has already been done, all it would require is 1) Sticking ram chips onto an PCB + controller. 2) Battery backup. This is not rocket science here.
1. Regular desktop users do not want or need a RAMdisk. A HDD with very large (128MB+), and 'smart' caches to hide latency and bandwidth for small amounts of data would be cool (a few companies are working on those, IIRC), but a RAMdisk is very much a low-volume, enthusiast and workstation only thing. There is no way, with such a small demand, to make the product both cheap and worthwhile to build.
2. The R&D has been done for DDR and DDR-II, as far as the RAM itself is concerned.
Gigabyte has to stick a controller that will convert it to a standard drive, as far as the SATA controller knows, and a SATA controller (straight PCI-E alone would could offer bettwer bandwidth now or pretty soon, depending on chipset), then make a BIOS for them. Using older RAM might make for a slightly simpler PCB, but otherwise, it wouldn't be any easier. They'd have to do as much R&D for SDRAM as DDR or DDR-II.
3. The old technology might not go away, but it also does not get cheaper. Right now, DDR-II 400 would be the most cost-effective RAM to buy. Why worry about SDRAM? It's more expensive.
4. As with #1, a product like the I-RAM does not, and will not, have enough of a demand to warrant special memory upgrade modules. It ceases to be cost-effective at that point.
Technically, what you're taling about would be pretty cool. But who will buy it? As it is, very few people are going to buy a product like the I-RAM, and it, as it currently exists, is a simple and awesome way to implement a RAMdisk.
Er, uh, sorry for the hijack. I actually did come in with a question
