Well, I have always wondered why Headware and other computer memories were so bloody expensive compared to the very, VERY cheap OMC chips, well I got a reasonable explanation from Fanpro about it.

Headware and computer memory is active memory, which means that the amount you specify is the amount of total MP's you can use at the same time - that's why it is expensive.

This opened up another question in my cluttered little mind, storage memory? The only reference to actual storage memory is A: Offline storage at a 5Y/MPs and the Optical Memory Chips (OMC) at a mere 0,5Y/MPs. That's all.

I know that I can use implanted OMC chips as a storage medium as modified cyberware but what about actual "Storage Headware Memory" It is very seldom one actually use up all that active headware memory if you are a courier so a normal harddrive of some kind would be more fitting.

What do you think? What would a realistic pricetag on such a thing be? 1/10 of the headware memory in cost?

in Matrix, active memory has an x7.5 multiplier, and storage memory has an x6 multiplier. i'd use the same ratio.

OMCs are burn-once chips, like Write-Once Read-Many CD-Rs. They aren't appropriate for storage unless you happen to have a high rating encoder in a cyberarm.

Storage Memory is 5 nuyen per megapulse, plus a nominal fee for the case (I think it's 50 nuyen). I'd imagine that having this datamodule implanted in a body cavity or a cyberlimb would need a DNI or datajack link-up for you to swap data into it.

Why, thank you, Johnny.

OMC's are NOT one-burn chips. Read Matrix description page 54. There are two versions.

1. OMC: Recordable and eraseable blank optical disc.
2. OCC: Optical CODE Chip: These are "burned" chips not eraseable.

Another good description is page 60 under "Storage Memory" where they actually use an Optical Mamory Chip with a chosen MP value. The difference is that storage memory OMC is not limited to 1000MP's.
