Application-accessible nvram/cache for Linux?

[Drew Van Zandt]

Flash hard drives are out there, that's close... I saw SRAM-based hard
drives once upon a time, but that was so long ago I don't know if they still
exist.

These are small but purchaseable: http://magicram.com/industrial_sram.htm
There are solid-state hard disks, SATA interface or IDE:

Fibre-channel:

...

and this is interesting.
