How is wear on the flash storage device mitigated on appliance diskless platforms?

A.
A RAM drive reduces the swap file thrashing which causes fast wear on the device.

B.
The external PCMCIA-based flash extension has the swap file mapped to it, allowing easy replacement.

C.
Issue FW-1 bases its package structure on the Security Management Server, dynamically loading when the firewall is booted.

D.
PRAM flash devices are used, eliminating the longevity.
