[c-nsp] 12.2(18)SXF3 vs. 12.1E

[Joe Maimon]

linear flash sucks and is expensive and small and slow and required for 
use on old bootroms that cant read ata. "sqeeze" after delete 
requirements come to mind as well.

ata flash, cheap, fast, large and supported on most modern 
bootroms/platforms/running image

So yes, wherever you can, use ata flash. Largest one the router appears 
to support, based on REAL WORLD experience (dont believe the specs, its 
oftentimes higher)

Save linear flash for where you need it, like boot helper images for 
rsp's, 1600, 3620 routers so on so forth.
