Close. Both drives are identical but during production they are tested 
as RLL, and if they pass they get an ID/230 sticker and marketed as an
RLL drive in the catalog. If not ID/130 goes on and it is marketed as 
an ID/130. (Look in any catalog that used to carry Priam). The key point
on these drives is the quality of the media (chromium instead of iron
oxide). I've got many ID/130's running RLL ok and a few with a bad sector
popping up every few month's. BTW, I can just about throw a stone from 
here to PGI, and many of the Priam installs I see were from there.
