From (of all places) TigerDirect. With shipping to Washington, it comes to $33.48. Any idea on the media code and quality on these?
If they’re not Verbatim or Sony MIS, then the quality is sub-par. These are most likely CMC MAG D04 or RITEK S04, or something similar. There are only a few 8x DL codes, and all the brands use the same ones. Not much to think about, not much variety, and all pretty much the same mediocre quality.
Here you go this will give you an ideal of what the MID is
