Hardware parts always come with what seems to be standard naming.

Example for DVD burners :

  • Samsung SE-S084
  • Panasonic SW-9587-S

Is there some standard understanding of these letters ? For example, is the difference between Panasonic SW-9587-S and SW-9587-C the same as any DVD burner called XXX-S and XXX-C ?

Short answer: No.

Each manufacturer has its Marketing-Droids who do invent these numbers out-of-the-blue for each product.

In a product series a higher number may indicate better performance, but that's no rule, just a conjecture.


No. There is no such standard.

Names might be standardised by brand, but even that's only the decision of the company, not a requirement.

  • OK thanks. At least, does a different last letter mean the difference is "less important" that a different number ? For example, should we expect Panasonic SW-9587-S and SW-9587-C to be technically similar ?
