Way to much noise here.
The S stamped on the SpecTek NAND is Spectek's logo. The S does not mean the NAND is out of spec.

The NAND seen the OWC blog has the SpecTek logo, and the NAND is seen as PF458 AL.
From SpecTek, the AL grade is "full spec with tighter requirements). In other words, not trash NAND.

Micron spot checks the complete wafer, and if for some reason it fails, they send the wafer to SpecTek. SpecTek then checks each chip on the wafer, and bins the chips accordingly. A few bad NAND chips on a wafer does NOT mean the individual NAND chips that passes as AL spec from SpecTeks tests is poor quality NAND.
