Most users run the MPTool in default "High Speed" or "Normal" mode. This gets the drive working, but it leaves performance on the table. | Metric | Standard Factory Drive | Extra

What is "Extra Quality" (often labeled as "High Level Formatting" or "Original Tier" in Chinese translation)? Most users run the MPTool in default "High

"Extra Quality" is a specialized production setting that forces the controller to perform a 3-pass verification on every single NAND cell.

[Test Item]
Check Flash Type = Enable
Low Level Format = Enable
Verify All Blocks = Enable (Critical)
Verify All Blocks Count = 5 (Extra Quality: 10)
Enable High Speed Verify = Disable (Slower but thorough)
Enable ECC Verify = Enable
ECC Threshold = 12 (Default 24. Lower = stricter)
Enable Random Read Verify = Enable
Random Read Pass Count = 3

Why this matters: A standard tool runs 1-2 verification passes. Extra Quality runs 10 passes with lower ECC tolerance. This detects weak bits that would otherwise cause data corruption after 6 months.
