New Crucial M500 S.M.A.R.T. attributes for MU03

Reported by: Peter Wu Owned by: Christian Franke
Priority: major Milestone: Release 6.3
Component: drivedb Version: 6.2
Keywords: Cc:

Description

F7 and F8 are taken from:
https://www.micron.com/-/media/Documents/Products/Technical%20Note/Solid%20State%20Storage/tnfd23_m500_smart_attributes_calc_waf.pdf

F7 is the number of NAND page program operations initiated by the host.
F8 is the number of NAND page program operations by the FTL that are done in *addition* to the host writes.

These can be used to calculate WAF = 1 + (ΔAttrib_F7 / ݈ΔAttrib_F8)

Attribute F6 (246) is taken from
https://www.micron.com/~/media/Documents/Products/Technical%20Note/Solid%20State%20Storage/tnfd21_m500-mu02_smart_attributes.pdf

Updated patch:

  • Shrinked names for attributes 247 and 248 (otherwise it would misalign in the output)
  • Added attribute 210 (Successful Redundant Array of Independent NAND (RAIN) Recovery Count)
  • Renamed attribute 202 (Perc_Rated_Life_Used -> Remaining_Lifetime_Perc), the value shows the Remaining Lifetime Percentage while the raw value is the inverse of it.

This applies to device Crucial_CT480M500SSD1 with firmware MU03. This is
how it looks like:
