Please add WD Blue PC SSD to the DB

[Attila Fazekas]

The related smart data was published in the WDSSDDashboardSetup.zip downloadable from
​https://support.wdc.com/downloads.aspx?p=279 .

.rsrc/BIN/41 .rsrc/BIN/42 xml files contains the SSD related attribute names and IDs.

I added the following entry to my drivedb.h .

  { "WD Blue PC SSD",
    "WDC WDS...[TG]1B0[AB].*",
    "", "", // all extra attribute is raw48 until otherwise proven
    "-v 165,raw48,Block_Erase_Count "
    "-v 166,raw48,Minimum_PE_Cycles "
    "-v 167,raw48,Max_Bad_Blocks_per_Die "
    "-v 168,raw48,Maximum_PE_Cycles "
    "-v 169,raw48,Total_Bad_Blocks "
    "-v 170,raw48,Grown_Bad_Blocks "
    "-v 171,raw48,Program_Fail_Count "
    "-v 172,raw48,Erase_Fail_Count "
    "-v 173,raw48,Average_PE_Cycles "
    "-v 174,raw48,Unexpected_Power_Loss "
    "-v 230,raw48,Media_Wearout_Indicator "
    "-v 234,raw48,NAND_GB_Written_SLC "  //233 NAND GB Written TLC
    "-v 241,raw48,Total_GB_Written "
    "-v 242,raw48,Total_GB_Read "
    "-v 244,raw48,Temp_Throttle_Status "
  },

It seams to be working on my:

=== START OF INFORMATION SECTION ===

I narrowed the regexp to the ​https://www.wdc.com/products/solid-state-drives/wd-blue-ssd.html , but IMHO it could be added to all "WDC WDS.*" at the moment.

Thanks.

Please provide a full smartctl -x output of this device as an attachment.

230 Media_Wearout_Indicator -O--CK   100   100   ---    -    47244640267
...
233 Media_Wearout_Indicator -O--CK   100   100   ---    -    835

It is possibly better to use raw16 (11, 0, 11) or hex48 (0x000b0000000b) format for attribute 230.

Attributes 230 and 233 have same name but different raw values.

[Attila Fazekas]

The xml from WD names the 233 differently!

"233" is "NAND GB Written TLC"
"234" is "NAND GB Written SLC"

Both value is close to the
241 Total_GB_Written or Host_Total_GB_Written.

[Attila Fazekas]

"It utilizes a SLC cache technology" (I just read in article, the spam protector prevents me to link it)

It explains why I have both TLC and SLC attribute on the same device.

The content of the 2 xml:

[Attila Fazekas]

In the new patch I tried to match the db file style, and added some commented attribute.

I changed the 230 to hex48, the value does not changed today, it does not seams to be something frequently changing/counting.

Added the TLC suffix where it made sense.
Total_GB_Written replaced to 'Total_Host_GB_Written' to be more similar to the vendor's xml name.
