Summary: SHGS31-1000GS-2SHGS31-1000GS-2 (SK hynix S31)

Could be added to existing entry SK hynix SATA SSDs.

PS: Please do not set the Milestone in future submissions.

From what I saw in the SK hynix SATA SSDs section vs. the data sheet the attributes do not all line up (they mostly do but not 100%).

comment:3 Changed 7 weeks ago by Christian Franke

SSD vendors continue to invent new attribute variants. Due to the very long drivedb backlog, I usually avoid extra entries for each new minor model/firmware difference.

comment:4 Changed 7 weeks ago by dak180

I would tend to classify different units for a value as a noteworthy difference.

Milestone: Release 7.3unscheduled

Please be more specific and list the important differences here.

241 & 242 are in GB rather than GiB.

170 & 173 & 231 & 243 & 250 are not present (not sure if that matters).

233 is listed as "Normalized Media Wear-out" which is defined as "The number of average erase/program cycles to indicate of imminent wear- out (Counting down from 100 to 1)"

234 is listed as "NAND GB Written" which is defined as "The number of programed pages".

I think those are all the differences between the section you linked and the drive's data sheet (linked in the description).

241 & 242 are in GB rather than GiB.

The meaning of 'G' in this context is not cleanly specified in the Spec. If it means the SI prefix, it may also be the case for the other drives covered by this or the second entry. The actual unit could be determined from a smartctl -x output from a drive with more than ~44000000 Logical Sectors Read/Written in Device Statistics. GB and GiB ranges do no longer overlap then.

170 & 173 & 231 & 243 & 250 are not present (not sure if that matters).

It does not matter. If it would, drivedb.h would be N times larger for some N>2 :-) The sets of supported attributes may differ even between firmware versions for the same drive.

233 is listed as "Normalized Media Wear-out" which is defined as "The number of average erase/program cycles to indicate of imminent wear- out (Counting down from 100 to 1)"

Media_Wearout_Indicator from DEFAULT entry matches closely.

234 is listed as "NAND GB Written" which is defined as "The number of programed pages".

Lifetime_NAND_Prg_GiB means the same (if GB is actually GiB). The second SK hynix SATA SSDs entry (see #1181) may be a better match.

I could do a big rant on not specifying units and I am sure you could too so I will not.

I will attach the output of a drive over the threshold.

Lifetime_NAND_Prg_GiB means the same (if GB is actually GiB). The second SK hynix SATA SSDs entry (see #1181) may be a better match.

Assuming GB is actually GiB than the first would match better because 234 is the only overlap (with an unknown attribute) whereas the second has several missing as well as numbers that mean different things (180 being the first I noticed).

Thanks for the output. Values do not match, GB comes closer:

241 Total_LBAs_Written      -O--CK   100   100   000    -    903
242 Total_LBAs_Read         -O--CK   100   100   000    -    180
...
0x01  0x018  6      1765533946  ---  Logical Sectors Written
0x01  0x028  6       352246877  ---  Logical Sectors Read
1765533946 LBAs: 841 GiB, 882 GB
352246877  LBAs: 167 GiB, 176 GB

Replying to Christian Franke:

Does that mean a separate section then?
