how to interpret SSD information
#1

Do you have a web page that explains how to interpret SSD information?  
My system disk is an SSD drive C:\
I also have a data disk SSD D:\
SIW detects both drives, but there is no drive letter for the D:\ drive.
For the C:\ drive, all the SMART properties are zero, but for the D:\ drive they are not.
I've attached reports from SIW (I hope I did this correctly).

Would you please check https://en.wikipedia.org/wiki/S.M.A.R.T. ?
Please run SIW DEBUG, select "Storage Devices", and send me the generated c:\siw_debug.txt file.

Thanks for the reply.  Debug report is attached.
SIW's SMART output does not seem to coincide with the wiki page on SMART.  
For instance, your "Media and Data Integrity Errors (0E)" is not in the Wiki.
What exactly do your Status and Health properties mean?  These are not in the SMART wiki.

The NVME Express interface defines the "Media and Data Integrity Errors" and the "Health" fields.
Check https://nvmexpress.org/wp-content/upload...tified.pdf

The Status (Good/OK, Caution, or Bad) is similar to the result from the following command:
wmic diskdrive get DeviceId, status

Thanks for the reply and the link for the NVMe document.

Is it a problem that SIW is not recognizing the drive letter for the D:\ drive?
Is there a reason why SMART attribute values are only given for drive1 (SATA) and not drive0 (PCIe)?
They are both Samsung models, but different types.

Can you try Samsung's Magician Software?

Yes, I wanted to avoid doing that, but I have now installed the Magician software.  Over 2300 files and 350 megabytes!  

Over 1800 of the files are eye candy png's.  SIW would have been much better.

Does it show the S.M.A.R.T. info for both disks?

Yes.  Below is what it gives me for the C:\ drive (i.e. PCIe)
SIW seems to be presenting basically the same information as Samsung, both for this drive as well as for the D:\ drive.
The SATA drive data includes attribute values in addition to the RAW data.
The PCIe drive only presents the RAW hex data, which can be converted to decimal.
