Add to drivedb: WDC WSH722020ALN6Lz

[joel.neppel]

Hello,
I am Joel, an intern at Western Digital, and I am looking to get a drive added to your database. Unfortunately I do not have an Ultrastar DC HC650 drive to get a log from right now, but I have attached a smartctl -x log from an Ultrastar DC HC620; I hope this works for you.

I also have an entry for you,

{ "Western Digital Ultrastar DC HC650",
  "WDC  ?WSH722020ALN6L[14]",
  "", "",
  "-v 22,raw48,Helium_Level"
},

Here is a link to the data sheet: ​https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/product/data-center-drives/ultrastar-dc-hc600-series/data-sheet-ultrastar-dc-hc650.pdf

Let me know if you have any questions, thank you.

Normally a smartctl -x output with a model name which actually matches the regexp is mandatory to qualify an entry for inclusion.

Device Model:     HGST HSH721414ALE6M0

This model name is useless as a test case. Please provide at least an actual model name which matches the regex.

Question regarding the regexp "WDC ?WSH722020ALN6L[14]":
Do model names with one and two spaces behind WDC actually exist? If yes, what does the space count indicate? If no, the ? should be removed.
