Is the 1-TB WD 2.5" Black internal drive going end of life?

My company uses the WD10JPLX drives in one of our products, but we’re having a number of resellers tell us now that the drive is no longer available. But WD is saying nothing on the website about the product being discontinued???

I don’t care what the politics are, I just need drives…

Are you, for some reason, “married” to that particular model?

Not particularly. What we are married to are features and performance which we can’t seem to match in another manufacturer:
2.5" SATA
7200 RPM
6 GB/sec
0-60°C Operating Temp… we’d actually prefer 0-70°C
Can’t use SSD; write cycles (3000) are far too low for our application.
