Hi, This is my first post on this forum. Thanks for all the good information.

I have a PNY CS900 480GB SSD newly installed as a system drive on a Windows 10 22H2 desktop and it's performing fine. I have read some less-than-favourable comments about this SSD, but that is not the subject of this post.

I have been looking at the S.M.A.R.T. data returned by this drive (Crystal, HWiNFO64), and I'm puzzled about some of the attributes labelled as "Vendor Specific" on Crystal. I have no questions about many of the well-known attributes such as Power-on hours, power cycle counts, temperature, etc. However, there are two undocumented attributes D2 and D3, which are steadily increasing with time, more-or-less in line with Total GB written (F1) and Total GB read (F2).

For example:
Total GB written (F1) = 94, Total GB read (F2) = 110, D2 = 8, D3 = 5
F1=96, F2=116, D2=8, D3=5
F1=103, F2=126, D2=9, D3=6
F1=121, F2=169, D2=11, D3=9
F1=124, F2=181, D2=13, D3=9
F1=127, F2=191, D2=14, D3=10
...

I have two questions for any of you with good knowledge of this SSD:
(1) What are the D2 and D3 attributes ? I got no answer from PNY.
(2) This drive doesn't seem to report a "lifetime remaining" in S.M.A.R.T., for example E7 which is used by several drives.

Many thanks for your help.
