RE: TRIM vs UNMAP vs WRITE SAME and thin devices

Adding my 5 cents.

T13 added Trim to the latest ATA8 proposal.
http://www.t13.org/Documents/UploadedDocuments/docs2009/d2015r1-ATAATAPI_Command_Set_-_2_ACS-2.pdf

This is after the changes put into the definition, with 'Deterministic Read after Trim'.
This is not STANDARDIZED, but pretty much excepted by all sides.

I was hoping that would settle the differences between T10/T13 on this - little did I know...

We are working with David W. on his implementation for Trim feature, and hope to get to the bottom of debug process soon.
Hope to update soon...


Regards,
Eyal Shani.
