Pulling Terabytes Written from Samsung SM825 SSD

[The Gecko]

I own three Samsung SM825 SSDs (200GB). The SMART details I can pull off my FreeNAS system are as follows:

Code:

There are a number of attributes missing from this list. I don't see anything pertaining to written LBAs. Does anyone have any experience determining how much has been written to an SM825?

This is a question for Samsung. :P

Both my 830 256GB and my 850 Pro 512GB use attribute 241 as "Total LBA written", so Samsung clearly changed the SMART data around the time the 830 was released.

None of the SMART values on that list look like something of the sort (unless the drive is brand new).

So yeah, question for Samsung.
