x8dtu – main ssds: how worn are they?

Let’s look at these two SSDs (full smartctl output appears at the end).

  pool: zroot
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
	The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
	the pool may no longer be accessible by software that does not support
	the features. See zpool-features(7) for details.
  scan: scrub repaired 0B in 00:03:53 with 0 errors on Mon Jul  7 03:51:20 2025
config:

	NAME        STATE     READ WRITE CKSUM
	zroot       ONLINE       0     0     0
	  mirror-0  ONLINE       0     0     0
	    ada1p3  ONLINE       0     0     0
	    ada0p3  ONLINE       0     0     0

Interesting notes:

  1. Both have 35857 power on hours
  2. 51078678193 logical sectors written (or 51078652989 for the other one)
  3. Wear_Leveling_Count is 266 or 255 – no idea how to interpret that

With 512 byte sectors, that means these drives have written 51078678193 x 512 or 26,152,283,234,816 bytes. Or about 26,152.28 gigabytes, roughly 26TB. Please check my math (full smartctl output appears below).

Looking at the Samsung page, I see “Warrantied TBW for 860 EVO: 150 TBW for 250 GB model…”.

This tells me I’m about 1/6 of the way through the drive in terms of TBW.

As pointed out by Thomas A. Frederiksen, Percentage Used Endurance Indicator is at 15%. Which is pretty damn close to 1/6.
