[kwlug-disc] SSD life

[Ron Singh]

So, here's the stats(from TLP)  on my 9yo 1TB Samsung 850 EVO 2.5" SSD in
an ancient TP X220 --
SMART info:
    5 Reallocated_Sector_Ct     =        0
    9 Power_On_Hours            =    21444 [h]
   12 Power_Cycle_Count         =     3917
  177 Wear_Leveling_Count       =       98 [%]
  179 Used_Rsvd_Blk_Cnt_Tot     =        0
  190 Airflow_Temperature_Cel   =       35 [°C]
  241 Total_LBAs_Written        =   33.382 [TB]

Only 2-ish % wear after writing 33TB(on my travel laptop that does do it's
fair share of YT downloads).
The implication, assuming linear wear-down, is that it's good for about
1600TBW, which seems unrealistically high as the drive is only rated for
some 150TBW(as per data sheet!).

I am not a fan of using these things past 7 years, much less 9+ years.
It's is bare-metal backed up on a monthly basis with crucial files stored
on a mirrored private cloud so a catastrophic failure will not be the end
of the world just a few hours of an image restore and re-syncing cloud-y
files.

What would you do? Would you rip/replace? Would you just let it be
considering the silly prices on SSDs these days?
2 days ago, I had to get 2 of a Samsung 4TB NVMe beast with DRAM Cache in
them and paying $1850 each almost made me throw up.
