SSD health drops after some few week of usage.

[Kim1738]

I recently purchased a Kingspec m.2 2242 SSD. It was performing well for the first few days, but after some usage, the health quickly lowers to 99%. I assumed the temperature would be the cause, so I continued using it until today, when the SSD's health reduces to 98%. Should I be concerned given that the SSD's power on-time is only 492 hours i.e 20 days and 11 hours?

Seems normal, and is probably based on the amount of data written. When you just get a new one you write a bunch to it, more than you'll do afterwards...

What's the TBW spec on the drive?

Buy cheap, get cheap nand. Can't find much positive about this brand.

 

For comparison sake;

Here's my 240GB OS drive, with over 20x the number of writes and 37x the power on usage. Down to "only" 85%.

 

 

But seriously, don't believe this software "health" stuff.
I have some old SSDs that supposedly "died" at 0% years ago and I can still read/write stuff on them.

I don't know what they base it on, but it's not off total host writes nor time.

My drive is rated for 400TBW. This means, with 31.5TB written currently, I would realistically be at about 92% just from the writes alone.

As for time, it's rated at 1,800,000 hours. Or 98.9% based on my current power on hours. Adding the two, I'm still far from 85%.

90TBW.

That's low, but then it matches your reading.
