Samsung 990 Pro SSD rapid health drops

You only have around 1000 Power on hours on it though, so that might be why.
Issue usually shows up after 2000+ Power on hours (2-3 months of continued use).

The 3x 870 EVO 4TB drives that failed for me all started dying once they passed 2000+ hours.

But up till that point, there were no signs of issues at all.

Also, i would advice people to not fully trust CrystalDiskInfo when it comes to these Samsung SSD failures.....
....Hard Disk Sentinel on the other hand shows a more correct picture of what's going on, and gives the drive a Health of 74%:

I have Hard Disk Sentinel too, so I'll let that keep an eye on it and see what may develop....

If you see any bad blocks develop on it, remember to backup your data.

I was dumb and let it get to 66 bad blocks, and i was no longer able to copy my files
(lost around 250 GB of files because of that).

No worries there. I already routinely make a system image once a month, and separately back up my user files twice a week.

I've just come across this, which suggests the problem with the 870 EVO was limited to the 2TB and 4TB drives, and from a bad batch made in early 2021. If so my 1TB should be safe....

Certain 870 EVO 4TB and 2TB drives are affected by early failures where they develop uncorrectable errors and some data just cannot be read from them anymore.

This seems to primarily affect drives produced in January/February 2021. For example, i have three 870 EVO 4TB, only one is affected (so far), serial number S6BCNG0R207xxxx from February '21.

My 3 drives were manufactured in February 2021, April 2021 and July 2021 and they failed the same way.
This tells me most of the 2021 batches are affected (and not just the early ones).

I see there are people with the same issue on the 1TB model (and even the 500GB model) in that forum thread
(i also see people with batches from 2022 that are reporting having this issue as-well).

not doing much for Samsungs reputation.

any other 990 users got the same readings ?

That firmware has been out for over a year, so most owners of the 980 PRO are running that firmware by now.
(if you are running firmware version 5B2QGXA7 on your 980 PRO, then you are safe).

Not sure why so many news outlets suddenly started posting that again just now in 2023?
