Samsung 870 EVO - Beware, certain batches prone to failure!

Unfortunately, I have similar experience with the EVO 870 4TB drives, with two failing consecutively. I used one as a backup drive but after a year started having issues. It was not clear to me then that it was the drive failing. I just saw intermittent device disconnection notifications on Windows but could not identify the cause. Then when I was upgrading to Windows 11, I noticed the 870 EVO kept disappearing/appearing on my Drives list. File transfers also kept getting interrupted or failing.

Incidentally I sent my system for repairs for other issues and the staff replaced the drive with another EVO 870 as it was identified as faulty. It's been less than a year since, and I wrote about 1 GB worth of data to the drive, but now it looks like it has issues too. Some files could not be moved nor opened. I ran Samsung Magician which said the drive was in "Good" health. The short scan ran fine, but the Smart tests kept failing/aborting with no recovery options. I tried firmware updates, but that also kept failing for the EVO. Did some Googling and it looks like the EVO 4TB has some bad batches.

I think my next replacement backup drive will be the Crucial MX500; rather not gamble on another EVO bad batch...
I had 2 4TB drives go wrong, and dont even want to use the replacement 4TB drive they sent me back, even thou it was sept 2022 made.

My brother in law just asked me about upgrading his laptop's storage and told me he had his eyes on a 1TB 870 EVO, so I immedeately thought of this thread and told him to wait. Just had a quick glance through the pages and from what I gathered certain 1TB drives fail as well. So I should probably tell him to get something else, just to be safe, right?

I've always bought Samsung, but just had my 2TB 870 EVO fail (manufactured Jan 15 2021in Korea, so admittedly lasted longer than others here) and am now uncertain about what to replace it with.

Do I give Samsung another chance and hope a newly produced unit with up-to-date firmware is ok? Or do I switch to another brand? What do others recommend? I've always had good luck with WD HDDs but not much experience with their SSDs. Or SanDisk?

I guess I could grab another NVMe, but haven't decided whether it's worth it.

I think that the source of this problem may be the same as the 840evo.
The 840evo bug is explained on the site below.
Read on to understand the problem with the 870evo.
840evo seems Samsung has finally disclosed the details of the source the bug.
Will Samsung disclose what's causing the 870evo's problems?

Most modern file systems still show significant aging with performance loss, especially on newer storage technologies like SSDs. If SSDs or even faster devices are to be used to their full potential, additional solutions are required. Even when using several strategies to limit inter-file and intra-file fragmentation, current file systems often fail to achieve the physical locality required to retain performance in the long term. Even though these problems have been ignored in the past, there have been some promising current developments. At first glance BetrFS and ZFS seems to be largely immune to aging and thus merits further investigation. However, the windows10/11 NTFS and exFAT file systems are very susceptible to aging.

You can see a lot of 870evo S.M.A.R.T data here.
Look at the updated data today.
A surprising number of SSDs have bad blocks.
If this data is true, it seems that a problem occurs with a surprisingly high probability.

I have 3 Samsung Pro 2TB.
They say 97* Good / 100% Good / 99% Good
870 EVO 4TB Brand new is at 99% Good

No No error counts that I see, what else should I be looking for?

Also, odd Question, how did you guys get your Raw Value column to only show the #'s vs lots of 0's in front like mine? Couldn't find the option

If you have anything but raw value "0" in the ones mentioned by the OP then you may have a affected SSD.
Check your 870 EVO SSDs for these things:
Elevated "Reallocated Sector Count", "Used Reserve Block" and "Runtime Bad Block" count - first warning sign (my two other 870 EVOs have none).
Non-zero "Uncorrectable Error Count" and "ECC Error Rate", and especially if those two keep rising when you read/write files. Definitely affected then!

I like how Samsung has been sweeping this obviously systemic problem with one of their late model SSD's under the rug and this whole debacle has me doubting the reliability of my 870 QVO 4 TiB.

I'm REALLY glad I came across this threat (oops thread) before I bought my 4 TiB 870 QVO -- because I had been about to drop the hammer on a 4 TiB 870 EVO!

Hi,
EVO would be a better buy ordinarily but this 870 series nonsense killed that.

Slightly off topic, but what is the difference between a QVO and EVO?

Are their actually "dead" SSD's from in this thread?

Just saying because I haven't read this officially from Samsung on any tech site.

Thank you! I should've googled it, but there is so much knowledge on here, I forget to, lol.

I have deleted the link of my previous post, because they weren't correct about the PRO drives...

Yup, mine died due to bit errors 2 weeks ago (diagnosed by a data recovery company). I couldn't load Windows until I disconnected this drive (my secondary SSD)

Luckily I was able to recover everything and move it onto my new drive. And it prompted me to finally setup my home NAS for backups.

But this is not just weird readings. I didn't even know about this forum thread until after my drive died. I might have even bought another 870 to replace mine, if I hadn't found this thread.

why is samsung not doing recalls?
Maybe the batch size of affected consumers - while noticeable - is not significant. I mean, even the retailers (PC builder type) should be aware of the problem right and maybe recommend something else or provide a disclaimer. But so far I see only some users having issues and reporting them. Others may have better batches or RMA a bad one and got a new one so they don't bother.

"Colour me with sadness when within just a couple of days of buying the 990 Pro 2TB, I noticed that the drive health according to SMART data from both Samsung Magician and third party tools had dropped to 99%. For the record I have other Samsung SSDs with over 40TB written and still at 99% health 1.5 years later, so I knew this was not normal.
Within another day or so it had dropped to 98%, by this point I'd not even written 2TB to the drive. Fast forward a couple more days and the drive health was sitting at 95%."
