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

[RJARRRPCGP]

As i see SATA is loosing it's place now in favor for NVMe ssd's. I don't sell them so much anymore and customers now mostly ask for NVMe SSD's.

I still use SATA, of course. Even when I went to NVMe for the OS SSD.

Does the font on the label of the SSD on my second photo, look odd? I'm wondering if it's a fake.

So after 49 pages are Samsung 870 EVO's still a problem today?

Sure i still use them too, they are still fast and good. But i did mean in general they tend to loose ground.
No i don't think they are fake, fake ones never print the original Samsung on the label. Magician new version can see if it's genuie by the serial number.

Was it a time-related-thing, where shortly after the the manufacturing time of the one with the generic-font, it was changed to the unique Samsung font?

The problem is, that it doesn't even match the 850 Evo font! I suspect one of the 860 Evos, are counterfeit!

Did you look with Samsung Magician, if that program say they are genuine then i think you don't have to worry anything. And most important how to know, if it use the original firmware from Samsung, you are safe. Magician also checks the firmware, then you will be hundred percent sure. No one can copy the firmware from Samsung, that their proprietary sauce secret. Impossible to read out or copy because it's made for that NAND and controller only. And protected against copy or download the firmware.

In the BIOS I was talking about, what's actually AHCI, is listed "RAID" in the BIOS!

Not as suspicious about the 860 Evos. But, I have two of them, with the label of one showing a different origin, which also has a different font!

the logo CE on your second photo looks suspicious . maybe it a photoshoot issue, maybe it looks like a counterfeit (like CE from Chinese Export) or "bad" printed..

Nice catch, but as far as I can see they are all spaced like that.

 

[RJARRRPCGP]

Yes, there's a thicker font on the second one, but the 850 Evos have that too.

You can be sure that your SSD are not fake, they never use the Samsung logo or make one letter different. For example i have seen some fake ones with used Semsung... Many people don't look close and don't notice that. But if Magician says there are genuine, you can be sure of that. If you still in doubt you can open it and see if the controller is from Samsung, no one can copy that. The controller has Samsung on it laser etched. Samsung make their own controllers in house, they never use other brand's. And also the NAND itself has a Samsung logo. In fact all part's used in a Samsung SSD have a Samsung logo on it, they make everything in house.

No one would accept a HDD with bad blocks to begin with, same goes for a SSD. I have too many SSD here, none of them had bad blocks on it. Not even after years of service an TB written.

HDD's ship with bad blocks that are masked out and hidden from the smart stats as general knowledge.

Your "healthy" SSD has a wear levelling count of 6. Same as mine. This is normal wear levelling and refers to dead flash cells. This does not entitle you for an RMA.

no it doesn't, it refers to the amount of times that the disks entire capacity of nand bits have been reset to 0 either through trim or refresh events, it has nothing to do with "dead cells".

on a 4TB drive, all 4TB's of nand being trimmed and data migrated around will consitute a wear level increment.

 

[SPDIF]

HDD's ship with bad blocks that are masked out and hidden from the smart stats as general knowledge.

I know, but they may not develop new ones after you did buy a NEW one, if so you have a bad HDD in your hands entitled for warranty... The same goes for SSD's. That is also General Knowledge...

 

[Hardcore Games]

AFAIK modern SSD from any brand after assembly has some QA testing such as power on and then TRIM is attempted before the SSD is finalized

Once POST is confirmed they are packed in static bags and boxed up for sale. Wholesale boxes of M.2 SSD are usually smaller than SATA boxes.

After noticing that some files on that drive can't be copied to other drives I started digging and found out that my SSD is breaking down. This was probably happening for some time but I haven't noticed.
Warranty replacement is not possible yet so when would this be possible? I'm also doing a full scan in Samsung Magician and it already shows a lot of red blocks.

 

[SPDIF]

It is dying slowly make sure to backup this, think before you loose files. Why would warranty not yet possible? I always send back immediately, and never had problems. Samsung says on it's webpage, NO ANY defects promised? Send back ASAP, clearly warranty case. 1000 bad sectors?? Jeez-es Christ first time i see this. Do not use this SSD anymore before you have taken a backup!

The more you use it, the more chance you will loose files. Send back today and don't wait any longer!!!

 

[RJARRRPCGP]

Bad blocks reported by Magician=Definitely time to send it in!

The files that you were not able to copy are sadly lost forever.

I would hurry up and backup anything that can still be copied to another drive,
that drive is dead and needs to be RMA'ed.


You should also backup your other 870 EVO 4TB as it might just get the same problem.

Hi all. I have Samsung 870 EVO 500GB which is from 2024 .. No issues so far . However the 252 attr incremented from 0 to 1..

What was 252 representing for this model?

 

[SuperConker]

Attribute 252 should mean this:

Newly Added Bad Flash Block:
The "Newly Added Bad Flash Block" attribute indicates the total number of bad flash blocks the drive detected since it was first initialized in manufacturing.


I would recommend installing "Samsung Magician" and check if there are any Firmware updates available for your drive.

After that, I would check the drive with "Hard Disk Sentinel" and post a screenshot here.

 

[massaker]

What was 252 representing for this model?

Read-ECC block count. "from 0 to 1" -> is not anything to worry about.

 

[999cgm]

I am on linux.. so not sure I can have Samsung Magician .. btw the Samsung site says I am on latest..
@massaker any ideea when this Read-ECC increment ?

 

[_roman_]

Samsung and linux support (good joke)

I doubt the smart values are correct or anyone knows if the manufacturer sticks to the specs. Which i doubt

Pre-fail and old_age is just another word for works well

I just had a 2TB 870 Evo replaced under RMA.
Drive failed in daughter's system, became unreadable and make Win10 unusable.
I found UPS to be unreliable at getting the drive there and back as they were scheduled to do so.

 

[chrcoluk]

Brought a 870 EVO on black friday sale planned to be used as proxmox either ZFS L2 cache or in a nand raid with my 970 EVO for a larger nand storage pool for faster VMs,, it failed its long SMART test, initially tested on AMD rig in sig, confirmed on Intel also, swapped cable also.

 

[ajcardiac]

Guess I had better investigate the new unit then if they are still shipping out defectives ones
