Also, their submerged in mineral oil aquarium computer was really cool, back in the day.
Apparently a few months ago it became known on the Chinese internet that the 980 Pro, 970 Evo Plus with new controller, and OEM versions are prone to getting unreadable sectors, where SMART 'Media and Data Integrity Errors' increases on every read attempt. https://www.reddit.com/r/buildapc/comments/x82mwe/samsung_ss... https://www.reddit.com/r/DataHoarder/comments/x8arle/psa_sam...

2 -> 3 bit cells is a 1.5x capacity bump. i would not be shocked to find tlc has a >1.5x impact on dwpd.
But it might be easier to find e.g. a 3x sized TLC compared to a 1x size MLC in the FF that GP wants.
I really want to see ssd manufacturers offer a decent warranty... This drive costs $100, and will last 10 years or until 100TB has been written to it, as long as you keep it within the specified temperature/humidity/power conditions. If it fails to do that, we will return $1000 to you.
Lifetime warranties used to be commonplace, I wish we could return to those times, or at least to a time of repairability.
I've been trying to find a decent endurance NVME in the m.2 form factor for write-heavy applications and it appears that true 2-bit MLC has all but disappeared, replaced by 3-bit TLC and higher (with commensurate loss of endurance) The high endurance SSDs appear to be only available in u.2\u.3\hhhl and god-help-me EDSFF form factors Any suggestions? Micron's 7450 isn't readily available

There was one update, but I don't believe it's m.2? [2]

i recommend samsung pm9a3 versions. not as popular, but are enterprise products and also the endurance is like 3 times 980 pro i believe (please check it, not 100% sure). Been using in my threadrupper workstation with a lot of vms which are put to sleep every day with around .25tb written and read each time the vms are started. keep in mind these are 22110 form factor
These are not available with retail support so if you manage to acquire one (which may have been pulled from service with an unknown level of previous wear) you will get ZERO support from Samsung no matter what goes wrong.
I rely on the physical store i buy from where i live. that's the reason i only buy either physically or from amazon germnay (their support had been rock solid in the last 10 years i had been using them).
I installed 2 x 980 Pro 2Tb in a laptop in Nov 2022. Running a daily Robocopy bat script to backup a folder in C: to D: would freeze a couple of times a week and lock the D: drive. After reboot, a drive check would find no errors and everything would work as normal. I've used the same script for years with no issues. Since the firmware update last week Robocopy has not frozen the drive at all this week.
The freeze/reboot/fine cycle seems to be a common one for SSDs acting poorly, running out of blocks they want to use internally, or memory or cache or something, or just hanging in their own firmware for whatever other reason. One of my earlier forays into switching to SSDs, I installed Intel... I think it was 525, 535, something like that, 2.5 inch SATA drives in several different machines. Every one has failed by n…
Given that it's two gen4 drives in a laptop being subjected to a moderately heavy sustained workload, I'd also suspect a thermal problem or maybe even power delivery. Those two slots are probably being fed off the same 3.3V regulator.
Since the firmware bug appears to have caused catastrophic write amplification, what may seem to the user to be only a modest and reasonable workload may be causing the drive that is the backup destination to be running at full tilt doing a ton of writes to the flash and causing the drive to hit its peak power consumption and heat output.
The samsung-made drives lasted about 5-6 years. Everything seemed fine, and then one day you'd get a spinning pizza of death, power down, power it back on...and your SSD was...completely gone. Doesn't even enumerate on the PCIe bus. It's just gone.
Screw the SSD chipset manufacturers for not making sure that their controllers can at least a)still show up on the bus b)be read-only in some sort of recovery mode.
I wish more independent review organizations would conduct destructive "write lifespan until ultimate failure" real world tests on SSDs. With a mixture of real world large contiguous files and small random writes. Real ultimate write lifespan on 3-level-cell and QLC consumer grade SSDs varies wildly for things of the same capacity and similar price. Such as this series of tests from 7 years ago: https://techreport.co…
They should just become read-only, but it seems that in the vast majority, the controller just shuts off and bricks the drive.
Funny thing. This article prompted me to check the health of my two Samsung SSD's (a 250GB 850 EVO SATA III, and a 970 EVO Plus 1TB NVMe), which were fine. But Samsung's Magician also listed my Seagate ST2000DM008-2FR102 2TB spinny disk. It found a SMART error. I ran a performance test and looked at SMART again, and the "Hardware ECC Recovered" value went from 80 to 81, with a threshold of 64. My other software label…
I don't trust Magician to report correctly on other vendor's storage
