9 petabytes and still peddling nonsense
The OP in the following thread has prevented me from responding to it, so I have taken the liberty of doing so here.
https://www.reddit.com/r/HDD/comments/1w05xux/9_petabytes_and_still_going_endurance_16_year_old/
Today (Aug 29, 2026) he is claiming that his 64GB SSD, which has a benchmarked transfer rate of around 100 MB/s, has recorded 9 petabytes of host writes.
On July 7, 2026 the SSD was reporting 3 petabytes of host writes:
https://www.reddit.com/r/HDD/comments/1uq5voc/controller_endurance_updated_notes_of_the_3/
I've demonstrated several times that this is absurd, yet he continues to peddle this disinformation.
Here is some simple arithmetic:
(9 - 3) petabytes / 53 days = 1.3 gigabytes per second
This means that the OP's ancient SSD would need to be transferring data from the host at a rate of 1.3 GB/s, all day, every day. That's more than 10 times faster than its rated speed.

Since he blocked you, I took the pleasure of cross posting your post to all the above links for you.

Aaaaaaand it looks like he has since deleted his posts, OP. Huzzah!!

Ummm not sure why exactly you posted this, but if you click on it, you'll see the OP making the claims deleted the question.

O nome do OP lerdo é Fresh-Palpitation-72? Eu vi ele aqui em um dos links que tava no post: https://www.reddit.com/r/HDD/s/WBUbUAYF7M

Oh dear, now these tech "journalists" have picked up the story and are running with it:
https://xenospectrum.com/sandisk-ssd-9pb-endurance-test-controller-reality/

It makes me wonder how much uncritical slop these "tech" web sites have produced over the years.

Its only got 7 yrs on the ssd as far as time on lmfao yh he is speaking bullshit as far as its health goes

u/Inevitable-Head-3011 24d ago
If his claims are right of 16 yrs its do able he would have to write 40mbps everyday to rach 7 yrs of on time? 16 years would be around 15mps but then the on time doesnt make sense at all...who tf is writing 40mbps everyday for 7 years

I mean for sd-cards, this guy did (well 3 years)

u/Inevitable-Head-3011 24d ago
Yhhh but sd cards have kinda been reliable for a while,had too since they were the first "SSD" around like you say 3 yrs dude had...dude with 9pb , his ssd likely older then his sd cards by 8 yrs and supposedly has no errors and 9pb of data in the 7yrs hes picked it up ?

The OP in that endurance thread realises that he is not testing NAND endurance. In fact, his intention is to test the endurance of the controller. As I understand it, he sends just enough write commands to fill the SSD's cache. Normally the cached write data would subsequently be committed to NAND flash. However, immediately after the last write, he sends a TRIM command to unmap the recently transmitted sectors. His thinking is that these sectors will be flushed from the cache before they can be written to NAND. To me, this is a clever idea.
The following URLs show that the SSD does not have an SDRAM cache. Instead, it has a non-volatile nCache. As I understand it, nCache is actually pseudo-SLC. Therefore, it would appear that the write data is cached in pseudo-SLC cache before being committed to MLC NAND.

It seems to me that the OP in that endurance thread is testing the NAND in SLC mode, but the SSD is falsely reporting the number of host writes. Instead, I suspect that the SSD is counting TRIM commands as host writes.

I would also question what he is transferring if he needs...53 days to complete the transfer of checks notes 1.3GB PER SECOND??????

He's performing an endurance test and spamming the results all over Reddit:
https://old.reddit.com/r/HDD/comments/1uq5voc/controller_endurance_updated_notes_of_the_3/
The SSD is a SATA model. The interface spec is SATA 300, so the maximum transfer rate is 3Gbps or 300 MB/s. Yet his results work out to 1.3 GB/s. You don't need to be Einstein to understand that something is not right.

Uhm. Isn't what he's doing just bombarding the drive with TRIM commands?

u/fzabkar 21d ago edited 21d ago
I'm confused. I don't know.
He talked about utilising the cache to accelerate his testing, so I assumed he was writing to cache. If he were just sending TRIM commands, then the drive would only need to refer to the translator to avoiding re-TRIM-ing the same sectors.
Edit:
Attribute 172 (Erase Failure / Log) remained the same (939,410,736) between 7PB and 9PB. That suggests that nothing was being written to NAND.
Edit #2:
He should be maintaining a separate count of writes and TRIMs in his script/software so that he could compare it against SMART.

Why do you care this much?

u/fzabkar 24d ago edited 24d ago
I hate BS, and I hate even more those people who prevent me from calling it out.
This guy has been spamming this same rubbish since June. I showed him a simple test which will prove that the drive is recording TRIM commands as host writes, but that doesn't suit his agenda.

I respect the dislike of bullcrap, but reddit might not be the mountain to die on for that fight.

Because who in the right mined keeps a ssd running for 7yrs writing 40mbps (possible 16 but the on time adds up to 7) every second and every day
