SSD Write Endurance 25nm Vs 34nm

[Christopher]

Thank you! I'll try it later today.

Ohh... what does it do? I wonder if it works with the Imation branded MTRONS.

Hi B.A.T, please find the file attached. it is the special tool for Mtron SSD. (Smartview)

Sadly it doesn't recognize the Mtron. I don't know why.

It makes it possible to get more accurate info from the Mtron.

Maybe it needs to be in IDE mode and not AHCI?

[B.A.T]

That is a good idea. I'll try that tomorrow.

Hi B.A.T , maybe the firmware version on your Mtron drive is too old, both of my Mtron 3025 have the version 0.20r1 and working fine. Sadly the Mtron website down and very hard to find the correct version firmware now.

[Christopher]

Some of mine have 17r and some have 18r, but the latest available for mine (they're Imation branded) is 18r.

Please find the 0.20r1 firmware links.

This firmware package support all Mtron SSD.

B.A.T. --

I'm excited -- I love those damn irritating MTRONs.


The erase count is literally the number of erases (I think it's in 1MB chunks). My 16GB MTRONS would decrease MWI around every 15 000 000 RAW. Unfortunately, because the drive is always doing GC and wear leveling the number is always increasing even if you're not writing to it. You could fill the drive to 100% look at before and after SMART shots, then erase the drive. The Samsung 51nm SLC is rated for 100K PE cycles, so 1 MWI should be 1000 PE cycles. 1000 * 32 768 MB = 32 768 000. Something like that, anyway.

The maximum raw value is 3 200 000 000 for the 32GB, should be 1 600 000 000 for the 16GB (but I have no way of verifying what the hell happens when you get that far).

Your drive is probably ~98.4 MWI if you want to think about it that way.

Writing a 1GB file to the PRO isn't going to tell you all that much. If you do it a couple times, it will be different each time.

I also think I have the .18R FW for your drive, but I would avoid flashing it like the plague. It's not like 4K RWs are going to skyrocket from 0.45MB/s to 0.50MB/s. But I get 46MB/s QD1 Random Reads with my PROs though. So that's nice, and you should be able to get a high avg speed.

I think you are right about how it shows write.
1GB file increases the raw with 1200~1024 MiB
Filling the entire drive with 29.3 GiB increased the raw with 50000~48.8 GiB. That is a lot of writes in WA. It'll be exciting to see how long it will last.

[Christopher]

I hope your MTRON lasts longer than the two I tried -- remember -- don't short it out! All I have to show for it is two dead MTRONs and a trail of tears.

[B.A.T]

How did you manage to do that? It's secure in the endurance rig so there should be no problems.

Ha... I didn't say I was proud of the fact. And if I've proven anything, it's that no SSD is safe and secure when I'm around.,

Needless to say, the poor MTRON got shorted out because of something dumb I did. I had run it for a day or so in my other system before I put it in the endurance rig, and I managed to short it while moving it. It was a combination of rotten luck and bad decisions on my part.

The other MTRON died after some time, I rebooted the system and the MTRON had locked up. I tried flashing new firmware on it, but to no avail.

If I can track down 20r FW for the 16GB 7025, I'll give it another shot.

[B.A.T]

Do you know the difference between 17R and 20R?

[Anvil]

Just a quick update. (busy with the new releases from MS for a few more days)

You may have noticed that the Samsung is Off the chart, it's currently at 1764TiB but as the other drives are way behind I've set a maximum of 1500TiB.
The chart in post#1 will be correct though.

Some thoughts for new charts which I would consider useful if possible: split the big chart on sections based on SSD capacity like <100GB SSDs, 100-200GB SSDs, etc. Also, maybe a more useful chart would be one in which total writes potential would be presented, normalized relative to a theoretical bigger SSD. In such a chart, a 40GB SSD with 1PB writes would be presented to have a theoretical write potential of 7.5PB relative to a 300GB model ( TotalSSDWrites * (300GB/SSDSize) ) . And for the dead ones, one extra information would be useful where it is possible to get it: average number of P/E cycles per day next to total writes. This should tell us if a slower write speed makes a difference or not.

[Christopher]

I hope the M3P lives long enough to throw off the chart scale as well.

Am I imagining things, or did the M4 go from 33 erase fail and 0 program fail to 33 erase and 26 program failures like 4 days ago? Hmm. I wonder if that just means it just had to try a couple times to erase or program, but no blocks were taken out of service.

[B.A.T]

You have good eyes. I missed that one. It changed to 26 between 29th and 30th of may.

[Ao1]

Just for amusement (and with no expense spared) a 4 GB unbranded USB drive. No SMART info.

Assuming 1,000 P/E cycles @ 2.5 MB/s it could in theory last 19 days.

[Christopher]

A01,

Do you happen to know what manner of flash is up in there? I'm sure when it dies you can pry it open. All things considered, 2.5 Mbs isn't terrible. It's not much worse than the 32GB PS 100 Phison I tried.

My Intel 520 is up and running again.

No issues to report with it after it's retention test.

I'll have a look at it, the "old" charts made by Vapor would have been great as well.
(unfortunately there is only so much time available)

@canthearu
That is great news!
