Micron 2200 NVME ssd health issue

moxin3 · Apr 11, 2025

I purchased Micron 2200 NVME ssd a second hand OEM drive from marke with less usage at 94% health having 1tb written on it. I have observed it is loosing 1% health after each 2TB writes on the drive. Is it normal? what can i do iam sharing sshot for reference. Hope someone with better knowledge can guide me

I'd say that wasn't bad for a 500gb drive. I find that smaller drives the percentage drops faster than larger ones and it will differ from make to make.

Here is a screen shot of mine for comparison.

Some, if not all Micron drives has a quite short lifespan compared to Samsung Pro drives. About 200-350TB written for Micron, while closer to 1500TBW for Samsung. Your 1% health loss per 2TBW seems to align with the specs quite nicely.

The drive is specified with 150TB endurance. https://www.mouser.com/datasheet/2/671/2200_pcie_nvme_ssd_product_brief-1545778.pdf

2TB of writes should consume 1.33% of that.

Thankyou guys for helping me understand. I really appreciate the help.

One of my older devices, with a 9year old SSD
Was 42days estimated remaining life about a year ago.

WoW thats morale boosting it means it can go till last drop of juice before failing

Ofcouse during this state keep your files synced to an other device. I hope to reach 0% on it, and then see how long it will last after that.
On work we normally have already replaced the SSD.

If you download a lot of big files, beter download them to a HDD, to reduce write actions on SSD.

You highlight "available spare" as 64, but that's the hex value whose decimal equivalent is 100.

can you please explain in a bit simple words iam new to the forum dont understand much terms

The values in that column are hexadecimal, so hex 64 = decimal 100.

Hex to Decimal Converter

Hex to decimal number converter and how to convert. Base 16 to base 10.

www.rapidtables.com

Read it as 100%

So 100% Available spare cells are available.
A cell is used to write data to, when a cell is broken, a spare cell will be used. And so decreasing the available spare cells.

On my disk with 19% health left, i also still have 100% available spare cells.

But why health is shown as 92%

Tester · Apr 11, 2025

92% has to do with Total amount of Write Lifetimes.
As you have 4400gb(4,4tb) of total of 150TB writen to disk that the produces says you can write to it.

For example for my disk i have written 89TB of 100TB produces says you can write to it.

Just an estimation of how much you have written to ssd in total, compaired what the producer says the ssd is capable to do.
However it could fail before it reaches it, or it can last 10, 20TB or more after the estimated time.

You have a higher writes to disk that i have. (daily)
My estimate would be, that you get to about 700days of ssd hours on it, if the writes stay the same as the last period. Your on 21 days now. (511hours)

Thats why i said, if you do a lot of big downloads do it to a HDD directly instead of the SSD, so you can extent the lifetime of the disk.

However if you only use it for 8hours a day, you still get 6years of time with it.

Thanks for the help bro i really appreciate it

The standard for your disk is shown as NVM Express Release 1.2, which I think is quite old. Mine is 1.4. for example.

i bought second hand and its OEM version

Post a new printscreen in a month and tag me in the post.
Will then make a new calculation on your usage compaired with the data now and the one in 31days. So you know what you use, and not compaired with how the first user used the ssd.

SlicEnDicE · Apr 12, 2025

The TBW counter in percent is just a counter for expected lifetime left before you start losing working cells. What will happen after that is that you can start to expect cells to become non writeable. In practice this will only mean you will lose a bit of storage space, but the drive will still function. No data will be lost. The more the drive has lost cells the faster you will lose more cells if you keep writing a lot of data. Eventually you will run out of diskspace.

Health is a simplistic number which seems to be based on the TBW over the Data sheet TBW for endurance(lifetime) given by the manufacturer.
It is the wrong word to use as it has not much to do with "Health".
Why the application designers headline such a number is a mystery.

As already mentioned a much more important number is the number of used replacement cells which are the elements storing the binary data. Once a cell has died that is it for that cell.
Those are replaced by cells from a small percentage of spare cells that are on the chips. So a better measurement is to look at those numbers and the rate they are increasing over time.

In your screen shot the 03 line gives the amount of spares available which is 100% (64 Hex), so no cells have been replaced.

Even the manufacturers App like the Micron Storage Executive use these simplistic numbers for "Good Health" and highlight it.
The only real use is to indicate that the chances of a random failure is increasing with age common to all semiconductor devices.

"The TBW counter in percent is just a counter for expected lifetime left before you start losing working cells. "
It is simply TBW over manufacturers Endurance TBW that is it. Nothing directly to do with starting to loose working cells.
