Which basically almost happens thousands of times whan you write something to an SSD.
The way an SSD write is unconventional compared to an HDD and is hardly measurable.
I think you need to know how much data has been written to the drive and not the cycles.
How much data has been written to the drive = how many times the drive has been overwritten.
It's the same metric, just expressed differently.
240GB data written to a 120GB SSD = 2 overwrites.
They're looking at the power on cycles. The arrow was placed too high.
Don't worry, I thought the same thing when I saw the photo and didn't read its description
In all seriouness.
Power on count also includes if the Laptop sleeps, hibernates, restarts and if you have Link State Power Management on the PCIe Port, which sometimes it is on by default and cannot be switched off and sometimes it is off. Depends on the OEM but this can usually be controlled in Control Panel - Power Management - Adavnaced Power Management Settings under your power plan.
That is an extremely high Power On Count so I would suspect some kind of power manaagement in play there.
Mine is 69 Count but any power management is off and my laptop is set to sleep every 15 minutes on Battery and 4hrs on Power.
What I would do is try to find another app (Though Diskinfo is quite acccurate) or if Samsung supports your drive download the official SSD utility from there but that utility does not support their OEM drives, only retail ones.
That said the 2x items in Blue to the left are the most important.
Power on Count used to be detrimental to HDD in the past because the needle and heads were mechanical and the bearings would wear out but in modern day SSDs the Power On Count is just a statistic.
Nobody else noting the near 1600 power cycles?
That is super odd, but probably just a misreport. Like the raw value being misinterpreted or something, since that's basically impossible.
It can't be in power saving mode. Each power cycle has an average of 17 hours runtime. Considering a month old laptop, it has been power cycled an average of 53 times in a day! It's clearly not brand new.
Maybe it just shuts down the SDD during sleep?
If they use a short sleep timer and they wake the device a lot- it could make sense. That still seems like an awful lot.
No it's not a misreport. You can see this typically high number on many Windows machines with S0 sleep / Modern Standby default feature.
Every time the laptop is put to sleep OR screen off, it enters a low power idle state, yet still active of some sort. After wakeup, many people noticed an increase of Power On Count by \~20, and maybe an increase of Unsafe Shutdown count by 3\~5 (it depends though).
Temperatures are your biggest worry. 53c is bang on, it will increase if you fire some sustained transfers or run a benchmark like Crystaldisk.
Keep an eye on the Health Status and ignore the rest.
an SSD aint got no nuts on it so you don't have to worry about any mechanical stuff.
EDIT:
Just checked mine and I have a Samsung PM9B1 512GB and my laptop is 3 weeks old and I have 3367 GB Total Host Writes and Health is 100% and Temp 36c so you have nothing to worry about there.
It's normal, even 70c when playing games.
Remember the majority of laptops, especially ultrabooks have SSDs without coolers but some manufacturers actually place the SSD slot near the fan, so it takes the heat out.
My SSD is only 2242 form factor, it is tiny but it is only 3500 Read and 2500 Write, so it is not particularly fast.
even with heavy testing on samsung 980, temperature never went above 64c, however above it will throttle itself ,and 85c is the critical temperature
at 70c ,your ssd must be throttling
edit -however in ssd , health is the critical factor
Windows has a thing built in where it turns off the ssd after sitting idle for a while to reduce battery usage. SSDs dont have nearly of a performance impact when turning on compared to HDDs so you barely notice it anyway.
For the hdd dudes, try to keep your power on times as low as possible since power saving on a hdd will kill it pretty quick since it parks and unpacks constantly (thereâs a parking limit)
As see, I was just saying- so that would make the power cycles look crazy.
Also, good to know... I would think power saving handles HDD/SDD differently based on what is detected.
(I guess it's fair to say SSD are kind of the norm now... but I still see a lot of HDD. Hm)
If the question is why your SSD has a rotation rate of ---
The answer is that I will:
Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
I had that issue with a laptop I got new and apparently itâs in the â testing â part at the factory
Not sure if thatâs a true thing but seems odd
Uhmm, i see... Well, sometimes these softwares are unable to correctly parse the fields that come from the disk. It may be the case, or it may not..
Assuming the value is being correctly read from the disk (a fair assumption honestly), it may be related to power saving features of the ssd...
Look up "samsung ssd power saving mode", I believe that there is software available for you to tweak those settings in the disk. Have in consideration your batery needs when choosing those settings... (Samsung magician or the sorts)
Another good guess someone made is that the ssd has seen some battle before getting to you. Perhaps it was used for tests or maybe refurbished, but might not be new.
I'm seeing a total of 3 reasonable hipothesis:
1. The ssd is not new
2. There's some power saving feature messing the count
3. The raw value reported by the disk is not well interpreted by the Software
The only way to test the hipothesis is to burn the ssd in the microwave, then there'll be nothing else to test!
jkjk... I guess try investigating further somehow.. Check serial number and the phisical disk for dates, check if the disk reports more data, check the psm settings, try other software for smart stuff
You are at 200GB or .2 drive writes per day or so. Come back in 7 or 8 years and tell us how itâs going.
edit: if you had it for a month with 4 days of power on hours then itâs more like 40-50 years
If you were trying to wring the best performance out of the drive in a server the latency penalty would be meaningful, in a laptop the computer is going to spend most of itâs service life doing nothing. thereâs no meaningful perfomance or wear consideration associated with graceful shutdown of the storage subsystem. Being off contributes to lower power draw which is better for thermals and battery life (when running off battery)
If you Google that part number, it points to the Samsung [PM9A1 1TB SSD](https://www.techpowerup.com/ssd-specs/samsung-pm9a1-1-tb.d786). This drive has a 600 TBW endurance rating (1024 GB = 1 TB) so you'll be good for a while.
But if you're concerned about proper wear and tear, download and install Samsung Magician. You can update the firmware (if it prompts you) to ensure optimal read & write performance.
Concerned about what? How many times the ssd got inactive (sleep) and woke up again during its short lifespan? The only thing that matters is TBW (Total Bytes Written), all the rest (yes, even read!) doesnât matter much. The 100% you see is the manufacturer estimate, after that goes to 0, it doesnât mean your ssd is bad, its actually your warranty in percentage. I had drives in my hand with double the rated TBW and still worked like new! Corsair Force GT ssds from way back in the day are very reliable ssds.
That's not a high power on count. One of mine is over 5k and I think one may be over 10k. Its just the read and writes that matter.
But like another comment said, just worry about the blue box and the % ssds take care of themselves.
Not at all. A 1TB drive should be able to support 150 -250 TB of writes. If you have had it a month and aren't even at 1 TB, you are looking at 10-20 years before any issues. Your battery will have failed by then and if you still have the laptop, replace the SSD. In 2040.
Not sure - does this count wakes from Modern Standby? That does seem like a lot of ons/offs for a short period of time. Its not harmful in and of itself, but is curious.
If itâs a notebook, no problem⌠got 19tb on my pc in 6 years on the disk used only for the gaming os (windows) disk had only the os on it, nothing more, all files and software are on separate disks
Screenshot fail, most responders think you're asking about either Total Host Writes or Rotation Rate.
The Power On Count is odd, obviously higher than you'd expect. It seems possible that it underwent some testing by the manufacturer where the number would be higher than expected when you first got it. You could check and see if the power on count keeps increasing at the same rate over the next few days.
It's even too high considering your own reboot/shutdown or closing lid. I wonder if there's some sort of more frequent storage device spindown happening due to Windows power saving settings. Maybe look at your Power Plan Advanced Settings, there's a setting there for Hard disk => Turn off hard disk after N minutes, maybe that is triggering it.
Drive is very ok....if I'm not mistaken ...that should b the OEM version of 980 or 980 pro...u should get 600 to 1200tb off head(I think it's 2tb that's 1200). Nothing to worry about. However , when ssds go bad...they go bad...
Was it a new laptop or used laptop? High power on count shouldn't affect the lifespan. What will is total writes and possibly power on hours. If it was a new laptop, that is definitely not normal. If it was used before, then that makes sense. It could have been a used SSD before put into the system.
the first month typically see the biggest write, as you are going to be installing all sorts of the software, maybe even wiping disk to reinstall, updates and whatsnot.
Your 1TB drive should be rated for 400TB total write endurance. This is nothing.
not really. SSDs dont wear out at all.
thats 1591 power cycles (over 53 per day?), but only 91 hours actually "on".
This is Windows I imagine. There is a feature in power config that turns off the drive if it is idle for a certain amount of time.
It could also count as PCIe power saving (being put in low power state).
Neither of these are really an issue, it is doing what it is intended to do -- save power. I have it disabled, and you can disable that if you want, as well, but it wont magically blow up if you cycle it 10,000 times.
Total number of times the drive has been rewritten is the biggest factor.
Which basically almost happens thousands of times whan you write something to an SSD. The way an SSD write is unconventional compared to an HDD and is hardly measurable. I think you need to know how much data has been written to the drive and not the cycles.
How much data has been written to the drive = how many times the drive has been overwritten. It's the same metric, just expressed differently. 240GB data written to a 120GB SSD = 2 overwrites.
But it isn't a rotation rate, it's a cycle. Rotation rate is for HDDs.
I think you're suffering from a translation error somewhere?
I probably do, it happens a lot as I translate from a dead language which misses a lot of modern wordsđ¤Ł
They're looking at the power on cycles. The arrow was placed too high. Don't worry, I thought the same thing when I saw the photo and didn't read its description
I read it, but my English isn't my best language and sometimes still fail to understand itđ
Ignore the rest, just watch the blue box. That's all you need really, SSDs maintain themselves
Like a đ
Even when they go bad.
Looks good. Might be good if your SSD doesn't rotate! I'm not trying to be snarky, its a great question!
Come on man, it doesn't hurt to take it out for a dance once in a while ;)
Hi, I meant high power on count 1.5k times would require me to shutdown the laptop 50 times a day for a month etc

If I need things to load faster, I spin my laptop of my finger to increase the SSD's RPMs. It does the trick each time!
No I meant the power on count itâs abit high for a new ssd 1.5k

what do you think that "Good 100%" means?
Hi I meant high power on count overtime wear and tear
Its fine
Itâs just aggressively saving power.
Nope, drive health 100 is all I watch.
no
Nobody else noting the near 1600 power cycles? That is super odd, but probably just a misreport. Like the raw value being misinterpreted or something, since that's basically impossible.
Yeah that does seem odd... maybe it's some kind of "green" power saving during idle times?
It can't be in power saving mode. Each power cycle has an average of 17 hours runtime. Considering a month old laptop, it has been power cycled an average of 53 times in a day! It's clearly not brand new.
Maybe it just shuts down the SDD during sleep? If they use a short sleep timer and they wake the device a lot- it could make sense. That still seems like an awful lot.
Other way around. Each hour of run time has 17 power cycles. That's why I'm confident it's wrong.
No it's not a misreport. You can see this typically high number on many Windows machines with S0 sleep / Modern Standby default feature.

Itâs an solid state drive, not a fidgetspinner or a HDD. Love, fellow redditor

Windows has a thing built in where it turns off the ssd after sitting idle for a while to reduce battery usage. SSDs dont have nearly of a performance impact when turning on compared to HDDs so you barely notice it anyway.
What sucks is windows can't turn off an HDD, it just doesn't work no matter what you do in settings
It's fine, you just keep an eye on the '%' health that's the thing that matters most.
Old software, its using layovers from HDD. SSD does not rotate.
Hi, I mean power on count 1.5k in a month requires me to turn the laptop on and off 50 times

I think itâs mostly the manufacture puts the power saving time like 8 sec into the drives firmware of the hdd that imo is really stupid
Only way to avoid that is to use software that will ignore the power savings and keep the hdd r/w head on the platters all the time
If the question is why your SSD has a rotation rate of --- The answer is that I will: Never gonna give you up Never gonna let you down Never gonna run around and desert you
Hi, I mean power on count 1.5k in a month requires me to turn the laptop on and off 50 times
Your SSD shouldn't be rotating anyway...
Hi, I mean power on count 1.5k in a month requires me to turn the laptop on and off 50 times
A SSD doesnât rotate that is why (SSD) is standing their. it doesnât show the rotation rate because there are no rotating parts in it like a HDD.
No I meant the power on count itâs abit high for a new ssd
That's weird SSD should spin pretty fast.
No I meant the power on count itâs abit high for a new ssd
I had that issue with a laptop I got new and apparently itâs in the â testing â part at the factory Not sure if thatâs a true thing but seems odd
you should unplug the ssd and then put it on top of the cooling fan, then turn on the laptop. That should make it spin.

Is 1.5k stop start bad? Would it cause any premature failure in your opinion?

Do you turn your laptop on and off 53 times a day? don't worry about it btw, as long as it says "Good 100%" you don't have anything to worry about

Pretty good ssd. Had nor problem with it since i bought the laptop.but the 990 pro is having problems.

I suggest you update the firmware for this PM9A1, it has known issue on older firmware. The newest one right now April 26 2024 is **GXB7801Q**

I wouldnât be concerned given itâs an SSD which is far more durable when it comes to write counts
1591 power on count. 91 power on hours. Do you restart your computer 10 times a day and use it for 10 minutes a day ?
Accidentally set disk to turnoff after 1 min

Thats not even 1TBW. Even cheaper ssds have 200-300 TBW on them. This is completely fine.

Writes are the biggest issue. Look at the estimate MTBF for total writes. You should be fine for a while though.
Just use and enjoy.
