This is scaring me because it means my fairly new 1TB SSD is gonna die and fast, it will even go as high as 80 C. My other SSD and regular hardrive all show as 33 C .... I am getting these readings from the S.M.A.R.T. section in the Asulogics Disk Defrag application. I noticed the light indicating activity will stay on for a long period of time even tho it should not be doing anything. I have no idea what to do any advice would be helpful 🙁 BTW every reading shows up as fine, and I am able to run games off it... but this is probably killing it faster, and also doesn't make sense it would be hot within a few minutes of booting. Also I tried another app, and same result, also ran a full scan of the drive for malware and it came out clean.

If the sensor is on the controller's die, then it will be reporting the controller's temperature. Some SSDs have a separate temperature sensor chip, in which case they report the air temperature . Since your SSD does not have a separate sensor, then it must be reporting the temperature of the controller. Flash controllers normally operate at high temperatures, so your reading is probably accurate.

The drive inside the enclosure appears to be an Adata SU800 (you may be able to see this with CrystalDiskInfo). If so, then searching for SU800 should give you some comparison temperatures.

Make and model of your SSD? Mind also sharing an image of the SSD's partitions(if there are ay) using Disk Manager? Also, FYI, you shouldn't defrag your SSD, regardless of what brand or make and model it is, unless you want to degrade the SSD. You might want to also disconnect the SSD when it's not in use or when not needed since the Windows Defender(Windows 10) will scan through external drives when they're plugged in for added security from malware/threats.

Make and model of your motherboard? Version of Windows 10(assuming you're on Windows 10)?

Its a ADATA SD700... one of those "portable SSDs" that are very compact. My second SSD is half the same size, both in disk capacity and literally size and yet runs at 33 C as I said.
Here is a picture of the partitions from Disk Management: https://ibb.co/cyL4c5C
I keep the SSD connected since I use it for gaming, and yeah I know not to defrag it... is there anyway for windows security to not scan external drives?
And I have an Intel Core i-5 9400 F from ACER... but not sure how that would affect it considering all my other drives are totally fine and its an external drive.
 
That is external SATA SSD. It should not be that hot.
Probably your Asulogics Disk Defrag software is reading temperatures wrong.

Anyway - you can try putting it onto a laptop cooling pad.

Yes I agree it should not be that hot and I did state that it was external on title...
Its potentially a wrong reading, but I tried 2 different apps and got same results, anything else I can try?
Also the touch of my other external (Seagate SSD One Touch) and the touch of my ADATA SSD is totally different, the Seagate feels cold to the touch, while the ADATA feels hot..but not enough to burn me, after unplugging it, it goes to cold as as ice within a few seconds. Could it have something to do with the fact that the ADATA is "Ruggedized Water/Dust/Shock Proof" for the enclosure? I dont think a laptop cooling pad would do anything because of this fact.
 
You can remove it from external enclosure and install internally into your pc.

I am not good at internal installation, hence why I got this external SSD for convenience, I want to rule out everything else before I go ahead and start opening things up....

EDIT: Most likely it seems that whats causing it, is whatever is making the SSD have "activity" as I noticed it when I plug it in, it goes from 40 C to 80 C within a few minutes... and the light that indicates activity stays on for a long time....however Task Manage shows no activity at all.

So I just put an actual fan right infront of it on the highest settings, so strong that the actual physical SSD enclosure now feels cold to that touch... yet im still getting 80 C readings....

Does anyone know what a partial light means on the activity light thing? Its like 1/5 of the full ligth.

EDIT: So I was looking at tech support for another brand of SSD "Transcend"... and it says this on their website "Please note that if you're seeing higher temperature readings with SSD SMART, and if it's a 3D NAND SSD you're using, it is normal and part of the result of elevated performance. Compared to the 2D NAND Flash, 3D NAND comes with LDPC for better error correction, endurance, as well as thermal throttling ability. "

The SSD I have does indeed use 3D NAND... so im wondering if this is true for all SSDs or just that brand, and if its for all of them, how can I get more accurate readings?

Ah thanks for the info!

Btw from the links you provided... it says it should idle at 17-18C and cap at 60 C at most... but this drive is in an enclosure to operate externally and does not have that separate sensor you mentioned, so you are saying this temperatures are totally normal?

I have tried running a virtual LED app that tracks activity like the physical indicator light on the enclosure itself and its showing 0 activity on idle (just to rule out the temps were some activity happening on the background I was not aware of).
 
Enclosures are hotboxes, especially if they are made from plastic. I really can't say whether your high temps are normal. All I can do is to compare them against others.

The fact that it is waterproof means that it is completely sealed, which would then mean that there is no airflow to cool it. I don't know how significant this is when compared with "non-ruggedised" enclosures.

Yeah I can see these rugged enclosure retaining heat unfortunately, I guess not even a fan would help since it would just be cooling the outside of the enclosure only. My other external "non-rugged" SSD is like a third of the physical size and gives me the normal 30 C temps. Sigh... guess there is not much to do at this point, hopefully its just a bad temp reading... I noticed not even the official software from the manufacturer supports this model, so it must be for a reason.
 
There would be nothing stopping Adata from switching to a different SSD inside the enclosure. Could that be the reason for the difference between your observed temperatures and those in the abovementioned review? In fact Adata could even use an NVMe SSD instead of SATA.

You are saying ADATA could put a totally different SSD inside it? Idk if thats a thing...I would think they would make them all standard, would make alot of sense tho if this was true, but idk how to check without opening up the enclosure.
