    External mSata ssd very hot.

    Having tried HWiNFO64 to get temperature of external drive. = 53/54 Celsius
    Kingston mSata SUV500MS 480GB in aluminium enclosure via short cable to USB C/Thunderbolt socket.
    Machine uses AHCI.
    Task Manager shows ssd at gentle use but is nearly too hot to keep hand on casing.
    After some minutes ... C: drive at zero, CPU at 3 percent or less, mSata ssd at zero percent, memory at 22 percent .... still very hot.
    Aluminium enclosure is in free air resting on an acrylic flat surface (part of a stand to improve laptop ventilation).

    Now after more minutes at idle ... max temperature up to 55. Shows activity in all areas of zero.
    Internal C: drive nvme = 29 max.
    Chipset max = 40.

    Is this mSata ssd drive going to have a very short life ?

    My primary SSD (Samsung 950 Pro 512GB NVMe SSD) runs at 53C all the time. Never had a problem with it, Been running it that way for 2+ years without issue. Amusingly my external drives are all between 28 and 32 C (don't have temp sensors on some of my other internal drives for some odd reason, but my spinners are all between 31 and 31 C internally as well). M.2 drives tend to run warmer: looks like that's a pretty common temp range on my laptops, too.

    As I understand it, this is not a (PCIe) NVMe SSD, but a SATA one, with an mSATA connector, not an M.2 connector. I think it should run at a lower temp. Maybe a problem somewhere in the USB link. If possible, I would connect it to a USB-A port, to compare.

    Thank you "EdTittel" and "Anibor"
    Yes this is an external mSata not M2. And is 2242 size.
    Testing now from cold overnight with these results ..
    CPU core=29
    NVME = 22
    mSata = 22 (this time into usb A)
    A spare Toshiba 500gb spinner on usb A = 17

    Watched the mSata temp climb instantly ...
    Zero activity first few minutes and then some very light web browsing.

    25 minutes in and these result..
    CPU = 38
    NVME = 24
    mSata = 43
    hdd = 25

    Then copy paste 4GB jpegs from mSata to hdd
    CPU = 40 (drops to 37 after paste)
    NVME = 22
    mSata = 45
    hdd = 26

    Next test will be with an M2 on an open adaptor plate ... and thinking of just using microSD as storage but cannot find the temp for that even when hwinfo64 restarted.
    Actually seeing the problems with electrical circuits condensed to small sizes ... the limits of computing and the brick wall for Moores law perhaps.
    Dont think water cooling for laptops is going to make my fortune !

    M2 128GB 2242 formfactor into usb A.
    hwinfo did not see any temperature for this at first... but started testing.
    Deleted oer 100GB fro M2, quick format and then pasted 180GB.
    All this from the mSata in the usb C port as donor for temperature comparison.
    Still running but very clear temp difference.
    MSata in Alu casing is getting hotter while M2 on open card is still luke warm to the touch.
    NVME = 37
    M2 = 35 / 36
    mSata = 47 / 48

    Even after a few minutes it is clear the M2 is running cooler.
    Anyone want a toasty/toasted mSata?

    "Is this mSata ssd drive going to have a very short life ?"

    No, because the temperatures are taken in to account in the SSD design.
    There is nothing wrong with those internal temperatures.

    The power dissipated in an SSD has a very small source so it gets hot, the memory cell chips.
    The casing of your external drive is essentially the heatsink to the very compact solid state devices inside.
    In a sense the aluminium casing is too small and inadequate it should have much better heat dissipating qualities, but that would not be attractive to consumers whose expectation is a very small external SSD drive.

    A desktop HDD is much chunkier and the storage method is very different. The power is used mainly to spin up the drive platters and to keep up the revs. The control electronics power is a lot less.
    In a Desktop PC HDDs are usually in the airflow thru the case, a much better heat removal scenario.

    Then there is the placing and calibration of the temperatures sensors themselves...another ball game.

    Made a choice

    Going with a new Samsung 860 Evo after looking at the power consumption comparisons on L1.2 state and when in operation.
    Better fuel consumption, less to waste as heat. Used for daily storage so not interested in speed, just dont want any more spinning discs in this context Still use them for backups though..
    But still reading that magnetic spinners have a much longer life and have years of proven mass reliability whereas even the flash proponents expect/assume charge based storage will fade over time and not be as long lived.

    As some of my files (images of historical paper documents) have been on various drives for over 20 years I am using belt and braces and have copies of backups and vice-versa on spinners and flash.
    Just wanted something less fragile and more portable for use in various places and between two machines where network is not an option.

    So thank you for opinions and suggestions.
    Over and out.
