Windows 10: Make Windows 10 realize USB 3.0 connected drive is an SSD, not an HDD.

    Make Windows 10 realize USB 3.0 connected drive is an SSD, not an HDD.


    I have an SSD inside an Inateck FE2006 case, and Windows recognizes it fine. *But* when I look under drive optimization, it says it's an HDD and not an SSD (and will thereby try to defragment it instead of sending TRIM commands). Now, when I run CrystalDiskInfo, it realizes that it is an SSD, which one, that it supports TRIM, etc. - just like if it was connected via SATA 3. So the USB 3.0 to SATA 3 controller doesn't seem to generally block these things.

    Now I'm wondering, is there a way to make Windows 10 [Version 10.0.14393] realize that it's talking to an SSD and not to a hard drive/make it send TRIM commands to it?

    Something you could try:

    Plug in your ext. SSD, open a command prompt and try the following where # is the drive number you see in disk management.
    Then reboot your system, and see if Windows sees the disk as an SSD, because it now knows how fast it is.

    Code:
    winsat disk -n #
    Example:

    Well, I tried it (including restart), but that didn't do anything unfortunately.

    Code:
    winsat disk -n 4

    Sorry that's all I could think of.
    Maybe someone else has an idea.
    WINSAT is so the system learns what the capabilities of your system hardware are, and then usually makes settings in the OS, according to the scores. I always run it after driver upgrades, or when I install new parts.

    Hi,

    I have an SSD inside an Inateck FE2006 case
    If that case uses UAS protocol then that would explain why it doesn't support TRIM and hence treat your drive as if it were a HDD.

    While you CAN defrag a SSD like you would a HDD, you really shouldn't as it just doesn't need it because latency is so low you'd hardly notice a difference.

    To find out if the case supports UAS open device manager and check for an UAS entry under Storage controllers.

    Uhh... you're confusing me a bit. I'm pretty sure UASP supports both UNMAP and direct ATA command passthrough, which could both be used to support TRIM? I mean, as far as I know UASP was pretty much made to do this. Did you mean to ask if it is not using UASP?

    Hi,

    Did you mean to ask if it is not using UASP?
    No, I would like to know if it supports UASP for that would explain what you are experiencing.

    Checked it and yes it does use UAS which does not support TRIM so Windows looks at it as if it were a HDD as far as optimization is concerned.
    Other then that it should be faster than a USB 3.0 connection though.

    What makes you think UASP doesn't support TRIM? UASP supports TRIM fine via two different methods, like I wrote above... and as I wrote in my entry post, CrystalDiskInfo is able to detect that just fine.

    It does not support it natively, hence the use of the UNMAP hardware command which not all UASP hardware supports.
    Windows however will treat your drive as if it were a HDD when you want to optimize it.

    Now I'm wondering, is there a way to make Windows 10 [Version 10.0.14393] realize that it's talking to an SSD and not to a hard drive/make it send TRIM commands to it?
    Short answer: No.
    The main reason being that SCSI devices are unaware of trim command so these need to be translated.

    You can TRIM it manually using the /L switch while using the defrag command
    Code:
    defrag X: /L /U /V
    Where X: is the partition letter
    /L Perform retrim on the specified volumes. Only for a SSD.
    /U Print the progress of the operation on the screen.
    /V Print verbose output containing the fragmentation statistics.
