    Defragmenting virtual drive wthin virtual machine running on SSD?

    I use VMWare (V12 Pro) to test OS's and other software. From time to time, when I close a guest OS, VMWare advises me to defragment my (virtual) drive. I am running VMWare on an SSD under Windows 10 Pro. Is defragmentation actually necessary? If the guest OS is Windows 10, surely it is trimming the virtual drive it is installed on in the same way that the host Windows 10 trims its drive? I cannot find any VMWare support pages or forum posts that address the issue of SSDs in this scenario. Any opinions/advice?
    (My Setup: Custom built: 4.00GHz Intel Core i7-6700K CPU; MSI Z170A Gaming Carbon Mobo (Military Class V); Win 10 Pro (64 bit)-(UEFI-booted); 16GB RAM; 500GB SAMSUNG 960 EVO M.2 NVME SSD; 512GB SAMSUNG 850 PRO SSD; Seagate 2TB Barracuda SATA6G HDD; 2 X GeForceGTX 1070 8GB Graphics Card (SLI); Office 2016 Prof "Click to Run" (32-bit); Acronis TI 2017 Premium, Norton Internet Security, VMWare Workstation12 Pro).

    Just because you don't know where you are going doesn't mean any road will get you there.

    SSD's normally don't need to be defragmented. Can't see why running a virtual disk on one would change that.

    VMWare won't be aware you are using a SSD, so that should be seen as just standard advice. Let Windows deal with the disk defragmentation and don't worry about it.
