Summary
Yes (Dynamic Disks, Trim)
Details
(no major updates with WS2019)
Server 2012 has been enhanced to use better just-in-time allocations of storage known as thin provisioning, and the ability to reclaim storage that is no longer needed, known as trim. Hyper-V has been using thinly provisioned disks (Dynamic Disks) for some time, MS typically recommends now to use fixed disks when using the .vhd format (best performance, resiliency) and dynamic disks when using the .vhd format.
Windows Server 2012 identifies and monitors thinly provisioned disks and also provides a new Trim API that allows the underlying physical storage device to reclaim unused space (supported with the new .vhd format). NTFS issues trim notifications when appropriate in real time. In addition, trim notifications are issued as a part of storage consolidation and optimization, which is performed regularly on a scheduled basis. (Trim requires direct-attached storage or SCSI disks and trim-compatible hardware.)
