Examples include techniques for managing high priority (HP) and low priority (LP) write transaction requests by a storage device. An embodiment includes receiving, at a storage controller for a storage device, a write transaction request from a requestor to write data to one or more memory devices in the storage device. When the write transaction request is for a high priority (HP) write, coalescing the write data into a transaction buffer in a memory of the storage device, sending an acknowledgment for the write transaction request to the requestor, and writing the write data into the one or more memory devices. When the write transaction request is for a low priority (LP) write, writing the write data into the one or more memory devices, and then sending an acknowledgment for the write transaction request to the requestor.
