  In the last decade, high-resolution X-ray spectroscopy has revolutionized our
understanding of the role of accretion disk winds in black hole X-ray binaries.
Here I present a brief review of the state of wind studies in black hole X-ray
binaries, focusing on recent arguments that disk winds are not only extremely
massive, but also highly variable. I show how new and archival observations at
high timing and spectral resolution continue to highlight the intricate links
between the inner accretion flow, relativistic jets, and accretion disk winds.
Finally, I discuss methods to infer the driving mechanisms of observed disk
winds and their implications for connections between mass accretion and
ejection processes.
