In theory yes. But it is unlikely. The files are very likely balanced before you delete them so it should be mostly balanced after. It will also self-correct the difference after a bit more use. Unbalanced drives can affect performance as one drive will have to do more of the work often bottlenecking. But except for extreme cases it is probably a rounding error.
