Yes. Drives with the same rotation rates have the same rotational latency. Drives with few platters (higher data density) have higher continuous data transfer rates. (Newer drives tend to use fewer platters.)
As a compromise for the OP, I suggest a 500GB SSD. I don't know about Mexico, but in the US they have become reasonably priced. I stuck one in my Lenovo laptop, and it flies.
