The darker rice contains more oil. Oil goes bad faster.
I don’t keep more than 5 lb at a time of brown rice, but I keep it in the freezer. Ditto for red rice and black rice. FYI red rice is the Power House of nutrition in the rice family.
I have white rice stored in half gallon tanning jars with desiccant pouches. It will last much longer than it will take us to eat it.Jasmine rice running Thailand is generally lower and arsenic than most rices. Ditto for imported basmati.
