Other FactorsThere are currently four different bus types for transferring data to and from the memory itself, UHS-I, UHS-II, UHS-II, and Express. While UHS-II and UHS-III share a contact layout, UHS-I uses only the top row of pins, and Express substitutes the lower row found on UHS-II and UHS-III for its own. As a result, the cards are technically backwards compatible with slower devices, but Express cards will only run at UHS-I speeds in devices without Express support, due to the Express pins not lining up correctly with the UHS-II pins. You'll find that most modern cards UHS-II, as it has more than enough speed to support V90 cards.
The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.，详情可参考体育直播
