It's not so much batch these days as conditions. Individual sellers probably use the same shipping method for every order and they may order in large batches which are transported at the same time. Although SSDs are a bit more resilient, hard temperature spikes in a single batch won't be detected after shipping. In the past, we would do this for hard drives because although parked heads are safe, high G-loads could actually unpark a head.
