Happens all the time when you buy storage in batches. We learned a lesson, go through 3-4 suppliers and split your orders over a three month period. Buying from one place in bulk is just guaranteeing data loss in your future.
I've dealt with deployed systems that had (in many different clusters) a total of upwards of 100K HDDs and also with 10K SSDs and for extended periods.
I saw tons of drive failures of many types but never even once did I see two or more drives of the same batch fail soon one after the other.
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.
