Why are 1.92/3.84/7.68TB hard drives the standard?

For SSD drive, I often see specifications like 200GB, 400GB, 800GB, 1.6TB, 1.92TB, 3.84TB, 7.68TB (For example, HPE 7.68TB SATA 6G Read Intensive SFF SC Multi Vendor SSD)

Is there a hardware/architectural reason that makes it go from 1.6TB to 1.92TB, instead of having 3.2/6.4TB hard drives?

An SSD requires Flash chips for storing the data. There are 4 manufacturers for flash chips and the capacity on their chips determines what SSDs can be built. Furthermore SSDs I know only contain one type of flash chips. The rest is simple math.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
