Not economical. Storage is already done on far larger fab nodes than CPUs and other components. This is a case where higher density actually can be cheaper. ”Mature” nodes are most likely cheaper than the ”ancient” process nodes simply due to age and efficiency. (See also the disaster in the auto industry during covid. Car makers stopped ordering parts made on ancient process nodes, so the nodes were shut down permanently due to cost. After covid, fun times for automakers that had to modernise.)
Go compare prices, new NVMe M.2 will most likely be cheaper than SATA 2.5” per TB. The extra plastic shell, extra shipping volume and SATA-controller is that difference. 3.5” would make it even worse. In the datacenter, we are moving towards ”rulers” with 61TB available now, probably 120TB soon. Now, these are expensive, but the cost per TB is actually not that horrible when compared to consumer drives.
