I'm not intimately familiar with the various players in the storage market, but as an outsider I would guess that Western Digital must be doing alright. They could have, but didn't, break up the price-fixing ruling that market and taken it over handily if need be. Amazing that in 2018 it's still more expensive to get data storage on a dumb grid of NAND gates built out of common materials than it is to get it on hard drives infused with helium, sporting a high precision high speed motor, platters coated with rare materials, neodymium magnets, and, coming soon, lasers!
