Honestly looks highly suspicious to me. Because ok they might need some big storage like petabits. But how can this be a match in proportion with the capacity that is currently usually needed for everything that is hard drive hungry. Any cloud service, any storage service, all the storage needed for private photo/video/media storage for everything that is produced everyday, for all consumer hardwares like computers...

Gpu I understand but hard drive looks excessive. It's like if tomorrow there is a shortage of computer cabling because ai datacenter needs some.

If you're building for future training needs and not just present, it makes more sense. Scaling laws say the more data you have, the smarter and more knowledgeable your AI model gets in the end. So that extra storage can be quite valuable.
