because 1EB is a minuscule amount of the hard drive capacity, compared to the total amount produced per year. According to seagate's blogpost[1], they ship at least 500 EB per year. If you add in capacity from WD/toshiba, it's probably closer to 1000EB if not more. That would make chia's consumption 0.1% of produced hard drive capacity.

Very much agree here. I purchased about 144TB of raw storage a few weeks ago for future video and data projects, and it's possible to purchase 1PB of raw capacity (with no redundancy, nor anything to connect to) for as cheap as around $13000 USD at retail pricing.
1EB could be acquired for somewhere between $12-$15M. Not chump change, but considering the number of players pre-mining, absolutely nothing in the scheme of things.

What will be interesting is how this increase in mainnet capacity grows over time, and relative to manufactured capacity. 1.1EB of footprint today is nothing ... but we might start to care if it were to grow at a rate of 1.1EB/day or faster, as manufacturers like Seagate, WD, Toshiba, etc. can't instantly respond to such a sustained demand spike. Channel supply could be exhausted relatively quickly.
HDDs have been hit much harder than SSDs, but I’m guessing you didn’t buy 144 TB of SSDs.
High-speed DDR4 ECC memory (DDR-3200 in particular) can also be tough to come by. A fair number of VARs actually limit quantity (usually to 20 modules per SKU), since it's so tough to get. Again, not due to crypto mining, but because of hyperscalers.
2. Started with around 120 PByte. Seven weeks later and it'll be already a decimal order of magnitude bigger.
0.1 percent isn't minuscule.
Part of the reason for this is because Chia is really easy to farm — anyone with extra space on their hard drives can do it. There are people farming a petabyte with a Raspberry Pi. This was by design to keep the network decentralized and hard to attack — close to the original intention of "one cpu one vote" from bitcoin.
Right now there's no price for Chia since it's not on exchanges and transactions won't start until May 3. But in the short term it's advantageous to buy enterprise-level SSDs because they're the fastest to "plot" with so it seems that in a few markets, especially in China where interest in farming Chia is surging, a few SSD sellers have seen a spike in demand.
For long-term effects on the storage industry it's hard to say what will happen — there's tons of existing storage out in the world already, the storage industry already sells 1+ zettabytes of storage a year, and unlike single-use bitcoin mining hardware hard drives are useful outside of Chia. The Chia company speculates on the impact on the storage industry on page 23 of their business whitepaper: https://www.chia.net/assets/Chia-Business-Whitepaper-2021-02...
