Seagate said in May 2021 that the company was experiencing strong orders and that staff were working to "adjust to market demand".
In May 2021 Gene Hoffman, then president and current CEO of Chia Network, admitted that "we’ve kind of destroyed the short-term supply chain" for hard disks. During the first months since Chia's launch, concerns were raised about the prerequisite plotting process drastically limiting a hard drive's lifetime.. In late 2024 and early 2025, reports emerged of used hard drives being fraudulently resold as new, with Chia farms being identified as a likely source. These farms were reportedly closed because Chia mining was no longer profitable.
