Hard Disk Unexpectedly Not Dead
As I read Zak Killian's Expect HDD, SSD shortages as AI rewrites the rules of storage hierarchy — multiple companies announce price hikes, too I realized I had forgotten to write this year's version of my annual post on the Library of Congress' Desihning Storage Architectures meeting, which was back in March. So below the fold I discuss a few of the DSA talks, Killian's more recent post, and yet another development in DNA storage. The TL;DR is that the long-predicted death of hard disks is continuing to fail to materialize, and so is the equally long-predicted death of tape.
