For several years, I posted a note here called "Terabyte Update" in which I compared the cost of various types of storage. The primary purpose was to track the rise of solid-state storage drives (SSDs) compared to traditional hard disk drives (HDDs). The last issuance of my guidance was in 2018.

But I haven't been silent on the matter. I've been the editor of the AskWoody newsletter since 2021, where Terabyte Update continued to appear. Here's the entire history.

• Terabyte Update for 2025 ($), 2024 ($), 2023, 2022, 2021, and 2020 at AskWoody
• Earlier editions at fastie.com for 2018, 2011, and 2009

The articles at AskWoody marked with a dollar sign are, regrettably, behind the paywall. The good news is that subscribing to the newsletter is a bargain!
