This Hacker News discussion centers around a detailed test of DVD±RW disc rewrite endurance ([https://goughlui.com/2024/07/28/tested-how-many-times-can-a-dvd-rw-be-rewritten/](https://goughlui.com/2024/07/28/tested-how-many-times-can-a-dvd-rw-be-rewritten/)). The author’s extensive testing revealed DVDs can withstand *far* more rewrites than commonly believed – thousands, even – challenging the perception of limited lifespan. Many commenters shared nostalgic experiences with DVD-RWs, recalling their use before widespread flash drive adoption. A key takeaway is that media quality matters, and faster burn speeds can reduce reliability. Several users pointed out that while rewritable DVDs were available, their perceived unreliability led many to stick with write-once discs. The conversation also branched into discussions about alternative archival storage solutions like LTO tape (expensive but high capacity) and SSDs, with considerations for data retention and wear leveling. Some lamented the loss of technologies like Intel Optane, offering superior performance. Ultimately, the post sparked a fascinating look back at a once-common technology and its surprisingly robust capabilities.
