Regarding the last boost, I am not informed enough to know whether the increases in RAM prices are affecting other components, but I can attest to a recent explosion in hard drive prices. I've seen folks blame the AI industry, which I'm sure deserves it, but there are probably several factors at play.<br><br>Years ago, I want to say circa 2017, I started buying 4 Tbyte external USB hard drives because I had access to several low-power NUCs and this was an easy, low-cost way for me to make a resilient, high-capacity storage cluster, one I still use today and am quite happy with. 4 Tbyte was the "elbow" at the time, meaning the lowest dollar-per-terabyte. However, they were also the least expensive: I picked up many of these for $20-$40.<br><br>Today, the same drives are going for $140 at retailers like NewEgg. You can find some for slightly cheaper if you hunt around, and if you're willing to risk refurbished drives you can find them for a bit cheaper still. But from what I can tell you're still looking at $100-ish per drive. That's an increase of 2.5x-7x over the price eight years ago for a component that by conventional logic would have come down in price significantly in that period.<br><br>I guess if I were a filthy capitalist I'd consider selling off my hard drives for a 2.5-7x ROI, but I'm more into use value than exchange value.<br><br>(by the way, this post is not an invitation to critique my hardware choices, suggest alternatives, or compare notes about "home labs").<br><br><a href="/tags/hardware/" rel="tag">#hardware</a> <a href="/tags/tech/" rel="tag">#tech</a> <a href="/tags/prices/" rel="tag">#prices</a> <a href="/tags/ram/" rel="tag">#RAM</a> <a href="/tags/harddrives/" rel="tag">#HardDrives</a> <a href="/tags/storage/" rel="tag">#storage</a> <a href="/tags/ai/" rel="tag">#AI</a> <a href="/tags/aiindustry/" rel="tag">#AIIndustry</a><br>

<p>I overall think the <a href="/tags/opensource/" rel="tag">#OpenSource</a> technology world/sphere is about 70% there in development of systems, that everyone can use with a reasonable amount of effort, but the lapse set is affordability and <a href="/tags/disabilityaccessibility/" rel="tag">#DisabilityAccessibility</a> (mostly for mobility issues). Likewise it's mostly in the <a href="/tags/hardware/" rel="tag">#Hardware</a> not <a href="/tags/software/" rel="tag">#software</a> nor <a href="/tags/os/" rel="tag">#OS</a> spheres, (70/10/20 split) which is why not finding much if any chatter on the Hardware problems is so disheartening, because it needs the most work.</p>
