I've been curious about the actual performance differences between SSD speeds, especially comparing Gen 4 and Gen 5 models. Specifically, in what scenarios do the increased speeds and lower latency of a faster SSD actually translate to noticeable performance improvements? For example, I've heard that Gen 4 SSDs are generally sufficient for gaming—so is upgrading to a Gen 5 really necessary? How do things change for tasks like AI work with local LLMs, or 3D workloads in programs like Blender and Unreal Engine? Lastly, should I prioritize upgrading to a better SSD, or focus on improving my CPU and RAM first for a more noticeable performance boost?

If you’re into more demanding tasks like video editing or 3D modeling, then that's where a faster SSD becomes important. Having a separate SSD for those tasks can help a lot. For instance, using a fast NVMe for your video editing projects can really speed things up. Plus, if you plan on doing serious work with Unreal Engine or Blender, remember that having enough VRAM on your GPU is just as crucial as SSD speeds!
The speed of an SSD really shines in heavy tasks like video editing or working with large files. If you're doing video editing, you'll want a high-performance SSD. For general use, TLC NAND drives are much better than QLC ones, especially when their SLC cache runs out. I’d definitely recommend something like the Samsung 970 Evo (TLC, Gen 3) over any newer QLC models, as you’ll get much better sustained speeds.
Upgrading from an HDD to an SSD is a game changer! If you're coming from an HDD, any SSD will give you a significant performance boost. For a solid experience, aim for an NVMe Gen 3 at minimum for your operating system and frequently used apps—Gen 4 is great, but even SATA SSDs can do the job for gaming. They're more than capable!
Yeah, I've seen people get by just fine with SATA SSDs. They're a solid choice for OS drives without breaking the bank.
Honestly, for gaming, a Gen 5 SSD won't offer much of a difference. Only a handful of games can take full advantage of those speeds, and even then, you may not see a drastic change. Plus, technologies like DirectStorage are still slow to be adopted in games, so unless you're a power user, it probably won’t make a noticeable difference in your gaming experience.
Exactly! A lot of gamers wouldn't notice if you swapped a Gen 5 for a Gen 3 SSD. It's not like there's a huge gap in performance right now.
For most everyday users who already have an SSD, upgrading further often won’t provide that much benefit. Unless you're doing heavy workloads or gaming at the cutting edge, it might be better to focus on getting a better CPU or more RAM for improved performance overall.

Totally! The Crucial P3 Plus isn’t the best anymore either—it's just better than older QLC models. But yeah, TLC drives win for reliability and speed!
