Alright random folks, my computer runs on an I5 2500 with a non-K 3.5" HDD spinning at 5500 RPM, a Hitachi 2.5" HDD at 7200 RPM, and 4GB DDR3 RAM (planning to upgrade to 8). It comes with an RX 570 8GB from Gigabyte. The operating system is installed on the 3.5" drive, but performance feels sluggish rather than laggy—just a bit slow. I track my usage via Task Manager during regular tasks, and both RAM and CPU aren’t fully utilized. There are no noticeable utilities indicating a bottleneck. My idle RAM sits around 1.8–2GB. It seems the hard drive is likely the main limiting factor, but I want to confirm before making any changes. I remember my previous laptop had an I5 6300U and was noticeably faster on the 2.5" drive, with fewer pauses and quicker loads. That experience makes me cautious about swapping drives now.
Standard use? Speed of loading? Time to install? Switch to an SSD. Even upgrading to a SATA SSD feels like ascending to paradise.
The SSD used for the operating system was the initial improvement, making a huge impact. However, other upgrades are catching up quickly. Today's 4GB RAM won't function properly, leading to excessive swapping, which is even worse on an HDD... quite problematic. A 2.5" hard drive probably won't be faster, just because it avoids handling the OS and swapping along with the main tasks.
I thought about it and it finally clicked. Absolutely, 4GB won't work anymore. It's been days since then, and it's barely running at all—around 50-60 frames per second now. After that, it slows down to about 10 seconds and then freezes for a couple of seconds.
Purchase an SSD with a maximum speed of 500 MB/s, blue color, and Samsung Evo 860/870 EVO. Find it on eBay for around 15 dollars. Avoid ECC models.
Windows 10 (and 11) runs sluggishly on hard drives; the last version that performed well on HDDs was Windows 8.1, and even then the gap between SSD and HDD remained significant. With only 4GB of RAM, the operating system struggles to cache data, forcing it to rely on the page file on the slower HDD. An SSD is essential for contemporary operating systems, just as 8GB of RAM is necessary. For newer PCs, at least 16GB is recommended. Although the i5-2500 is now 13 years old, it should still handle everyday tasks smoothly. Of course, it won’t match the speed of much newer processors.
I'm using a lot from just an old Samsung external 2.5 drive—it's fine, really. I don't really feel any difference. Sometimes I'm surprised by how fast and smooth everything runs. My last game was on bright memory (ahem), and I'm not sure if it's a tough one, but it definitely looks pretty janky. Still, it runs super smoothly thanks to the external HDD. That said, I agree with the point: nothing OP could really improve performance on such an old system more than having at least a decent SSD running the OS! This makes a big difference, especially on older machines.
