I've been experiencing unusually slow download speeds on my second SSD, where I save all my games. Just two days ago, I noticed that my game downloads were notably slower, and textures are taking longer to load. I have two SSDs— the first one, which only has 120GB for Windows, downloads at normal speeds. However, my second SSD, with 500GB capacity, is behaving sluggishly. I've ensured everything is up to date, including Windows, BIOS, and drivers. Both SSDs are healthy and have good temperatures according to scans, but it's puzzling because my first SSD has a lower lifespan (33%) than the one that's slow (77%). I'm at a loss for what to do next. Can anyone help?

Is your slow SSD nearly full? Sometimes, SSDs can slow down significantly when they're close to being full.
It sounds like a good idea to run a speed test using CrystalDiskMark to check the read and write speeds of your second SSD. Just a quick note: make sure not to overdo it with the testing, as it can wear out the SSD. Try a sample size of 500GB, but only test the first row to see if you're getting over 80 MB/s on the transfer.
I actually found that CrystalDiskMark doesn’t start well on my sluggish SSD either, but the health check from CrystalDiskInfo reported that both are fine. So it seems like there might be another issue at play.
What brand and model are your SSDs? Many of the budget SSDs are DRAM-less and use slower QLC flash, which can lead to performance issues over time. It could just be that your second SSD isn't built for high performance.
It's a Kingston SSD, and I've had it for about four years since I built my PC.

Nope, it still has plenty of space—around 190GB free, so that shouldn't be the issue.
