I just installed a new NVME SSD (ADATA APSFG-2T-CSUS 2TB) into my laptop (Dell G15 5525 w/ R7 6800H, RTX 3060), replacing the stock one. After reinstalling Windows and installing a few apps, I loaded up CrystalDiskMark to benchmark the disk, but I am seeing some staggeringly low results:
(The sequentials are advertised to be ~7000 MB/s and its an NVME SSD for god's sake)
Usually I would be able to figure out what's going on, but the situation just got more and more confusing.
I reinstalled the stock SSD, ran the benchmark, and got its old speeds (~3000 MB/s sequential, ~30 MB/s random), so I didn't break the M.2 slot with my clumsy fingers or anything.
Next, I put the new SSD into an external M.2 enclosure, connected it via USB, and ran the benchmark. It got exactly 1000 MB/s sequential reads and writes, maxing out the USB connection but still making it FASTER than when it was installed internally ?
I reinstalled the new SSD internally and tried using the laptop normally for a bit, but everything is noticeably slower than the stock SSD (it feels about as fast as my old setup with a SATA SSD which makes sense considering the benchmarks).
Finally, I ran CrystalDiskMark a few more times to make sure, and the weirdest part is that in SOME of the runs, the speeds hit 6000/7000 MB/s just fine???
I have absolutely no clue what's happening, the M.2 slot seems fine and the SSD itself seems fine...sometimes. The laptop specs support PCIe Gen 4 speeds, I have the power plan set to high performance, and the laptop is obviously plugged in.
Is Dell artificially limiting the SSD? Is it thermal throttling?? Is the SSD completely breaking down and having a stroke if I try to push it anywhere past PCIe gen 3 speeds??? Should I have gone Samsung???? How do I get it to run normally?????
It's already 1am and I really need to sleep!!
