Hi,
Copying 15GB of files – as an example – (few and large not many and small) from my C drive which is on a sata adata 128GB ssd (rated at 500MB/s reads) to my G drive with is on an intel nvme pcie ssd rated at 1800/1800 R/W is unbeliveably slow. bursts at 200MB/s settles at 47MB/s … I’m at a loss for words.
The drives are new. they perform as expected under crystaldiskmark/atto benchmarks.
My pc specs : windows 10 64bit, ryzen 7 2700x, rtx 2080, asrock x470 taichi, all updates, latest drivers etc. i assembled the rig myself, installed the os everything myself. did not expect this at all.
Source SSD: Adata SP900 128Gb sata3 ssd
Destionation SSD: Intel ntel 660p NVMe PCIe M.2 1TB
Motherboard has latest bios from asrock page.
I did not do anything io intensive in the background, the system is not malware infected, i keep things nice and tidy both hardware and software wise.
What in the world is going on ?
