Samsung 980 SSD disk slow download

[iFluffy]

Heyo my friend bought Samsung 980 SSD disk 1 TB, M.2, PCI-e 3.0 x 4 NVMe and tried using it today. While he was downloading GTA 5, it went from 160 Mbps to 23 average.

Is this because it Dramless ssd?

Dram shouldn't affect downloads, loading games and stuff maybe, but not downloads.

Try using CrystalDiskMark and run a Speed test for it whilst not downloading.

EDIT: Illusion is write I had that part backwards

Thanks will try. I will get more updates tomorrow, he is using b550 A pro motherboard.

That's actually backwards.

DRAM effects writes, not reads, so loading games will be no different whether DRAM is present or not.

Installing games (which is being done while Steam downloads), however, is writing to the drive. That may be impacted by a lack of DRAM, but the drive's cache and NAND write speed are going the be the real factors that determine performance for that. It just so happens that drives without DRAM also tend to have slower, smaller caches and/or slower NAND.

Whatever differences the lack of DRAM causes will be minimized further on NVMe drives where HMB uses system RAM to substitutes DRAM. On SATA, yeah, a bit of a different story.

If an SSD drive ever slows from one consistent speed to another during a long writing task, it is likely because the cache has been exhausted and its writing to slower NAND.

And remember those files need to be decompressed too, slows writes a bit.

Update, while he was downloading steam games he still had lots of windows updates. After it got updated his speed went up to 500 Mbps.

Thanks anyway, for future stuff
