I have Samsung as well as Adata SSDs. On Adata sometimes when I copy a very large single file say 4 GB file, it starts with say 190MB/s but during copy as it proceeds speed suddenly drops to as low as 15 MB/s then fluctuates a lot but many a times it stays at 15 - 20 or sometimes goes back to 180 – 190MB/s again varies.
It feels as if it’s copying data to a pen drive rather than SSD.
I have run sstoolbox app and it reports good status as well as smart is also fine. It says firmware is latest. What causes so much drop in write speed on SSD? What I have is Su630 and to my knowledge it does not have dram.
I never faced this issue with Samsung one.
Yet when I run speed test on adata it shows > 400 MB/ Read as well as Write speeds!
So speed test appears deceptive to me.
On paper there's nothing wrong with this SSD!! So I am clueless. Any help is much appreciated.
