Yetersiz NVME SSD Performansı (sadece Linux'ta)

[Empat]

Dual boot olarak Windows ve Ubuntu kullanıyorum. Adata s40g NVME SSD 3500/1200 NVME m2 SSD'ye sahibim. Bu SSD, Windows işletim sistemimde 2200/1200 ve Linux işletim sistemimde 1000/400 hızlarında performans gösteriyor. wiki.debian.org adresinde önerilen SSD optimizasyonlarını denedim.

Fio aracıyla yaptığım testte sonuçlar harika. Gnome Disks ve hdparm araçları ile yaptığım testte sonuçlar berbat. PhpStorm gibi bir yazılım açarken, fio ile test ettiğim hızı hissetmiyorum.

Ne yapmalıyım? Yapmam gereken optimizasyonlar nelerdir?

[burakerkus]

[mention=650690]@Empat[/mention] Hocam başka forum da yetersiz performans aldığı söylenmiş fakat nasıl çözüm bulduğunu anlayamadım o yüzden link atıyorum.

https://bbs.archlinux.org/viewtopic.php?id=180937&p=2

burada da perforans düşüklüğünün test koşullanrından dolayı olabileceği söylenmiş.
