Moin!
Ich hab hier ein gewaltiges Problem.
Es ist eine mSATA-SSD und eine normale HDD eingebaut.
Bei beiden Geräten hab ich im schnitt 500KB/s-1MB/s etwa an Lese- und Schreibgeschwindigkeit..
Jemand eine Idee, wie man das debuggen könnte? Offensentlich kann es nicht an der SSD/HDD direkt liegen, wenn beide in etwa gleich lahm sind.. vorallem ist auf der HDD gerade mal nur paar GB drauf..
