Dear member's, I cloned my old 256 GB NVME SSD to a new 2 TB NVME SSD. However, the cloned drive is abysmally slow in read/write speed. Please suggest me what to do without reinstalling the entire system. Here are some results from hdparm:Note:
1: I'm running Debian 12.4 KDE Plasma Desktop
2: Apart from the speed issue, Dolphin takes down the entire system with 100% cpu usage while previewing a big directory with video files. Especially kioslave5 process never stops dropping below 100% cpu usage. Sometimes it takes for ever to generate thumbnails. But this issue is not critical.
Code:
