Bidirectional
Tus nqi qis
Tuaj yeem siv nrog slurries thiab viscous kua
Muaj nyob rau hauv loj loj
Inherently Hluav Taws-nyab xeeb (thaum siv nrog daim ntawv hlau)
Qhov tsis zoo yog:
Maj qhib qhib thiab kaw lub sijhawm
Tsawg-siab txwv
Yaig ntawm lub rooj zaum thiab disk tuaj yeem tshwm sim
Phem throttling yam ntxwv
Nyuaj kho
