Wǒ huàn le yī kuài gùtài yìngpán, diànnǎo kuài duō le.
I swapped in an SSD (solid-state drive), and the computer is much faster.
Tips
usage
固态硬盘 gùtài yìngpán = SSD; 固态电池 gùtài diànchí = solid-state battery. Pairs systematically with 液态 yètài (liquid state) and 气态 qìtài (gaseous state) — these three 态 forms are the standard middle-school physics trio.
