Me and My Dell For Inspiron, G-Series, XPS, and Alienware computers

Internal storage devices are installed on your computer and generally cannot be removed while the computer is turned on. The most common internal storage devices are hard-disk drives—HDDs and solid-state drives—SSDs. HDDs and SSDs use SATA interface to transfer information. SSDs are also physically similar to HDDs, which makes them compatible with existing computers. HDDs contain disk platters. SSDs use flash memory which makes SSDs faster, quieter, energy-efficient, and shock resistant.
