Questions tagged [solid-state-drive]

SSD SUPPORT IS OFF-TOPIC. General HDD/SSD support may be asked on Super User (https://superuser.com). A solid-state drive (SSD) is a flash disk similar to a thumb drive, but much faster and with a hard-disk interface, typically SATA.

A solid-state drive is a storage medium based on high-performance flash memory. Most SSD have the same logical interfaces as hard disks (e.g. SATA ). SSDs can be distinguished from HDDs by not having any moving mechanical components.
