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.

By how much do SSDs narrow the performance gap between clustered and non clustered indices?

Most SQL relational databases support the concept of a clustered index in a table. A clustered index, usually implemented as a B-tree, represents the actual records in a given table, physically ordered by that index on disk/storage. One advantage…
