A 3.5 solid-state drive (SSD) is a data storage device designed for the 3.5-inch hard disk drive (HDD) form factor. It fits into the drive slot as a same-sized HDD in a portable computer, enterprise server, or storage system.
HDD form factor is the size or geometry of a hard disk drive, determining the device’s compatibility with the drive bays in a storage array or enclosure, server, portable computer or other computing device.
An mSATA SSD is a small-form-factor solid-state drive designed for portable devices such as laptops and tablets. Advantages include low power and vibration resistance.
An NVDIMM (non-volatile dual in-line memory module) is hybrid computer memory that retains data during a service outage.
