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.
A read-intensive solid-state drive (SSD) is a NAND flash-based storage or caching device used with applications that write data infrequently, in contrast to SSDs that target write-intensive workloads.
A SAS solid-state drive (SSD) is a NAND flash-based storage or caching device that uses the serial-attached SCSI (SAS) interface to connect to the host computer and fits into the same slot as a hard disk drive (HDD).
A server-based SSD is a solid state drive that may be manufactured in a PCI Express form factor.
