Why each option
WORM (Write Once, Read Many) devices allow data to be written only once and then read multiple times, with CD-ROMs and DVD-ROMs being classic examples.
SAS (Serial Attached SCSI) is an interface standard for connecting storage devices like HDDs and SSDs, which are typically re-writable, not WORM.
A CD-ROM (Compact Disc-Read Only Memory) is designed so that data is written to it once during manufacturing or recording, and thereafter can only be read multiple times.
An SSD (Solid State Drive) is a type of non-volatile storage device that allows data to be written, erased, and rewritten multiple times, making it not a WORM device.
A DVD-ROM (Digital Versatile Disc-Read Only Memory) functions as a WORM device, where content is permanently stored once and can be accessed for reading an indefinite number of times.
SCSI (Small Computer System Interface) is an interface for connecting and transferring data with peripheral devices; it is not a WORM storage device itself.
