2. Dual-ported RAM - Wikipedia

   en.wikipedia.org/wiki/Dual-ported_RAM

   Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...

   Two 2.5" external USB hard drives Seagate Hard Drive with a controller board to convert SATA to USB, FireWire, and eSATA Current external hard disk drives typically connect via USB-C; earlier models use USB-B (sometimes with using of a pair of ports for better bandwidth) or (rarely) eSATA connection. Variants using USB 2.0 interface generally ...

4. Random-access memory - Wikipedia

   en.wikipedia.org/wiki/Random-access_memory

   Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk. The RAM disk is reloaded ...

5. Hybrid drive - Wikipedia

   en.wikipedia.org/wiki/Hybrid_drive

   A hybrid drive (solid state hybrid drive – SSHD, and dual-storage drive) is a logical or physical computer storage device that combines a faster storage medium such as solid-state drive (SSD) with a higher-capacity hard disk drive (HDD). The intent is adding some of the speed of SSDs to the cost-effective storage capacity of traditional HDDs.

   Initially all external storage, tape and hard disk drives are today available as both internal and external storage. In the 1964 removable disk media was introduced by the IBM 2310 disk drive with its 2315 cartridge used in IBM 1800 and IBM 1130 computers. [7] Magnetic disk media is today not removable; however disk devices and media such as ...
