2. SATA - Wikipedia

   en.wikipedia.org/wiki/SATA

   A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...

3. Hard disk drive interface - Wikipedia

   en.wikipedia.org/wiki/Hard_disk_drive_interface

   Power cable not shown. The earliest hard disk drive (HDD) interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data. [a] An additional cable was used for power, initially frequently AC but later usually connected directly to a DC power supply unit. The controller provided ...

4. SATA Express - Wikipedia

   en.wikipedia.org/wiki/SATA_Express

   The connector on the host side accepts either one PCI Express SSD or up to two legacy SATA devices, by providing either PCI Express lanes or SATA 3.0 ports depending on the type of connected storage device. [13] There are five types of SATA Express connectors, differing by their position and purpose: [2]

5. Parallel ATA - Wikipedia

   en.wikipedia.org/wiki/Parallel_ATA

   There are many debates about how much a slow device can impact the performance of a faster device on the same cable. On early ATA host adapters, both devices' data transfers can be constrained to the speed of the slower device, if two devices of different speed capabilities are on the same cable.

6. Port multiplier - Wikipedia

   en.wikipedia.org/wiki/Port_multiplier

   While the controller is aware that there are multiple drives connected, the service is transparent to the disks attached. Because they believe they are communicating directly with the controller, any drive that holds to the SATA standard can be connected to a port multiplier. There are two ways port multipliers can be driven:

7. List of interface bit rates - Wikipedia

   en.wikipedia.org/wiki/List_of_interface_bit_rates

   Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.
