ESATA

Common card · No. 393493

External SATA (eSATA) is a variant of the Serial ATA (SATA) interface designed for connecting external storage devices to a computer. Standardized in 2004 by the Serial ATA International Organization, eSATA defines connectors and cables electrically distinct from internal SATA in order to make the two physically incompatible and to meet the more demanding requirements of external use. It was widely adopted on desktop computers, laptops, and external hard-drive enclosures during the late 2000s before being largely displaced by USB 3.0 and, later, USB-C and Thunderbolt interfaces. Minimum transmit potential increased: Range is 500–600 mV instead of 400–600 mV. Minimum receive potential decreased: Range is 240–600 mV instead of 325–600 mV. Identical protocol and logical signaling (link/transport-layer and above), allowing native SATA devices to be deployed in external enclosures with minimal modification Maximum cable length of 2 metres (6.6 ft) (USB and FireWire allow longer distances.)...
