  • 22pin (7pin + 15pin) SATA Combo - The most common type of connector, this can be found in most 5.25", 3.5", 2.5" and a variety of 1.8" drives and hard drives.
  • 29pin SAS Combo - A connecter socket for SAS drives as a SATA combination 22p plug does not fit SAS Drives.
  • 13pin (7pin + 6pin) Slim SATA Combo - This connector type is usually found on Slim Line CD, DVD and Blu-Ray drives.
  • 16pin (7pin + 9pin) Micro SATA Combo - Found on some 1.8 " SATA disks and SSDs.

SAS Connector Type

There are many different type of SAS connector. For compatibility, it is required to check check the SAS connector type of mother board, HBA/RAID controller and back plane.

PCIe v5.0 based Gen-Z and MCIO

In May 2019, the PCIe 5.0 specification was officially released by the PCI-SIG. The transfer speed became twice that of PCIe 4.0 at 32.0 GT/s.

PCIe 5.0 enables new transmission speed of storage via connectors such as Gen-Z, MCIO and SAS are becoming increasingly important.

Connector type Description transmission bandwidth ranges
Gen-Z The mechanism design refers to the specification of SFF-TA-1002.[2] There are four slot directions—straight, right angle, orthogonal, and straddle
  • DESFF E1.S replace M.2
  • DESFF E3 replace U.2
 2.5 GT/s NRZ to 112 GT/s PAM4

MCIO

(Mini Cool Edge IO)

The mechanism design refers to the SFF-TA-1016 specification[3]. MCIO is divided into vertical and right angle. 25 GT/s NRZ to 112 GT/s PAM4
SFF-TA-1016 Specification
