Internal Drive Connectors
For many years, desktop computers have utilized the IDC 40 connector as an internal interface for hard drives. The IDC 40, commonly
found on motherboards, allows up to two devices to be connected using a single cable. Applications requiring the connection of
more than two devices require a connection through a separate IDC 40 on the motherboard, or the installation of an additional host
controller card. With the advancement in portable technology the IDC 44 connector was developed for use in laptop computers.
Although physically smaller then an IDC 40, the IDC 44 possesses additional pins to supply power to a 2.5in hard drive, eliminating
the need for a cable. In addition, the IDC 44 provides a swappable interface for easy installation and removal. With the demand for
a faster interface, these IDC connections are being replaced by SATA technology found in new computers today. Older IDC devices
can be used with the newer SATA interface using a serial ATA converter board adapter. Applications requiring the connection of
multiple drives can benefit from the use of SCSI technology.
SCSI is a bus technology which allows devices to be chained together reducing the number of cables connected directly to the
computer. In an internal SCSI application, multiple devices can be connected through a single cable reducing congestion and
increasing air flow. Most internal SCSI applications utilize an MD50 or MD68 connection which closely resembles a larger IDC 40
connection. Although the parallel SCSI technology is being replaced by the new SAS (Serial Attached SCSI) technology, parallel SCSI
is still used today in education, government and some end user applications.
