CABLES

ATA / PATA / ATAPI/IDE

connectors• Advanced Technology Attachment (ATA) is a standard

interface for connecting storage devices such as hard disks and CD-ROM drives inside personal computers.

• Many synonyms and near-synonyms for ATA exist, including abbreviations such as IDE and ATAPI

• original ATA was retroactively renamed Parallel ATA (PATA).

• Created 1986 by western digital.

• Speed: 16 MB/s originallylater 33,66,100 and 133 MB/s

THE 80 PINS ATA CABLE IS ALSO CALLED Ultra DMA IDE/ATA interface

COLOR CODES ON 80 PINS ATA CABLE

Color coding of the connectors is used to make it easier to determine which connector goes with each device:

• Blue: The blue connector attaches to the host (motherboard or controller).

• Gray: The gray connector is in the middle of the cable, and goes to any slave (device 1) drive if present on the channel.

• Black: The black connector is at the opposite end from the host connector and goes to the master drive (device 0), or a single drive if only one is used.

SCSI cable

• Widely used for RAID.

• SCSI is based on "SASI", the "Shugart Associates System Interface", introduced by that company in 1979.

• Internal SCSI cables are usually ribbon cables that have multiple 68 pin or 50 pin connectors. External cables are

shielded and only have connectors on the ends.

• Speed: 5 mb/s up to 640 mb/s.

SCSI in Action

SATA• It was designed as a successor to the legacy Advanced

Technology Attachment standard (ATA), and is expected to eventually replace the older technology (retroactively renamed Parallel ATA or PATA)

• Created 2003.• Speed: 1.5 Gbit/s, 3.0 Gbit/s • Style: serial

SCSI Bcurrently offers transfer rates higher than SATA, but is a more complex bus usually resulting in higher manufacturing cost.
