SATA:
The ultimate connection standards, using a
serial data for transmission bus. Noticeably faster and efficient than IDE.
There are three versions, one with SATA transfer rate up to 150 MB / s (now
discontinued day), SATA 2 up to 300 MB / s, the most widespread today; and
finally SATA 3 to 600 MB / s which is starting to do well in the market.
Physically is much smaller and more comfortable than IDE, and allow hot plug.
IDE:
Control devices massive data storage, such as
hard disks and ATAPI (Advanced Technology Attachment Packet Interface) Until
about 2004, the main standard for its versatility and affordability. They are
flat, broad and elongated.
SCSI:
They are prepared for hard drives large storage
capacity and rotation speed interfaces. Are presented under three
specifications: Standard SCSI (SCSI Standard), Fast SCSI (Fast SCSI) and SCSI
Wide-Fast (Fast-Wide SCSI). Its average access time can reach 7 milliseconds
and speed sequential transmission can theoretically reach 5 Mbps on SCSI disks
Standards, the 10 Mbps Fast SCSI disks and 20 Mbps on Fast-Wide SCSI disks
(SCSI-2).
