types of drive interfaces Flashcards
how are hard drives and optical drive manufacturer
Hard drives and optical drives are manufactured with different interfaces that are used to connect the drive to the computer.
what needs to be the same when installing storage on a computer
To install a storage drive in a computer, the connection interface on the drive must be the same as the controller on the motherboard.
IDE
Integrated Drive Electronics, also called Advanced Technology Attachment ATA), is an early drive controller interface that connects computers and hard disk drives.
how many pins on an IDE
an IDE interface uses a 40-pin connector.
EIDE
Enhanced Integrated Drive Electronics, also called ATA2 is an updated version of the IDE drive controller interface.
what does IDE support
IDE supports hard drives larger than 512 4B, enables Direct Memory Access (DMA) for speed, and uses the AT Attachment Packet Interface (ATAPI) to accommodate optical drives and tape drives on the EIDE bus
how many pins on an EIDE
EIDE interface uses a 40-pin connector.
PATA
Parallel ATA refers to the parallel version of the ATA drive controller interface.
SATA
Serial ATA refers to the serial version of the ATA drive controller interface.
how many pins on a SATA
SATA interface uses a 7-pin data connector.
eSATA-
External Serial ATA provides a hot-swappable, external interface for SATA drives
what is hot swapping
hot-swapping is the ability to connect and disconnect a device while a computer is powered on.
what does eSATA interface with
the eSATA interface connects an external SATA drive using a 7-pin connector.
how long can an esata cable be
the cable can be up to 6.56 ft (2 m) in length.
SCSI
Small Computer System Interface is a drive controller interface that can connect up to 15 drives.
