Support Note: Like most technologies,
IDE devices have their own vocabulary.
The following terms may be helpful as you read
this manual.
IDE (Integrated Drive Electronics) – A standard
electronic interface between a PCI-based system’s
memory and disk storage devices. EIDE, an
enhanced version of IDE, is commonly used in
PCI computers.
ATA (Advanced Technology Attachment) –
The “official” name used by the ANSI (American
National Standards Institute) to describe IDE
technology.
Ultra ATA/66 – Ultra ATA/66 is the latest drive
data transfer protocol used in today’s disk storage
devices. It incorporates ATA/IDE technology with
data transfer rates up to 66MB/sec, effectively
doubling the burst data rate of the previous
transfer protocol, Ultra ATA/33. Ultra ATA/66
provides greater system throughput and data
transfer integrity.
