ATA /66??????

[jl123]

Hey what does this mean? ATA/66
Ultra DMA/33
Are they some sort of interface for hard drives?

What are all the hard drive interfaces?

Thanks so much
As you can tell i have to know everything http://www.sysopt.com/forum/smile.gif

ok i'm not totally sure but your right they are types of protocols/transfer/systems.

basiclly most hard drives that we are used to are ****/33 know as i'm sure you might of guessed ****/66 is faster the transfer rates of these drives is amazing benchmarked they fly. The reason for the stars is that as far as i'm aware the letters mean the same thing:

ultra DMA
UDMA
ATA

Ultra DMA


Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer's data paths (or bus) to the computer's random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a rate of 33.3 MBps (megabytes per second), twice as fast as the previous Direct Memory Access (DMA) interface.

Ultra DMA was developed as a proposed industry standard by the Quantum Corporation, makers of hard disk drives, and Intel, makers of chip sets that support computer bus technology.

Ultra DMA support in your computer means that it will boot (start) and open new applications more quickly. It will also help users of graphics-intensive and other applications that require large amounts of access to data on the hard drive. Ultra DMA uses Cyclical Redundancy Checking (CRC), offering a new level of data protection.

Because the Ultra DMA protocol is designed to work with legacy PIO and DMA protocols, it can be added to many existing computers by installing an Ultra DMA/33 PCI adapter card. Ultra DMA uses the same 40-pin IDE interface cable as PIO and DMA.

ATA

IDE (Integrated Drive Electronics)


IDE (Integrated Drive Electronics) is a standard electronic interface used between a computer motherboard's data paths or bus and the computer's disk storage devices. The IDE interface is based on the IBM PC ISA 16-bit bus standard, but it is also used in computers that use other bus standards. Most computers sold today use an enhanced version of IDE called EIDE. IDE gets its name because the disk drive controller is built into the logic board in the disk drive.

IDE was adopted as a standard by ANSI in November, 1990. The ANSI name for IDE is Advanced Technology Attachment (ATA). The IDE (ATA) standard is one of several related standards maintained by the T10 Committee.
