Ide With 40 Wire Cable Transfer Speed

Only the old optical drives use the 40 wire cable the recent optical drives operate at ultra dma speeds and need the 80 wire cable.

Ide with 40 wire cable transfer speed. Both types of cables continued to use 40 pin connectors. Each cable has two or three connectors one of which plugs into a host adapter interfacing with the rest of the computer system. This basic model endured through the ata 33 specification. Pictured here are the two cables the 80 wire and the older 40 wire ata ide cables.

The 80 wire cable provides one ground wire to each signal wire. The 80 conductor cable is about the same width as the older style because thinner gauge wires are used to make up the ribbon. The remaining connector s plug into storage devices most commonly. The parallel wire transfer mode reached its limit with the speed of 133 mb s.

The traditional cable uses 40 socket connectors attached to a 40 or 80 conductor ribbon cable. A comparison of the wires used in 80 conductor and 40 conductor cables. My pioneer dvr 111d about 6 months old operates at ultra dma mode 4 throw out those 40 wire things and get the 80 wire jobs. Data transfer speed for ide ranges from 5mb s up to 133mb s ata100 133.

Note that mb is megabytes and gb is gigabits similar to pata 133. Parallel ata cables transfer data 16 bits at a time. Sata took off where ata stopped as far as speed is concerned. The 80 wire cable has 2 wires per pin which acts as both a ground and as emi protection.

For most of ata s history ribbon cables had 40 wires but an 80 wire version appeared with the introduction of the ultra dma 66 standard. The first generation of sata was 1 2 gbit s 150 mb s. There is a reason for this. Comparison between 40 pin and 80 pin ide ata data cables.

This reduces the effects of electromagnetic induction between neighboring wires and enables the 66 megabyte per second mb s transfer rate of. As you can see the one on the left the newer 80 wire cable has very small wires running from connector to connector conversely the 40 wire cable has larger wires. The difference between this 80 wire cable and the normal 40 wire ide cable is that it includes a ground wire between each. With the introduction of ata 66 the 40 wire cables were replaced by 80 wire cables for even faster data transfer speeds theoretically reaching up to 66 6 megabytes per second.
