Information on the change in the Hard Disk Drive from a PATA Hard
Disk Drive to a new SATA Hard Disk Drive.

In recent years, the mainstream of the HDD standard has been shifting from PATA to SATA, and the HDD
manufacturers are preparing to discontinue the PATA HDD. Accordingly, imageRUNNER series and
Encryption Boards that have been designed to support the PATA HDD and will need to be modified to
support the SATA HDD as soon as the stock of the PATA HDD runs out.

Thanks for that info Tekcat.

I thought it funny that a serial technology like Sata could outperform a parallel technology like pata. That's like saying 32 cars can travel faster on a sinle lane road than on a 32 lane road. But the reason sata has become the dominant technology is as follows:

Basically, with parallel data paths, transmission speed along those conductors varies due to physical differences in the lines (manufacturing quality and damage are two reasons that spring to my mind). This variation gets more important as transfer rates go up and bit times go down. Coordinating the bit arrival times (when has a byte arrived?) requires additional logic circuitry.

It is much simpler to time the arrival of bits along a single serial path (with near constant delay) than to match up the bits of a parallel byte (arriving at different times), so bits can be transmitted at a faster rate. Eventually, the parallel benefit is offset entirely by the overhead due to synchronization of the parallel bits.

The performance of parallel buses can be improved in several ways, and system board buses take advantage of this. The conductors can be shortened, widened, made more uniform, and protected better. These all increase cost and would make cables larger and less flexible.

For today's transfer rates, it is now quicker and cheaper to design and manufacture faster serial data cables than to design and build the synchronization circuitry needed for parallel transmission. In addition, the synchronization logic increases power consumption, and thus heating.

Another benefit is that the cables are smaller, which restrict air circulation less, reducing possible hot spots in a computer enclosure. Also, smaller cables are generally more flexible.

Boy am I ever a geek to even want to know this stuff-LOL

[pga]

i believe the main reason why want change to SATA is HDD manufacturer will discontinue IDE/PATA HDD soon. The main feature for SATA is transferring speed more faster than IDE/PATA.
Anyhow,thx for your information. Appreciate...

I thought it had something to do with a Flux Capacitor????

The flux Capacitor...

Ha.

I used that on a customer. LOL

He believed me. HAHA

Hundreds of non working flux capacitors are recycled every year,/
