Misrepresentation of fact!

[ayoub_ibrahim]

happened to notice this on the back of a Belkin ATA66 retail ide cable pack.


Notice the writing in bold : Using this cable with an Ultra-33 Drive can increase performance by up to 90% when compared with a standard IDE cable!
I wonder how they can make such a "bold" statement with obvious misrepresentation of fact.

I'm guessing they meant Ultra66 and are just stupid.

Although one could argue that the crappy 40-pin cables won't allow anywhere near 33MB/sec. throughput so these WOULD help U33 drives.

Of course then we also are overlooking the fact that even the fastest Ultra100 drives nowadays only burst at 25MB/sec.

exactly Jason. They proably mean with a 'regular IDE cable' one that is very bad quality, and suffers enormously from interference. They don't state what the chance is that you're using such a cable right now however!

Up to 90%? Hell I figured I could find a couple examples of where I have attained 1000% improvement in performance. Really.

Hey Gurm,
I think you'd better check out IDE again:

They quote 37MB (35.3 when you correct to a true MB) sustained, and I bench at 24MB/s under linux, and that's with the drivers running at UDMA33 (working on compiling new drivers for the 686B chip).

Guess what happens if you conect a UDMA66 HDD to a UDMA33 mainboard through a UDMA66 cable?

Answer: Corupted data!

This happened to me once.

The Stupid Quantum HDD thought that it could transmit at UDMA66 and that did'nt my Mainboard like!

[Wombat]

I'm not so sure that it was the HD's fault. The drivers can limit transmission speed, and in your case they seem to have failed.
