Interesting. Statistically how do data transfer rates compare?

Not crazy over the SATA connectors either.
SATA or Serial ATA has another design flaw
in that by nature serial data transfers can never
be as fast as parallel.

I have had a disk connection problem which seems to relate to
failing sata cables. The BIOS has failed intermittently to detect
one or both hard drives. The problem was more obvious with the
master drive so I replaced the cable 14 days ago and there was no
further problem until this morning. The problem this morning was the
slave drive so I have replaced the cable for that drive. It has now
been working for a bit over two hour. The problem first became apparent a
month ago when I found the system
would freeze after it had been running some time. Resetting sometimes
worked and sometimes resulted in a failed boot. Eventually the system
would boot but the problem would happen again some hours later or
the next day. Sometimes there have been Event Viewer reports -mainly
ID: 11 referring to the Controller. Often the problem is unreported.
This is probably because the Error is occurring before Event Viewer
starts. From a friend I got these comments.

"In my view, the SATA 'Connector' is an engineering blunder. A
sort-of flat
sleeve slides over a notched part on the edge of the board whereupon
sit some exposed/un-insulated traces. Flat conductors encased within
a plastic bit are slid into contact with them. There is no mechanism
but friction to keep the 'connector' in place. Entirely inadequate.
It is not designed for repeated make/break insertion/removal. If
subjected even to a low number of
such operations (design spec is 50), it will fail. (5 000 for an
eSATA connector). If I have to repeatedly disconnect-connect a drive
during testing, I replace the cable as a matter of routine."

I am interested in knowing whether others have encountered this
problem and how common place it is?

TIA
