Brian,
My information (I assume) reflects a sustainable transfer rate between disk
buffers and central memory. We both know there's a lot more to disk I/O
than buffer transfers.
I am building a web service based on RH Linux 6.0. I'm using a 450 MHz
Pentium II w/ .5GB.
I have invested in two WD
I purchased two UDMA/66 cables from Fry's Electronics. There stores are
located throughout the west. They were different lengths and prices. The
average price was ~$20.
It's my understanding that these cables are needed for both UDMA/33 and
UDMA/66 drives to transfer at ratred speed as follows:
