Need Education on SATA Cables

I'm new to SATA and would like to understand what are the different
standards for cables. As I understand it the SATA standard provides for
1.5 Gbps and 3.0 Gbps interfaces. Questions are:

1) Does each interface require a different type of cable?

2) If you use a SATA 1.5 Gbps cable on a SATA 3.0 Gbps device, does it work
at 1.5 Gbps?

For any kind of desktop application, I just don't see how anyone would need
more than a 1.5 Gbps device. That's more throughput than you get even get
from the rotation of a 15K drive with all the data laid out sequentially in
64K blocks!


1. Sata 150 or sata 300 cable?

2. SATA HDD only works with SATA to eSATA cable?

I have a 750 GB sata 3.0 HDD which i'm trying to connect to a sata RAID
card or motherboard. I've connected my hard drive using an sata cable
to both my motherboard and my raid card. When i try either this
prevents windows froms starting. The motherboard sata is 3.0gb/s, the
raid card is 1.5gb/s. I've tried all jumper settings and made sure all
cables are working. I have another sata drive that works with
everything. The hdd that works is a samsung, the hdd that doesn't is a
western digital recertified.

I have an sata enclosure which has its own powersupply and a sata to
esata cable. My hdd above only works when i put the hdd in the
enclosure and connect the sata to esata to the motherboard. The
enclosure does not work with the raid card.

Any ideas?
