Is SATA backwards compatible with EIDE?

Is SATA faster?, more reliable?, by how much?

Not compatible.

It's not faster, however, an SATA bus is (sometimes? always?) 150 MBps
as opposed to the highest ATA bus which is 133 MBps. For a single drive
this doesn't matter, but for some RAIDs you can get a little bit better
transfer speeds.

The real benefit of SATA is smaller wires and smaller power adapters,
also I think any board that supports SATA has a built-in RAID but I
could be wrong about that.

NOTE: some motherboards come with adapters to plug an older IDE drive
into an SATA port, but I haven't seen one that does it the opposite way.

no

only on paper

no, less so because the connectors are more delicate

SATA is different than IDE; uses a different controller and connectors.

Thanks for your reply.

In regards to the adapters, are there adapters available to buy if the mobo
doesn't come with it?

SATA AND IDE use different types of interface. They are not really
compatible with each other. IDE is a parallel interface and SATA is a
serial interface.

SATA data transfer is faster. However, the IDE Transfer rate is fast
enough to support several hard drives and not suffer any slow downs due
to the transfer rate. So the faster transfer rate is really irrelevant.
An IDE drive has to write the data and read the data from the drive
and this takes longer than it does to transfer the data over the IDE
interface. So IDE hard drives can not catch up with the IDE transfer rate.

People will try to say I am incorrect. However I base my information on
articles I have read on www.htmlgoodies.com and www.anandtech.com .

My new abit MB came with an adapter, but it also stated the speed would only
be the same as the EIDE.
