About SATA, SATA II and SATA 3.0....

At this point I´m utterly confused and a bit annoyed too.
I have an old motherboard and need a new hard disk, I had the impression I could attach any SATA disk to the motherboard, I believe is SATA (the first), with the only downside being the disk not working at it's full capacity.

All the disks I've seen around so far are SATA 3.0 ... Today I called a vendor and asked him if there were some kind of incompatibility attaching one of these disk with an old motherboard and he advised to not do so because i would kill the disk rather quickly... :inquisitive:

Is this true? Anyone knows?

Check with your motherboard vendor.

I would consider a different vendor than whichever one gave you this rather odd bit of technical advice... SATA is explicitly
designed for compatibility between revisions of the spec. Correct implementation should therefore have no trouble handling any SATA-3 /SATA/ SATA-2 mix you care to throw at it; which is to say that any manufacturer claiming premature disk death by SATA should be considered a snakeoil salesman.

Thanks guys! Odd advice from them really, more considering here you need to be careful when they say something is 100% compatible when clearly it isn't in their thirst to sell ;)

Now I'm tempted to visit and give them five good reasons to not scare their customers with bad advice!

the vast majority of drives around right now are SATA 2, although they are sometimes labelled SATA 300 (MB/sec) which is admitedly confusing.

Exactly, here in the local market they are labeled SATA 3.0 Bought one of these, a 500 gigs one and it doesn't work, the mother/BIOS refuse to see the Disk attached... bad thing... I'm sad...
