Advice on single SATA drive installation

Hi, i'm installing this HDD (http://www.wdc.com/en/products/products.asp?driveid=552) as the single drive in my computer. I've got a pair of questions:

1 - Is SATA III backward compatible with SATA II? In other words, can I connect my SATA II drive on a SATA III port? If it's the case, should I use a SATA III cable or a SATA II cable?

2 - At the moment this HDD is going to be the only drive in my system. How should I configure it? I don't know much about RAID, I tried to read those FAQ (http://www.tomshardware.co.uk/forum/259807-14-raid) but they are still to complicated for me.

Thanks a lot,

PD: Anyone knows how can I access my posts from my profile page? I always end losing them...

Sata 3 is backwards compatible as far as I know. Sata 2 was backwards compatible, so I see no reason why 3 wouldn't be as well. A standard Sata 2 cable should suffice.

RAID is a Redundant Array of Inexpensive/Independent Disks (depending on who you ask). It requires 2+ drives. You will just format the disk, and install the OS. Nothing fancy.

On the forum index page, there's a button that says "My threads" and has a blue flag beside it.

Thanks for such a quick answer. I'll wait until someone confirms the backward compatibility and recommends the use of SATA II/III cables.

On the other hand, I've tried many times to access to "My threads" menu but it's always empty. It's a little annoying... Thanks again.

Alright, looked into it a bit more.

Also, the new standard is backwards compatible with SATA 3 Gbit/s.


SATA 3 is 6Gb/s, while SATA 2 is 3Gb/s, so that's what they're talking about :p 

As for the cable, the connector is the exact same. You won't be using the added bandwidth, so the SATA 2 cable will indeed work.

It's all crystal clear. Again, thanks a lot for your time.

Here's a quick summary:
SATA-I = 150 MB/second
SATA-II = 300 MB/second
SATA-III = 600 MB/second


This HDD:
http://www.wdc.com/en/products/products.asp?driveid=552

... is SATA/3G aka "SATA-II" NOT "SATA-III":


Click on "Specifications" to confirm:

Transfer Rates
Buffer To Host (Serial ATA) 3 Gb/s (Max)


Don't confuse SATA-III with 3 Gb/s.

The SATA-III standard is 6 Gb/s abbreviated "6G".


There are only a very few WD 7200 rpm HDDs that support
the 6G interface e.g. search for "6 Gb/s" here:

e.g.:

http://www.wdc.com/en/products/products.asp?driveid=855

Hope this helps.

Thanks, you've confirmed what I was expecting. Even tough, I asked about that because my motherboard (Asus Crosshair IV Formula) has six SATA III connectors versus a single SATA II connector and, in addition, they are much better placed.

On the other hand, I've heard that "normal" HDD's like mine don't take profit of the total available bandwith even with SATA II connection. So, my intention is to connect my HDD to a SATA III port using a SATA III (or SATA II?) cable.
