I dropped by at Seagates homepage. I found it hard to see wich was the better drive ... 7200.7 or Baracuda V. So I send an email to thier support. Here is the answer I got

Hello Immanuel,
The Barracuda V models are being replaced by the newer Barracuda 7200.7
series. They both have specifications on our website, but they made the
website where some are a little hard to find. We apologize for this
inconvenience, and will try to direct you to where the specifications are
located.
The main differences are that the internal transfer rate on the Barracuda
V models is up to 570 megabits/second, and on the Barracuda 7200.7 series,
it is up to 683 megabits/second. Another thing to look at is the average
seek time. It is 8.5 milliseconds on the Barracuda 7200.7 models, and 9.4
milliseconds on the Barracuda V. Other than that, the amount of platters
and heads, depending on the model, is less on the Barracuda 7200.7 family,
as they are putting up to 80 GB per platter on the 7200.7, and only up to
60 GB per platter on the Barracuda V models.
Some models are still transitioning to newer models, so they may or may
not be available through your dealer.

The Barracuda 7200.7 series data can be found at
http://www.seagate.com/cda/products/dis ... 81,00.html
The Barracuda V series data can be found at
http://www.seagate.com/cda/products/dis ... 61,00.html
By the way, the warranty is only one year on all of our ATA drives, and
Serial ATA drives, except for the Barracuda 7200.7+ series, which are
three years, not the 7200.7, which are still one year warranty.
Currently, the only Barracuda 7200.7+ series we are aware of being
available in the distribution channel are the ST3120026A, and the
ST3160023A.
