It only costs around 10-15€ more than the 500GB variant (which uses 500GB platters, much slower), and you get twice the storage and a crapton more of performance.
Really? NICE! If you prefer Western Digital for some reason, the WD10EZEX (1 TB Blue) gets great sequential speeds too at 150-160 MB/s. Not quite as good, but an option if the price is lots better. Unfortunately WD Blacks are the only way to get a decent warranty (5 years). Their other models and most other brands offer 2 or 3 years usually. But the WD Blue for sure uses one platter, and it's likely that the (2 TB) Barracuda uses two, giving you fewer points of failure.
EDIT: Forgot to mention that SATA speeds don't really matter for HDDs. You might pick up a tiny bit of performance from the cache, but it's negligible. As long as the port is SATA II, the HDD won't be bottlenecked.
