Over at Hardware Secrets, they have published a review of the Seagate Barracuda 3TB Hard Drive...

"Most enthusiasts will favor SSDs for their main boot drive rather than a mechanical hard drive thanks to the vast performance benefits available. However, there is still a large market for high performance mechanical drives which offer a much larger capacity for storage of large files. Today we are going to look at the latest Barracuda hard drive from Seagate, which offers no less than 3 TB of storage space."
