Summary: I bought this drive to backup all of my computers. It has so much space in it that I was able to put all of music, movies, pictures and space for all of the families backups. I would recommend this to anyone. I have 0 problems and I give it a big A+.
Summary: It's a hard drive. It doesn't have to wow me, it just has to work. And so far, it does. My first HD was a Western Digital which failed after three years of daily use. I hope this one lasts just as long (and you'll be hearing about it here if it doesn't). It seems quiet, and I like the lower power drain. Doesn't seem to have any major performance hits or anything like that that you would expect from a "green" product.
Summary: Now the warranty is only 2 years for Green drives (previously 3 years), but Seagate offers only 1 year. I had to update 'Intel rapid storage manager' because the OS (Windows 7 Pro) only showed the disk as 746GB unit. I'm using it as secondary disk, mostly for backups.
