Momentus Series Technology Features

SmartAlign Technology for Easy 4K Migration

A change is coming to the hard drive industry. The smallest sector of organized data on a drive is moving from 512 to 4,096 bytes. The new format, known as Advanced Format (AF) 4K, offers advantages like increased efficiency, but migrating your drive can be challenging. Luckily, Seagate is ready to help you make a seamless transition to 4K sectors. Seagate's SmartAlign technology automatically does the work of AF migration in the background. The drive's performance is not affected, and there is no need for time-consuming utilities required by other AF-enabled drives.

I bought it to use in my ps3 and had no difficulty replacing the old one. I surprised my husband (with the replacement already loaded with all of his settings, saved content) and he couldn't have been happier! Awesome product with a better price!

it gave my ps3 room to breath and at the same time i can put all of my games on it with room to spare. it was so very easy to install. highly recommended!

since adding this hard drive to my ps3 it has given me way more memory and it has been working like a champ. It has made my ps3 feel like it was brand new again and right out of the box from game stop where i bought it brand new. with this hard drive you will have the same feeling all over again.

I should have gotten one of these a long time ago. I've been saving important stuff on a flash drives for years. Now I can put everything in one place. So far it is working great. I plug it into our computer just about everyday to make sure it's working. I hope it doesn't fail .... EVER. I'm enjoying the extra space. It's keeping my creative writing projects and ideas safe for now.

I've had a few people recommend that I should stay away from Seagate. Personally, i've never had any problem with Seagates HDDs. Works as expected and comes with a two year warranty. What more could you ask for? Read write speeds are about average for a 5400 rpm hdd. Nothing spectacular. Gets the job done.

Amazon is very competitive. I needed a hard drive fast and didn't want to pay more for it than other specialty houses such as Newegg...turns out this drive was cheaper than the same model at Newegg, and arrived in 2 days with PRIME...Great job. I downloaded Seagates seatools to duplicate the old drive to the new one and the drive was replaced in no time.

By Think on January 9, 2012
Installed this in an upgraded Thinkpad T60 with Windows 7. The hard disk was new, not refurbished. Worked perfectly initally. HD started hiccuping and my system diagnostics warned me my hard disk was failing, at about 9 months after installing. It lasted another 2 months and now I'm waiting for a new HD to arrive in the mail to get my computer running. We'll see how Western Digital does.... I would consider myself a very shrewd computer user and I maintain my system very well, but still the Seagate was, unfortunately, a let down.

After I got this I opened it up and found this very shiny disc inside. When I looked into it I could see my own eyes in the reflection and gaze into them deeply. This kind of creeped me out and I dropped the hard drive. After that it didn't seem to work, but I'd guess that the cat litter inside the case is more to blame for this than anything else.

This data HDD arrived fast and was neatly packaged. I actually got a 320 gig. It was simple to install and added a lot of extra space the old ps3s don't come with. Worth the money for sure. Would recommend intercoolers for old systems as well.
