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 this hard drive to replace the 40GB hard drive on my PS3. I was almost about to trade mine in so I could buy a PS3 slim with more capacity. Searching for buying options I found out that you could upgrade your hard drive without voiding the warranty, and in only 20 mins with only a screwdriver and a steady hand. I was running out of space fast due to downloading movies and TV episodes. I reviewed several other drives before choosing this one. The Seagate stuck out above the rest for two main reasons:

-First being that the original hard drive in my PS3 is a Seagate, so if Sony trusts them so do it. I also decided to stick with 5400 rpms because that is the spec for all PS3s, and the 7200s have gotten some poor reviews for noise, heat, and no real gain in performance. Also I heard some 7200's are a little thicker than the 5400's therefore some do not actually fit in the PS3's expansion bay.

-Second, reviews (on another site) rated it very high, and nobody had had a problem with it. Also the prices on the SATA 2.5 inch drives have all gone down in the last few months so that was enough reason to make the investment. I highly recommend this hard drive for use with the PS3, it is quiet, runs cool, and was installed with ease.

INSTALLATION: If you are going to upgrade your hard drive use a #1 phillips screw driver (#2 is the most common) or you will strip the small screws that secure the drive to it's cradle. If you strip or bugger those screws you are looking at least a few weeks to order them from Playstation. Also, make sure you have a compatible (FAT32) USB flash drive so you can download the most recent update. I have used both Sony and SanDisk USB drives and they work fine.

If Anybody Is Looking To Upgrade Their PS3 System, This Is The HDD To Get!! It's Been The Most Highly Recommended HDD On The Market and Sony Also Uses Them In Their Newer Systems Like The PS3 Slim. No Compatibility Issues At All. As With Some Of The Customers On Here Who Purchased This HDD, I Totally Agree With Them. Get This Seagate 320GB Hard Drive If You Want The Extra Space For Your Games, Videos, Music, Movies and Photos You May Have. This 320GB HDD Replace My Old 80GB HDD.

If You Want A Smooth Transition From Your Old PS3 HDD To A Larger 320GB HDD, Just Follow These Simple Steps:

First, Make Sure You Have An External Hard Drive That Is Large Enough To Backup and Store Your Old Data From Your Old PS3 HDD. Mine Was An 80GB HDD From My PS3. On Your Playstation 3 Settings Menu, Look For The Application That Says: System Settings. Next, Look For The One That Says: Backup Utility. From Here, You Must Backup Your Old PS3 Hard Drive System Data Onto An External HDD (Make Sure The External HDD Is Large Enough To Fit All Of Your Old PS3 HDD Data Before Removing The Old Hard Drive From Your System. Just Follow The Instructions On Backup Your PS3 Data. Depending On The Size Of Data On Your PS3 Old Drive, It May Take Between An Hour to 2 Hours. Once The Backup Is Complete, Shut Off The PS3 and Unplug It To Prevent Any Electrical Hazards or Damaged To Your Playstation 3 System.

Second, You'll Need Either A USB Flash Drive or Still Your External Hard Drive and A Computer For Making 2 Folders Called "UPDATE" and the Other Called "PS3" On Your Computer's Desktop. Internet Access For Downloading and Installing The Latest Firmware From SONY's Playstation Network WebSite: [...]

The Latest Firmware As Of July 14, 2011 Is 3.66.

When my 60GB PS3 abruptly shutdown with the "blinking light of death", I knew it wasn't good. Internet research pointed (if I was lucky), my HDD crashed and needs replacing. This was a great value, without spending the hundreds of dollars while losing my backwards-compatibility. Interchanging the PS3 HDD is super-simple. One black screw, and you simply pull it out of the bay. 4 little screws off, and you'll move the drive harness to your HDD, before re-screwing and sliding back in.

But, I wasn't lucky. The blinking light of death mocked me.

I wasn't about to spend at least $140 and weeks without my home entertainment center. So I bought this: PlayStation 3 160 GB and replaced the factory drive with the 320GB. In short, spending an extra $50 saved me an extra $50.

Note: The HDD harness from the 60GB chassis is not compatible with the 160GB model. It still requires removing one black-headed screw to get to the bay. Just remember to return the little plastic strip *before* returning the screw into its rightful place.

Tips:
Go to the Playstation web site and download the O/S update.
Using a USB flash drive, make a directory named "PS3", underneath that, create a sub-directory named "UPDATE"
Make sure the directory names are capitalized.
Copy the single update file into the UPDATE folder.
Plug in a controller via a USB cable with the PS3.
Plug in the flash drive into the PS3 USB port, start the PS3 and read the prompts carefully.
(Don't just thumb through them. You'll need to hold specific keys down in unison for 5 seconds.)
Your new drive will format, and voila! A new high-capacity PS3.
