1 One gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes when referring to hard drive capacity.
The Seagate Momentus XT drive offers hybrid storage with Adaptive Memory technology, enabling the drive to deliver higher capacities up to 500 GB and SSD-like performance. The Momentus XT drive is designed for all standard laptop PCs and is OS-, driver- and software independent, making this drive easy to integrate and easy to use. Adaptive Memory technology enables the drive to tailor its performance to the user. Whether you are gaming, editing digital media or crunching numbers, the performance is optimized and ready for your next move. Adaptive Memory technology is a Seagate data management technique that constantly monitors and quickly recalls data usage and preferences. It places files and data that the user will likely access again and again into the solid state portion of the drive. When the user requires the data or application file, it already sits in an instantly accessible location, thereby customizing system performance for the user. Constant monitoring dynamically improves overall response time based on personal usage. You can perform at your best no matter how you use your laptop PC.

Customer Reviews
I have the 500GB version of this drive. I also use and have used SSD's with SLC and MLC flash, JMicron controllers, Samsung Controllers, Barefoot controllers, and SandForce controllers on 32-bit and 64-bit operating systems. I've used several generations of Raptors, and 3Ware RAID controllers. I'm not saying that to brag, I'm saying it to point out I have a reasonable basis for comparison and expectation.
Here's what the drive does well: It's alignment- and OS-agnostic, so it does not care if you run it unaligned on older XP systems. It will, over about 5 cycles, learn what you do and optimize it. You will notice your system boots much faster. It excels on systems where you boot into your OS and do the same basic tasks, say, open MS office and Firefox and Outlook.
Here's what the drive does not do well: If you are constantly changing what you run on your computer, your drive will constantly be "learning" what you do. I have also found it does not do well with remote desktop apps that are constantly caching image data.
Here's what the drive does that makes it no better or worse than any other mechanical drive: If you are using the drive to store music or videos or such, they are going to go the the platters. Then it's just another very good, high performance 7200RPM notebook drive. Nothing wrong with that at all.
Here's the KILLER APP reason to buy this drive: I took a 32-bit Vista Home Premium laptop that was so congested and clogged with programs, leftovers of removed programs, fragmentation, you name it, and just cloned it to this drive. The mechanical drive it was on took literally 5 minutes to get to a useful state on the desktop. This drive, after about 5 boots, learned that our family needed Vista OS, Chrome for Farmville, and iTunes. We now have 30 second boots and even though the drive is still loading services and such, we can launch apps immediately at the desktop. Our primary apps either snap open, or in the case of iTunes launch about 3x faster. It's not subtle, it's huge.
If you want a drive that does not have alignment issues with older OS's, and is used primarily on a computer that does about the same sorts of things over and over, this drive will make a huge difference for you. And since it's SLC cache, it's enterprise-class durable in that regard. Also, it mirrors its flash to the mechanical drive, so if the flash fails, it just becomes a regular mechanical drive, sort of like a run-flat tire.
I've read a lot of reviews, some good, some bad. I think some people have this idea that the product will speed everything up all the time, and this sets bad expectations. What this drive will do is cache often used data, such as core Operating System files used at boot and commonly used applications, and store that data in its 4GB SSD-like cache. If your drive already reads and writes pretty fast, in the neighborhood of 75-100MBps (megaBytes not bits), other than boot up and application loading, you aren't going to notice much of a difference.
I use Apple's OS X Snow Leopard, and it definitely boots faster (1 minute 30 seconds prior to this disk, now 55 seconds from power on to ready + all my startup apps running), and commonly run applications also start up noticeably faster.
I upgraded from a bit slower drive, so I see some performance gain there, but nothing huge.
Overall I got the disk read speeds I was looking for -- faster boot, faster common app loading, and an overall boost in performance by upgrading from a slower drive altogether.
This drive won't change your life, unless you are booting several times a day or loading the same data repeatedly. It's a fine drive with the benefit of faster boot and common app loading times, nothing more.
