Conclusion: Let us summarise the most important positive and negative points below: The Momentus XT hybrid drive offers very good value, with great performance, and storage capacity. It is really quite remarkable how fast this little drive is at booting an operating system, and launching applications. Give this drive a little time to learn your working habits and it will reward you with very snappy performance. The Momentus XT is also a very quiet drive in operation.
Pros: Fast operating system start-up and shutdown times., Fast application loading., Large capacity for a 2.5 inch drive., Low cost per Gigabyte compared to an SSD., Whisper quiet operation
Excerpt: Seagate has sent the generation Momentus XT Drive with 750gig of storage space. Compared to its predecessor (1st Gen Momentus XT ST95005620AS drive), ST750LX003 Seagate Momentus XT 750 GB is with larger Flash NAND, SATA 6Gb/s interface- anything that one can expect from a successor. Does it succeed and even fair better than the other drives is something we’ll need to see as the review progresses.
Summary: The Momentus XT is for gamers that don’t have room for an SSD and a regular drive or can’t afford a large capacity SSD. At about $180 at time of writing, it’s not much more expensive than a regular 2.5″ 7200 RPM drive of the same size. It’s definitely worth spending the few extra dollars and getting the hybrid drive if you plan on using the drive as a boot volume or plan on running applications from it.
Summary: The second-generation Momentus XT performs much better than the first-generation model, even when the caching system isn’t used. In our tests, the performance advantage of the second-generation drive was between 17% and 100% over the first-generation drive in this scenario, depending on the test.
When the drive had time to “learn” how you use the computer, its performance jumps between 80% and 152%, which is really impressive.
Conclusion: One of the key features of the Momentus XT is the ‘Adaptive Memory Technology’ that’s basically a self-learning algorithm that notice your most used programs and stores their data on the cache. So every time you run those programs again, they will be loaded as quickly as an SSD since the data is being read directly from the 8GB NAND Flash.
Conclusion: The Momentus XT is a hybrid in the best possible sense. You get the capacity of a traditional disk, along with (some of) the speed of an SSD, without breaking the bank.
Pros: Flash memory means faster speeds. Drive adapts to your usage.
Cons: Moving parts means it’s still susceptible to damage, just like your regular drive. Speeds up boot times, but transferring files is pretty much the same as traditional drives. Higher cost-per-gigabyte.
Summary: If you want the fastest performance possible, then a full-fledged SSD such as the Samsung 830 Series ($209 for 128GB) is still the way to go. However, if you need more than 128GB of storage and can't afford to mortgage the farm for a 256GB or larger SSD, the Seagate Momentus XT is your best upgrade option.
Pros: Fast boot times, Speedy app opens, Lower cost per GB than SSDs
