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 been one of the popular brands as far as computer peripherals and accessories are concerned. Recently the company announced their Momentus XT Solid State Hybrid Drives in capacities of 250GB, 320GB, 500GB and 750GB. With SSDs and HDDs in the market, these Solid State Hybrid Drives (SSHDs) aim to get the best of both worlds. Let’s have a look at how the Momentux XT 750GB performs.
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
Conclusion: If you have the extra money to spend, this drive is definitely one of the fastest mechanical disks that we’ve ever tested. It would be a significant upgrade to a laptop that has a 7200rpm HDD in it, and a mind-blowing upgrade for a laptop that is saddled with a 5400rpm HDD. Seagate made a very, very savvy move in creating this drive.
