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: 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.
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.
Hybrid Storage Roundup: Seagate Momentus XT vs. OCZ RevoDrive Hybrid vs. Intel Z68
5 December 2011
Excerpt: Back in 2006, storage tech talk was intermittently buzzy with a few different innovations. One was wrapped around the pending release of Windows Vista, particularly two bullets on its feature list: ReadyBoost and ReadyDrive. In parallel with all of the Ready_____ talk, many tech pundits asked why it would be necessary to have the flash talk to Windows through special drivers. Why couldn't the flash memory just act like a larger RAM cache already present on?
