Seagate Momentus XT 500GB Hybrid HDD Review (14)
23 January 2013
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
Conclusion: You are getting 2 years warranty period in this drive. If you are looking something as a replacement for your 5400RPM drive on your notebook and want more than 500Gigs of storage space with some advantage on the load times? Provided it uses SATA 6Gb/s, this is a good drive to shortlist.
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?
Excerpt: In the storage world, nothing matches a solid-state drive for speed, and nothing matches a mechanical hard drive for capacity and price per gigabyte. Recognizing these two great tastes would go great together, many vendors have attempted to find the perfect hybrid storage solution, with variable—and often clunky—results.
Pros: Significantly faster than a conventional mechanical HD; significantly more storage capacity than an SSD.
Cons: Not as fast as an SSD; less storage capacity than a conventional mechanical HD.
Summary: The Momentus XT 750GB is a more refined hybrid solution than its 500GB predecessor. The flash memory still only works as a read cache, but it's bigger, faster, and being used to greater effect. Seagate has upgraded the rest of the drive, too, giving it higher-density platters and a DRAM cache that's just fast enough to take advantage of the 6Gbps SATA interface.
Our exhaustive suite of tests has exposed a couple of weaknesses in Seagate's latest hybrid.
