The PCB printed circuit board has all soldered components facing the drive body to shed heat and protect components from getting hit accidentally. Seagate does expect this to change eventually, but until it does the Momentus XT’s sales potential is limited. Improving platter density only really addresses sequential access performance, without faster spindle speeds, random access performance remains mostly untouched from one generation to the next. Final Thoughts and Conclusions. Let’s say you’re running a library with thousands of books and thousands of users.

To keep performance data consistent with other drives also benchmarked on this system, we maintained the same clone image across the pair of Momentus XT GB’s as well. Momfntus with electrons is far quicker than waiting to reposition a head over a spinning platter.

Seagate will eventually use the larger NAND to cache writes as well as reads. For the average user, trying to translate random 4K write speeds into an everyday situation is pretty difficult.

The improved performance does 75 equal what an SSD can do but it’s close and, for me, I find the price-to-value of the hybrid drive to beat a comparable sized SSD by a lot. Single partitions can take up the entire capacity or a portion as small as merely 8GB. Caches exist in several locations in any modern day computer, both in hardware and software.

Seagate Momentus XT 750GB Review

Our next set of synthetic benchmarks look at the inner and outer edge performance of the GB Seagate Momentus XT, with momentuss outer edge being fastest and the inner edge being slowest. I’ve played with an early version of this firmware and it does improve performance tremendously.


The nice part is that this is all OS agnostic and is handled on the drive itself so there are no worries about incompatibilities. While the Intel XM still beat out the crowd with an overall time of In the next test we record the average power consumed over a small range of synthetic benchmarks. Initial Run OS on test disk. Most OEMs want two suppliers for momentjs parts like display panels or hard drives.

Requesting a book not located at the moentus desk would still take the same amount of time.

Seagate 2nd Generation Momentus XT (750GB) Hybrid HDD Review

To see peak performance through the caching mechanism we looped the benchmark four or five times in succession before the speeds leveled off. See all 2 brand new listings. In this trace we recorded 2,MB being written to the drive and 1,MB being read. The drive isn’t loud by our standards, idling at 2. For any workload that isn’t perfectly sequential in nature, not addressing random access performance means that improvements to platter density will provide increasingly smaller performance improvements.

Startup power requirements neared almost 1A, measuring 4. To quantify the performance improvement over the previous generation as well as its place in the HDD-SSD continuum, we turn to a mix of application based, trace based and synthetic benchmarks.

Seagate GB Momentus XT Solid State Hybrid Hard Drive Review –

On the other hand by only caching reads, it means that writes to the hard drive are no faster than they would be on a xtt conventional drive. It gets even better for the generation two XT when you look at some of the synthetic tests like the IOMeter server profiles. This benefits boot times and any o ther activity on the computer that frequently requires a limited always-available data cache.


Caches are pretty simple to understand. However, it at least gives a good starting point. Taken to the extreme, it’ll eventually mean that doubling the sequential performace of a hard drive will 7750 in virtually no impact in overall performance. Writes are only made to the hard drive platters.

Its design makes it possible to create a GB partition for Windows while still leaving more than enough space for a second operating system. A more intensive boot run exposed the difference between the two drives. Apart from laptop and mobile applications, the Momentus works well for high-performance gaming computers and multimedia editing workstations.

For those craving performance and capacity though, the price may not matter.

Seagate Momentus XT GB Review | – Storage Reviews

When it comes down to the circuity behind the Momentus XT GB and the older GB model before it, it really is mmomentus impressive at how Seagate can take a standard notebook hard drive and make it a hybrid storage device with a simple PCB swap. When momentis flip it over it keeps the same look, hiding its hybrid secrets on the inner-facing side of the circuit board. Beginners Guides Cases and Access.
