Seagate Momentus XT Solid State Hybrid Preview

Article Index:   

Our next series of Vantage tests will stress the write performance. Applications like video editing, streaming and recording are not what we would call a strong suit for the average SSD, due to their high mix of random write transactions.  We should also note that it's not so much a weakness of the memory itself, but rather the interface and control algorithms that deal with inherent erase block latency of MLC NAND flash.  SSD manufacturers are getting better at this, as is evidenced by our results below...

Futuremark's PCMark Vantage


The trend continued in the remainder of the PCMark Vantage tests. On the first run of the benchmark, the Seagate Momentus XT performed surprisingly well. By the third run though, performace had increased dramatically and approached the level of the true SSD.

We should also point out that we ran this test numerous times, and after the third run, the additional performance increases stopped, which is to say Run 4 performed like Run 3. The screenshots of the actual Vantage performance summaries are available in the image gallery at the bottom of the page for those that would like to see the progression from Run 1 through Run 4.

Any insight on boot time\resume\etc speed with Windows 7?  Supposedly Windows 7 was designed to work more efficiently with hybrid drives.  Supposedly.

The problem with boot testing and Windows 7 is that Windows also optimizes for faster boot times, over time. During initial testing it was impossible to tell whether it was specifically Windows or the Momentus that was actually improving the boot time. And the optimization starts immediately. If there was a way to disable the integrated flash, restart Windows X number of times over the course of a few days. Then enable the flash and check for boot time improvements, we could give some hard data. But as it is, it's difficult to say how much the adaptive memory helps with boot times.

If you look at the Vantage test results, however, the Vista startup benchmark shows that there would be boot time improvements thanks to the Momentus' adaptive memory.

It would be interesting to see how this drive compares to a similar hard drive paired with 4GB of fast flash (SDHC, class 10, etc.) and Microsoft's ReadyBoost under Win 7!

@Xylo - Readyboost has shown to provide little to no real-world performance benefit. A standard HD paired to some flash memory using Readyboost wouldn't compete with the Momentus XT's adaptive memory technique.

I don't know. I would of liked it if they used the SSD more, made it 10,000 RPM, increased the capacity and if the HD would of used SATA 6GB's. Otherwise it's a good hard drive, just not one people would like to put in their gaming systems.

I like the performance of it. The prices are manageable too. This may be something worth considering until SSD prices come down out of the Stratosphere.
