Seagate Momentus XT Solid State Hybrid Preview

CrystalDiskMark is another synthetic test we've started looking at that evaluates both sequential as well as random small and large file transfers.  It does a nice job of providing a quick look at best and worst case scenarios with SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.

CrystalDiskMark tells a similar story to ATTO.  Here, the Momentus XT finishes in between the Scorpio Blue and Barracuda once again, but well behind the SSD. In a strict comparison between WD's fastest mobile HD though, despite the fact that CrystalDiskMark does not exploit the Momentus XT's adaptive memory technology, the Momentus XT puts up significantly better numbers in every workload.

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.
