Final Words
Seagate's Momentus XT should become the standard hard drive in any notebook shipped. The biggest problem I have with using any brand new machine, regardless of how fast it is, is that it never feels fast because it usually has a HDD and not an SSD. While the Momentus XT isn't quite as fast as an SSD, it's a significant improvement over the mechanical drives found in notebooks today.
In many cases the Momentus XT performs like a VelociRaptor, but in a lower power, quieter package. The impact of adding just a small amount of SLC NAND is tremendous. I wonder what kept Western Digital from sticking some NAND on its VelociRaptor instead of giving us the lackluster upgrade we got earlier this year.
The potential for hybrid drives continues to be huge, what Seagate has shown here is that with a minimal amount of NAND you can achieve some tremendous performance gains. There's no reason for any performance oriented mechanical drive to ship without at least some small amount of NAND on board. There's also much room for Seagate to innovate. We could see drives with more NAND or truly hybrid drives that provide read and write caching in NAND.
Compared standard 2.5" drives, the Momentus XT will set you back an additional $50 - 90 depending on the capacity point. The added cost is absolutely worth it. It's still a lot cheaper than an SSD since we're in the sub-$0.31 per GB area while SSDs sell in the range of $2 - $4 per GB.
If you're not going to buy an SSD for your notebook, then definitely go for the Momentus XT. I'd almost go as far as to say it's a great option for desktop users but unless you're on a budget you're probably better served by a small SSD + 3.5" drive on the desktop.

As I said: all files up to 256k (512B - 256k) can be stored on the 4GB Module. I don't think that the firmware moves bigger files onto the NAND, because it is a waste of space and a waste of performance gain (there is nearly no gain).Just check it with JDiskReport for example. On my system (windows 7 x64, many programs, some games on partition C, install is ~8 months old) all files from 0-256k together make up about 3GB of space.
So again: 4GB should be enough for most users to store EVERY smaller file (256k is rather big).

If you want to speed up Windows boot - you do not need neither SSD nor hybrid HDD. Just install and configure Boot Cooler (www.bootcooler.com). It is free. But it is beta. And it will not accelerate application launches after Windows boot.cauchy2k - Tuesday, May 25, 2010 - link
I think SF-1200 SSDs controller (with its new free space tweak) are affordable compared to other SSDs prices,Intel which is one of the cheapest and better ones cost 225 for 80 GB, and this one cost 200 for 60 GB.SF-1200 SSDs are just 18,4% more expensive than intel's alternative.Maaniu - Tuesday, May 25, 2010 - link
If they put a somthing that works like a real ssd with a hdd i think then we will see real performance.Thanks.
P.s i have been checking out your site 4 sometime now you totally satisfy my tech cravings.

Interesting article, but I still have no idea of my HP Mini netbook (2 GB RAM) would benefit at all from this drive. Considering the CPU is a *huge* bottleneck, I just wonder if anything would feel snappier with this drive? For now, I must keep searching....ash9 - Tuesday, May 25, 2010 - link
This product is great for laptops, an added 2/3/ hours of added usage with a real graphics card is worth the extra cash.asH

Reading web pages saves lot of small files to disk.I would like to know if a SSD helps loading web pages. If true, this also would hurt this hybrid kind of drive, because maybe lots of small files used only once could be stored in the flash memory.

It definitely does, but I cannot provide numbers.I had a Hitachi 5400rpm in my laptop (~2 years old). I changed to a UltraDrive ME (GX) about 16 months ago. And the pages load definitely faster. I always had a feeling, that the HDD limited somehow web page loading, because I really heard how stressful this really is to a slow HDD.
Again, no numbers here, but they load definitely faster if you used a slow/old HDD before (don't think that there is any difference with fast 7200rpm HDDs).

sounds like a nice project for bored engineers, but I personally hate hybrid anything. its there to just delay the inevitable and/or milk the old as long as possible, while at best complicating the overall system and increasing potential failure points.just like cars.

And yet any step forward is better than standing still.
