Seagate Momentus XT 750GB Hybrid Drive

10 thumbs up

Performance Summary: The Seagate Momentus XT 750GB drive performed relatively well throughout our battery of tests. When its solid state cache comes into play, the Momentus XT is clearly faster than a standard hard drive and in some instances offers true “SSD-like” performance. The updated Momentus XT is also clearly faster than the first-gen drive due to its faster HD, increased solid-state cache and tweaked adaptive memory algorithms that react more quickly than the original’s. In comparison to other hybrid solutions, the Momentus XT competes favorably, but Intel’s Smart Response technology or options like the RevoDrive Hybrid are ultimately faster—sometimes much faster. Finally, compared to a standalone SSD, the Momentus XT trails in every facet of performance.


The Seagate Momentus XT

When we first took a look at the original Momentus XT mid-last year, we stated in our conclusion that, “While the Seagate Momentus XT doesn't clearly dominate all standard hard drives across every type of usage model, Seagate's hybrid implementation seems to address its intended markets quite well.” That statement is also true today, and the updated drive is definitely superior to the original in virtually every way. However, the storage landscape has changed dramatically since the original drive was released.

When the first Momentus XT hit the scene, it was offered for a cost of about $.31 per GB ($156 for the 500GB model). This new 750GB Momentus XT, despite offering a faster interface speed, double the amount of SLC NAND flash (4GB vs. 8GB), and tweaked adaptive memory algorithms, will debut with an identical cost per GB; the drive will sell for about $.31 per GB or $245 for the 750GB model. At the time of the original Momentus XT’s release though, sought-after SSDs were commanding upwards of $3.00 per GB. But today a good SSD can be had in the $1.20 to $1.75 per GB price range. And while hard drive prices have skyrocketed due to the tragic flooding in Thailand, it’s still possible to pick up a 500GB to 750GB, 7200RPM drive and a 120GB SATA III SSD for only slightly more than the cost of a Momentus XT. If you’ve got the right motherboard, using Intel’s Smart Response Technology can actually be cheaper when pairing a similar sized HD to a 20-40GB SSD cache. Using a standalone SSD for the boot volume and a hard drive for bulk storage will result in better performance, but is perhaps less elegant due to the need to manage both volumes, whereas a single hybrid solution is more seamless for the end-user. Regardless, the clear cost advantage the original drive had at launch has somewhat vanished.

That said, for users that can’t afford a larger capacity SSD and are limited to only a single drive configuration, like notebook or some HTPC users, for example, the Momentus XT can be a great fit. You’ll get a good amount of storage space and SSD-like performance in a single drive, with any OS and no special software or drivers to deal with.

  • Decent Value
  • Good Performance
  • SSD-Like Performance, HD-Like Price
  • OS Independent

  • Limited by performance of the HD when solid state cache not used
  • Outperformed by other hybrid solutions

Great review Marco, glad to see Seagate is keeping up with these drives. I have the 500gig momentus xt in my wife's laptop. I love it, speedy with more room than an ssd. We really only use the laptop for basic tasks(internet, office, music/movies) so this drive is perfect, and I would recommend it to anyone who is in the market for space and wants that little extra kick in the pants.

That being said I agree with you Marco, for a desktop there are certainly better options but for a laptop I think it works really well.

The Seagate Momentus XT was a revolutionary drive at it's time... It was the first hybrid drive that was adorable and in the face of all the competition, it carved a niche for itself.

Today, not so much...

I mean it's nice that Seagate is keeping up by adding a more efficient algorithm and a SATA 6Gbs interact but let's be honest, there are newer SSD's and hybrid drives out there that are more powerful and more efficient then the original Momentus and more surprisingly the newest Momentus. Again, it was the product of it's time and while it may serve some people the same way as the original product did, I think it's about time they took it back to the drawing board.

Still, good review Marco!

Still good to see that Seagate developed the Momentus Xt series a bit more and for a single HD disk with a bit of storage& is no slouch for a single -drive set-up. very nice to see that the $.31 per GB cost is not to shabby either for the increased boot/ and speed performance upgrade.Be interested to see what the price of a 500GB version like the one Drake mentioned would be to recommend as well.By the time the HD prices get back to normal in a bit be interesting to see what some decent 250GB SSD drives will be going 4 for as well.

Pretty cool... I don't think this will last all that long though.

The price of SSD's will be going down quickly I think, especially the first generation SSD's that are ~250mbps

Recently bought a 160gb ssd for ~$130... which is a great price.

A nice evolution but honestly, nothing new. This is still a 1st gen hybrid drive

If this were a 2nd gen hybrid, I'd expect at least 16-32GB of flash per terabyte, and it wouldn't be read-only either.

cannot wait for these guys to come up with 1TB of those puppies

I love the idea of this drive, even though im not a huge Seagate fan, ive been pretty curious about them and i wish i could win one rather than have to go buy one.I really like the idea of SSD's too, but im just as leary of those too. I hate venturing into unsure tech and being totally dissapointed with it, and worst of all, being stuck with it and out the cash!!

I remember the flood in Singapore or Malaysia causes the price to rise in HDD

$200~ for a WD Caviar Black 1TB pretty sad :_(

That is a sick set of stats for a product fitted to preform, it was created with i7 in mind and the best of the best to be its companions, i am not a little bit irked at the thought of not having one but then again i do love my hardware. it would be quite a great experience to take a top of the line hardware set and connect with this hard drive the only issue would be finding something it couldn't do.

I had one of the '1st' gen 500Gb hybrid drives. For all intents and purposes it didn't feel any faster than the regular drive it replaced. Now that was in a notebook and its possible the IO was gimped in a similar way that intel does with its netbook chipsets, but you'd still expect a bit faster performance right?

With SSDs continuing to drop in price (though not anywhere near as fast as I'd like) and offering absolutely noticeable performance improvements over spindle based drives, I'm not really sure there is a big enough market for these hybrid devices. Perhaps 5-8 years ago when they were first proposed they would have been amazing, but now.... meh

For me, its a case of too little too late.

Seagate and WD have to get off their backsides and start throwing some big dollars at creating their own lines of true SSDs instead of letting the small fish (corsair, OCZ, etc etc) eat their dinner.
