Seagate Momentus XT 750GB Solid State Hybrid Drive Review – SSD Performance With HDD Capacity

ATTO DISK BENCHMARKS

The ATTO Disk Benchmark performance measurement tool measures total storage system performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously:

ATTO was set to a length of 256Mb transfer from 0.5Kb to 8192Kb. The results are the same as we have been seeing. NAND is just not utilized, not even in the ATTO benchmark. Take note that while the Momentus XT shows a sizeable improvement over the first generation Momentus (as it has shown in other benchmarks as well), it is essentially on par with the Western Digital Scorpio Black, again due to the fact that the SSD segment of the Momentus XT is not exercised

CRYSTAL DISKMARK

CrystalDiskMark is a small benchmark utility for hard drives (as well as flash drives) that enables rapid measurements of sequential and random read/write speeds:

Testing Adaptive Memory Technology requires running the same test about 10+ times in order to randomize the data. Even after all of those trials, the Momentus XT could not produce the same results as an SSD would.

  1. The m4 ssd is one of the most reliable ssd out there. the 64 gig version can be purchased now for $109 free shipping no tax from newegg add a terabyte hd for mass storage and you get a faster, higher capacity and cheaper solution!
    the 128 gig version is $199

    • You can’t fit that configuration in most laptops. This is a 2.5inch drive perfect for laptops. If space isn’t an issue you could even look at a RAID system.

      I have used the 500Gb XT for a year now and am impressed. Not just with the real world usage but in particular with Seagates commitment to sorting out the early issues with this drive. They are actually listening to these reviews taking onboard the criticism and working with its customers to progress the technology further and releasing regular updates.

  2. I think this is one of those situations where there has to be a paradigm shift in the priorities and what is being measured. A drive like this was not made to run benchmarks, it was made to learn and adapt to the usage scenario at hand. The fact that most benchmarks showed a small improvement, or no improvement at all, but the author was still raving about the product, is a testament to that. I think benchmarking the loading times of a suite of programs over consecutive runs would be a much better indicator of what this drive brings to the table. In that scenario this will probably mean the best of both HDD and SSD worlds.

    Thank you for this review and the many other informative articles. 🙂

    • Thanks, and thanks a lot for the informative post!

      While I didn’t push the fact, I was hoping readers such as yourself would figure out that there aren’t really any benchmarks that can effectively test the Momentus. I provided all of the benchmark tests one sees with essentially every drive, but they just don’t work due to the adaptive properties of the Momentus.

      Again, thank you for the insight 🙂

  3. “The SSD bond really shows here, as traditional hard drives do not use firmware.”

    Somebody needs to tell Seagate, they are distributing firmware updates to all those drives that don’t even USE firmware.

  4. Anyone notice that from the Boot Time Comparison chart that Quicktime is rubbish no matter what system you have!

  5. Thanks! A really top review. Just confirms what I thought though; that these hybrid drives are largely pointless, or at least that they’ll have a very limited lifespan. I can’t see how SSDs can cost more to produce that mechanical drives, over the long term there’s no argument for having one of these drives. As it is they still can’t compete with SSDs, but whether they compete with a setup like I have which is 128GB SSD for O/S with a 1TB IDE for storing data, I’m still largely unconvinced, particularly given their price!

  6. Different model, but I have had the Momentus XT 500GB for about a year now and it got painfully slow after six months making new slowness records each month.. Maybe it’s just me getting partially spoiled by the SSD part, but still.. Sometimes I think I must be infected with everything bad crawling the web, bots, trojans and all sort of viruses hogging my system, but I am afraid it’s just a growing feeling of slowness. When the SSD part works it’s great, but it’s too small, only 4GB on this model, and when it switch to HDD it’s horribly slow. I think all that this drive and other hybrids really do is to wet your appetite for a total HDD-free SSD solution.. Which kind of explains why I am lurking around here; I think it’s time to go fully SSD.

  7. I will be first in line to buy 2-4 Hybrid HDD/SSD 2.5″ drives when there comes a version with a combination of 32-64GB SLC NAND Flash + 1TB 7200RPM (1TB platter, single platter) HDD + 64GB ECC DRAM. I am all for using 2.5″ form-factor drives in my desktop, as I can fit a lot more drives in a relatively limited space, and to be able to have MORE drives without sacrificing speed but rather enhancing it, is a dream come true!

    WD just announced a 2.5″ Drive with 64GB NAND that looks to be a “one up” of Seagate’s Momentus XT, and if they really pan out well, I will be buying at least two to start with and throwing them into a RAID0 array. Although I have a 256GB Samsung 830 SSD, and will soon have a second, I want large-capacity storage for uncompressed audio files (tens of thousands) and 1080p video files, not to mention games. 2-4x 1TB single-platter 2.5″ hybrid drives with 32-64GB SLC NAND each would make THE fastest RAID array that actually uses spinning disks.
    We’re talking 64-128GB/128-256GB of Solid State Storage with 2-4 Terabytes of disk storage! Combined with good detection algorithms, I don’t see why it couldn’t perform so close to actual SSD’s as to be imperceptible!
