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


Luckily, the Momentus XT’s arrival coincided with the building of a new test bench. All of the precautions and settings were followed according to Seagate’s testing directions:


Todays benchmarks are going to be a bit…extensive…as we put the Momentus XT through the ropes with a wide variety of software to include  HDTach, HDTune, AS SSD,ATTO, Crystal DiskMark, PCMark 7, PCMark Vantage, along with true to life tests with Adobe CS5 and 7-Zip.


HD Tach is a physical performance hard drive test which utilizes a special kernel mode VXD in order to get maximum accuracy by bypassing the file system. The HD Tach sequential read test reads from areas all over the hard drive and reports an average speed. HD Tach also tests the drive’s random access time, as well as its burst speed:

With the average speed being the most important factor, there is virtually no gain in sequential read performance over the first generation Momentus, which was expected. As before, the NAND does not contribute to the results of the new Momentus XT.

HD Tune is a hard disk utility which by means of a set of simple steps checks the status of hard drives (internal, external or extractable). Apart from checking the status, the application is measures the drive’s performance, errors during scanning, and health status. HD Tune writes over the full area of a hard drive, exposing any potential drawbacks the drive may have:


The AS-SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains five synthetic and three practice tests, testing sequential read and write speeds, as well as input/output functionality and response times:

Again, not much to see here; the NAND/SSD portion of the Momentus XT has not made itself known yet, but the hard drive piece is certainly showing its ablity.

About Deepak Sharma

I am a big PC enthusiast, and avid gamer. If I'm not tinkering with parts, or reviewing products, you can be 100% certain I'll be on Steam playing something. I love learning about new tech, and teach myself as much as I can, so I can present it to every techie out there!

    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.

    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!
