Looking over the specifications the first thing we noticed is the SSD is just 4GB and seems a little small for much of any anything. To get a better understanding of how the drive uses the 4GB SSD of the Hybrid drive, we will have to explain the architecture of the drive first. The Momentus XT has a set algorithm which dynamically updates the 4GB SSD side with most recently accessed information in order to keep the files and other pertinent data readily available to you. This algorithm is what Seagate® has patented as Adaptive Memory ™. During benchmarking the Momentus XT in the lab, we did find that running the benchmark programs a second time and third time immediately after finishing the last run the resulted in getting a better score by a point or two. This small increase in benchmark scores is like attributed to the benchmark program being loaded into the SSD segment of the drive. The SSD and the 7200RPM spindle are not seen as separate drives by PC’s BIOS or Operating system, so there is no need for any special setup of the drive. Simply install the drive in your laptop or PC workstation and load your operating system and that is it. The Momentus XT can also be used in external storage devices also and with the recent release of USB 3.0, you will be able to take advantage of the great read/write and access times.

Quick close up the Momentus XT shows us that from the outside of the drive, it looks just like any other 2.5″ SATA drive on the market today. So for being a hybrid having platters and SSD there is not increase in size.

|This is about the average result for a 5400RPM SATA drive||The Momentus shows very positive results in comparison.|
There is very little variance in the results between our Samsung SATA drive and other 5,400RPM 2.5” drives on the market, so to use that as a comparison point for the Momentus®XT we can clearly see the Momentus® XT really puts up some very positive scores.

|File system benchmark against Samsung||File system benchmark against Seagate® Momentus XT Hybrid|
The file system benchmark against both drives came out as expected with the 5,400RPM drive holding its own. Though when we ran this benchmark a second and third time the Momentus XT drive resulted with a much better score.
