Pros

larger capacities than SSD drives - allows you to carry around your music collection, larger applications and high definition media files

2 agree

ideal for laptop users who require storage and speed and only have a single drive bay

2 agree

affordable alternative to pure SSD drives

2 agree

way faster at everyday tasks than a standard disk drive - boots and accesses applications within seconds of a pure SSD drive

2 agree

intelligently stores users most accessed data on 4GB of SLC flash - can shut the disk down if users are only accessing what is on the flash

2 agree

first working hybrid drive - combines the storage of mechanical spinning platter drives with the speed of solid state flash ones

2 agree

learns quickly - tasks are usually faster by the second time you perform them

2 agree

hides hybrid nature completely from BIOS and OS - no software issues to worry about for installation (though OS should support TRIM for hi-performance operation)

Cons

no write cache - SSD buffer is for reads only

2 agree

defragmenting sets the drives flash cache back - makes the drive have to re-learn about your most often accessed data

2 agree

uses a considerable amount of power - double that of an SSD, slightly more than the average mechanical drive

2 agree

4GB isn't really enough to store very much - will have the disk active when using most used applications

The Momentus XT is a 2.5-inch laptop drive combining traditional 7200 RPM disk platters with 4GB of SLC NAND flash memory. As a hybrid product, the Momentus XT competes with SSD drives, offering comparable speeds with higher storage capacities. The hybrid nature of this drive is used in conjunction with Seagate’s Adaptive Memory technology to keep frequently accessed data cached, equaling better performance through faster read times. There is also 32MB of drive-level cache, which is essential to this drive’s level of performance. The consensus amongst expert reviewers indicates that while this drive does not reach full SSD speeds, it generally outperforms most standard 7200 RPM drives. Seagate recommends this product for performance and gaming laptops, however anyone looking for faster drive performance without sacrificing overall storage capacity should find the Momentus XT to be a useful upgrade. Capacities include 500GB, 320GB and 250GB models.
