Conclusion: One of the key features of the Momentus XT is the ‘Adaptive Memory Technology’ that’s basically a self-learning algorithm that notice your most used programs and stores their data on the cache. So every time you run those programs again, they will be loaded as quickly as an SSD since the data is being read directly from the 8GB NAND Flash.
Conclusion: The Momentus XT is a hybrid in the best possible sense. You get the capacity of a traditional disk, along with (some of) the speed of an SSD, without breaking the bank.
Pros: Flash memory means faster speeds. Drive adapts to your usage.
Cons: Moving parts means it’s still susceptible to damage, just like your regular drive. Speeds up boot times, but transferring files is pretty much the same as traditional drives. Higher cost-per-gigabyte.
Summary: If you want the fastest performance possible, then a full-fledged SSD such as the Samsung 830 Series ($209 for 128GB) is still the way to go. However, if you need more than 128GB of storage and can't afford to mortgage the farm for a 256GB or larger SSD, the Seagate Momentus XT is your best upgrade option.
Pros: Fast boot times, Speedy app opens, Lower cost per GB than SSDs
Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete.
Pros: All-in-one Hybrid storage solution does not require software, Outperforms PCI-Express hybrid solutions in boot and file transfers, Seagate Adaptive Memory tech buffers data for SSD responsiveness, 5-Year full Seagate product warranty, Large 750GB hybrid storage capacity, Extremely high HDD operational shock durability, Supports Native Command Queuing and SMART, SSD Failure does not effect preserved HDD data, 3rd-Generation SATA 6Gb/s compliant
Cons: Lacks comparable IOPS operational performance to SSDs, Expensive hybrid storage solution (post-facility flooding), Hard disk would benefit from 64MB DRAM buffer
