Seagate and Western Digital are the giants in the hard disk industry.However,Seagate recently has to face a lot of noises about the firmware issues which has caused the company lose some market shares.Well,Seagate is trying the best to maintain the reputation by introducing new products,including the fastest 2.5 inch 7200 RPM hard disk-Seagate Momentus XT.
Basically,it is a 7200RPM hard disk with 32MB cache and 4GB SLC NAND solid state memory.Seagate applies Adaptive Memory™ technology to utilize the solid state memory when it’s necessary.The performance will be improved by normal usages and also boost the boot speed.
I did some simple tests using HD Tune.Here are the snapshots.

The pics show the read speed,the health of the disk and I/O speed.You will find the figures maybe are quite similar with other 2.5 inch 7200RPM hard disks because the SSM can’t be utilized in such kinds of tests and so no enhancements for the overall figures.In fact,you can see the real differences between Seagate Momentus 7200.4 conventional hard dish and this Seagate Momentus XT hybrid hard disk.
The price of this hard disk is almost 1.5 times than the normal 500GB 2.5 inch 7200RPM hard disk,but if you always eager to save your time on opening files or loading some programs,this new product from Seagate will give what you want for your laptop.I enjoy it! ![]()
