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.

ST95005620AS(1)ST95005620AS(2)ST95005620AS(3)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! 微笑

Disassemble and clean up my laptop

I owned my Lenovo 3000 N100 laptop in September 2006.Till now,it has been 2 years and 3 months.I never did any cleanup work during the years.So I thought there should be full of dusk inside.Is that real?Let’s check it out:

A back picture

There are mainly three parts of modules on the back and I opened them one by one.

Remove the top,seeing the fan,heat pipe and CPU socket. Here it contains a fan which releases the heat from the whole body of machine.Do you see the metallic heat pipe?The processor is just under it.

It's another module,installed with two pieces of RAM.

Originally there was only 1G RAM installed.But as previously it was running Windows Vista.Obviously it raised a bottleneck so that I bought another 1G RAM in order to give out an optimum performance of the system.

The final partThe 2.5 inch hard disk and WIFI module are put into the same unit.The SATA hard disk was made by Hitachi.I’m considering to buy a new one with a greater disk size as currently this one only has 80G.

After clean-upIn fact I didn’t do much on clean-up because it still could be considered as tidy.How miraculous it is!

 

All right!Could anyone tell me which brand/model of hard disk could work with low heat and high performance?Thanks a lot.

P.S:I feel that Lenovo has a much solid quality compared to HP.
