See reviews how fast this drive will blow your old one away, and far away:
The Hitachi Travelstar 7K200 is a 9.5mm high, 7200 RPM, 2.5-inch mobile hard disk drive.The Travelstar 7K200 is the 29th generation addition of a long heritage of Travelstar mobile drives.
Designed with combined technology including;Antiferromagnetically-coupled (AFC)technology,Fluid Dynamic Bearing (FDB)motor technology,Giant Magnetoresistive (GMR)heads,load/unload head technology,Enhanced Adaptive Battery Life Extender TM (ABLE) 3.0 and an SATA interface provides for a cutting-edge design.The Travelstar 7K100 pushes performance,capacity,power management,and exceptional quietness to provide a quality,high-performance mobile hard disk drive for today Æs demanding notebook and beyond systems.
New Areal Density Technology Advancements
Antiferromagnetically-coupled (AFC) media technology is incorporated into the Travelstar 7K200 to achieve an areal density of up to 50Gbits/sq.inch to be written on each disk.This feat is achieved by adding another layer or ôpixie dust ö -or essentially an additional layer of ruthenium/magnetic layer to create a five-layer sandwich called laminated ôpixie-dust ö.These additional layers bring even higher thermal stability to the media,allowing data recording at ultra-high densities while continuing to maintain data-integrity.
One of the key contributors to achieving demanding areal density requirements has been the reduction of the size of the slider by 3x,and the mass of the slider by over 30x (from 1980 -2007).Introducing the industry-leading Femto Slider in the Travelstar 7K200,a reduced slider in both size and mass reduction.Hitachi GST is the first drive maker to incorporate the new Femto slider product in its hard disk drives.
Implementing the new Femto Slider has resulted in;improved shock resistance, reduced power consumption and improved disk storage capacity.The reduced slider size improves the response of the slider to disk waviness,thus reducing the flying height variation of the slider in the disk drive.These advantages coupled with an integrated slider-suspension design,have been instrumental to achieving a 10x reduction in flying height over this same period.
Performance and reliability The Hitachi Travelstar 7K200 series of hard disk drives utilizes proven storage technologies such as TrueTrack Servo,Drive Fitness Test TM (DFT),Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.)to help maintain high-performance and fast seek times at high environment temperatures.

"We finally got our hands on a Western Digital Scorpio (WD2500BEVS) 250GB 5400rpm notebook drive (courtesy of Wiebetech). Many of you are wondering how it compares to the Seagate Momentus 7200.2 160GB 7200rpm notebook drive optional on the newest MacBook Pro and the new Hitachi Travelstar 7K200 200GB 7200rpm notebook drive. For power users, these are the three notebook drives of the greatest interest.
We tested them using the SATA, FireWire 800, and USB 2.0 interfaces. SpeedTools QuickBench 4.01 was used. For "large sustained" test, we averaged the results for 5 runs with 60MB, 70MB, 80MB, 90MB, and 100MB block sizes (Extended Test). For the "small random" test, we averaged the results for 5 runs of 64K, 128K, 256K, 512K, and 1024K block sizes (Standard Test).
Test "mule" was the 17" MacBook Pro 2.4GHz "Santa Rosa" with 4GB of RAM.
LEGEND FOR GRAPHS
200G 7K = Hitachi Travelstar 7K200 200GB 7200rpm SATA notebook drive
160G 7K = Seagate Momentus 7200.2 160GB 7200rpm SATA notebook drive
250G 5K = Western Digital Scorpio (WD2500BEVS) 250GB 5400rpm notebook drive
The Hitachi 7K200 is still the speediest notebook drive we've tested to date.
The WD Scorpio 5K drive was nipping at the heels of the Seagate Momentus 7K drive on large sustained transfers but fell back when doing small random transfers. The 200GB Hitachi 7K drive is the best compromise between speed and space.We must warn you that the newest, fastest drives use more battery power. We'll report on those specifics in a subsequent article -- but suffice to say, "You can't have it both ways."
Notice how slow all three drives run when connected to the USB 2.0 port. "
If you use USB with this drive, you get the convenience, but sacrificed the power of the drive.
Use my SATA 2nd Bay Caddy if you have IBM/Lonovo Thinkpad, or Dell notebooks, check my store for the wonderful little caddy, which will give you both convenience and power!!
