With the whole world going green, Western Digital has offered Eco-conscious users an
alternative with the Cavier Green hard drives.
Western Digital claims that this green series of hard drives use lesser power. Also they
are supposed to run cooler. This is done, in my opinion, to remove he excess power usage due to hard drive coolers.
The Packaging:-
There is nothing different from ny other drive on the market. This comes in a silver
conductive bag with a sachet of silicon gel in it, for keeping static electricity and
moisture at bay.
Now, lets get to business. The part where it matters. The Benchmarking Tools Used:-
ATTO
PCMark Vantage x64
HD Tune Pro
Everest Disk Benchmark.
HD Tune Benchmark Results Read Benchmark:- http://img.techpowerup.org/101006/hd tune benchmark.png
The curve is sloping downward.. this is mainly due to the fact that read speed is fastest at the centre and slow at the ends.
File Benchmark:- http://img.techpowerup.org/101006/hd tune file benchmark.png
This benchmark is performed by writing and reading files to a disk.
The read speed is quite high at latter ends is quite good. It is normal for the write speed to lag. Health Info:- http://img.techpowerup.org/101006/hd tune health.png Everest Disk Benchmark:-
Read suite:- http://img.techpowerup.org/101006/everest read benchmark.png
Begin stands for areas closer to the centre,
End stands for ends closer to the ends of the disk
Middle is for anything in-between.

The results are astounding. Summary and Conclusion
With an average write speed of 70 MB/s this hard disk is pretty neat. http://img.techpowerup.org/101006/HDD idle temp comparison845.png
Temperatures at Idle is just 36C with an ambient of 30C is really prooving the point of being a ECO and COOL drive.
**Pros:-
Price is just Rs.1742 (inclusive of all taxes)
Speed is more than enough for simple storage and acceptable for some gaming.
Cons:-
NONE!**
hope you enjoyed this review. and that it was helpful.
thanks! i do proffesional. sorry i dont have a camera though.
THANKS dude!
i tried sooo hard. but i couldn’t find a blue or a black one in Kolkata!!!
i dont think so mate, check the everest results.
you know how the tracks are made on the disk right?
its just concentric circles divided by radii.
so for a single track to be read, a track will be read faster at the center(due to lower circumference) and slower at the edges(due to greater circumference). Note that the speed of rotation is a constant 7200RPM.
the speed on the disk at the centre and at the edges is different (law of mechanics)
Eg. the higher speeds in gears have an overall lower circumference since they increase the speed of the wheel at the same rpm. i.e if the rpm is kept constant, the gears increased, the circumference of the gears gets reduced, the speed at the edges increases, the wheels rotate faster.
