I purchased 1 Toshiba canvio basics 1 Tb Hard disk from amazon.in 6 months ago, and guys it is really awesome the data transfer rate rages upto. 30 to 35 mbps, its very light weight, easy to handle and very good outer material for grip hard disk and there is no heating issue with the drive .
Its design is very slim and compact so you can fit it in you pocket easily and you need to know it also support previous operating system like xp, windos 7, windows vista etc.
If I talk about the price I purchase in an running offer at rupees 3790 and this is the best price for any other brand 1 Tb hard disk .
I am using continuously for several hours but I found there is no issue with the drive.
I would like but I recommend wd ultra if you need more speed transfer rate.
