Transcend storejet 640 GB hard disk is ver much faster in copying the data from my lappy as well as pc.
I am using transcend storejet 640 Gb hard disk for 3 years and till now my hard disk is performing perfectly there was no mistake in my heart is still now it gives around 60 to 70 MB per second speed for copying data from PC
After sales support is also amazing actually I want an extra code because my original code was misplaced so when I got to the service centre they really was for kind and they really helped me in so pleased manner.
So I am really happy with the performance of transcend harddisk and 650 GB storage is really enough for backup of our data.
