This device is good but its build quality was not great even not good. I purchase this harddisk at rs.4, 099 from amazon.in
this 1.5TB harddisk has free space is 1.36GB. it device speed is good. It also support usb 3.0 and 2.0
in usb 3.0 it speed around 120MBPS( highspeed) avrage speed 70mbps to 100 mbps. in 2.0 it speed 40MBPS( high speed) .
Normal speed in usb 2.0 is 20 MBPS.
it was a good device but the thing I dont like that is the build quality.If any device have not the good quality the device was not good for me( maybe for also you) .Build Quality is matter because if the device was dropped from hand or something else the 4thousands money was totally waste cause if the drive dropped from your hand then the harddisk will corrupted afterthat the hardisk was no more.The Hardisk is made of totally plastic.it looks great but it was slepy. whatever I am shareing my own opinion. your choice that youre buying this device or not.
Pros
Low Budget
Speed is Good
Compact Device
Corns
Build Quality
Slepy Finish
That was my personal opinion after your decition and your choice what you want to do. I just told you that if build does not matter then go for it it was good device but you will need build quality then I strongly recommended you that do not go for it.
