Summary: I bought this 21 days ago from flipkart, delivery was good. I've upgraded my system (4 years old Lenovo 3000 y410 laptop) easily with this SSD. After upgrade, indeed speed changes in system. Dont expect it is too fast. but it will almost double the speed then your previous hdd. My laptop with Windows 8 boot time was around 1 min. now it is booting in 15-25 sec. I think it is slightly expensive but worth the speed.
Summary: Hey guys Samsung is the only company which manufactures each and every part of their ssd's including the firmware.This drive is sort of an upgrade to its 830 drive.this runs on a samsung designed 3 core controller which is better than the sandforce and performs equivalent or better than indilinx controller.
