This isn't the best SSD out there, and maybe its the cheapest one available on FlipKart, but still this has more power than a standard HDD.
The Ubuntu (linux) installed on it in less than 10 minutes and boots in less than 7 seconds! Thats too fast for me, as Windows 7 on 7200RPM HDD takes more than 2 minutes to load completely. This is the best HDD you can get for 3500. I didn't get any accessories like screws, SATA cable or power connectors, but its fine since I had some spares.

But, if you...

Like the earlier reviewer said, it's not the best SSD on market. It's cheap and it can be used to install OS and programs. Total usable size is 27~28GB and it can be sufficient for Win XP or Linux (Ubuntu, Mint, etc). I've installed Win 7 x64 on it. But have another drive for programs. You can disable certain features like hibernate, etc to save SSD space.
There is huge difference in performance compared to HDD. So people looking for a faster computer by spending less - this is the deal for you.

Best device for School(institutions), Net Cafe's and offices where storage is not in high priority,

Excellent performance,boots Windows in just seconds
could find noticeable response in drive exploring, booting & restarting

Cost effect & longer run time as compared to other brands
Must Buy!

As the first reviewer said, you get what you paid for.

I was looking for the cheapest hard drive. It was supposed to go into a system which will be used for just office applications and space is not a major issue.

Have installed XP and dont see any major difference between a decent HDD. But was cheap and serves the purpose.
