OCZ Agility 3 60 GB Desktop, Laptop SATA Internal Solid State Drive (SSD) (AGT3-25SAT3-60G)  (Interface: SATA, Form Factor: 2.5 Inch)

I upgraded my DELL 1545 laptop having sata 2.0 (3Gbps) connector, which took only 5 mins. Believe me SSD is best !!! I wish Flipkart soon start selling PCI based SSD Cards.

Few things to consider :
(1) Don't Defrag SSD, also run WEI as soon as OS is installed this should stop scheduled Defragmentation, better check manually
(2) Don't jump on benchmarking as soon as installed it
(3) never full the SSD , have at least 5% space left to improve performance
(4) Keep backup of important data
(5) ...

i bought it from flipkart today and replaced it with my toshiba hdd 320 gb for my sony vaio vpceh35en laptop.. (for information sake let me say that intel mobile chipset/motherboard HM65 supports 6 GB\Second speed and does have SATA 3)..just unscrew the laptop hard disk covering and remove the hard disk from its steel cage and replace it with this ssd...works without any problems..windows installation is very much faster and so is the startup and shut down..windows base score is 7.9 for the ...

This is a must have component. Most people find it weird that this costs so much for such a small disk size. But SSD's are much faster than the spinning ones. What this means is faster boot speeds and quicker program startups.

The current bottleneck in modern computers is the disk IO speed. I have two disks, one 500GB 7200RPM disk and this one. Here's a quick benchmark comparing the two:
