OCZ Vertex 4 128 GB SSD Internal Hard Drive (VTX4-25SAT3-128G)  (Interface: SATA, Form Factor: 2.5 inch)

By far the best i have ever used, its beast bought it from some where else. Made my acer a Monster but am stuck with this 128gb variant. Would request Flipkart to make 512gb variant asap, and i can assure will be the first one to buy that.

As i cant find any 512gb variant please make some avilable.

My SSD research till now.

1. Vertex 4 : All performance.
2. Samsung 830/840 series : Stable with high performance.
3. Crucial M4: Stable, good read speed, write speed is decent good for SATA 2 d...

Bought one of these last month, did a Win 7 clean install & optimized settings for SSD & all drivers & updates in about 2 hours. Everything went smoothly, and so far the speed looks as good as advertised. The firmware was up to date out of the box (v 1.5). My WEI(Windows Experience Index) for primary disk drive is 7.9! Using it since one month and not a single BSOD! I will highly recommend this drive if you have the budget. No other brand SSD can compete with this one.
