Want to Buy ITB internal HD

Dear All I want to purchase a 1TB internal hard disk. please suggest me the best available.I have checked WD caviar Blue is not available locally even on Glaxy and CZone. WD caviar Black is expensive. Please suggest.

Go for Seagate.

WD is tough and deserves the relative high price.

Edited

I realised he wrote internal HD. I had written about external HD. :)

AHS:I have checked, WD caviar Blue is not available locally even on Glaxy and CZone

Has someone checked the performance of Seagate and is this ok (SEAGATE 1000GB 3.5" HDD 32MB Cache (ST-31000528AS)available from galaxy for Rs 5600.

or this one from Czone Barracuda® 1.0 TB SATA II 3.5" ST31000524AS 32MB / 7200 and what is difference.Also there is a huge difference in the price of Galaxy and Vmart. Vmart is selling the same drive for Rs7750 and Galaxy for Rs5600 why?

WD black is a freakin' joke in itself. Their 1TB black model is 9,000+. I'd rather spend that much on a much much faster SSD instead. To be perfectly honest, its completely overrated, except for a mere 3 ms reduction in seek time. Seagate is a much better alternative, both price & performance wise.

Purchased Seagate barracuda 7200.12 ITB ST31000524AS. The Windows experience index shows the points 5.9 for hard drive. Is it Ok?
