Which hard disk in Dell tudio17 and XPS1530?

[adithyagenius]

My friend is planning to buy a dell notebook pc. Does anyone know which hard disk is given when 250gb (default option) and 200GB 7200 rpm harddisks are chosen. Some companies like toshiba don't make good 7200rpm hdd. They don't provide any real speed advantage. If dell is providing toshiba 7200 rpm, my friend can save money by not buying the 7200 rpm upgrade. I know that for 320gb option in Dell Studio 17, toshiba hdd is provided. I am looking for seagate momentus or wd. Please respond if any of you know. I want to know for XPS 1530 too.
If you own one of the two laptops, please check the product no in device manager and post.I will figure out the series and speed etc.

I guess u can ask Dell Customer Care for that, and in fact demand them to put the brand of ur choice.
