Need help about HD upgrade/ external HD

[aigle]

I am planning to possibly upgrade internal HD of my laptop, Toshiba satellite M70. It,s 40 GB 5600 RMP SATA HD. I have few Qs:

1- Can I put 180 or 250 GB HD with 7200 RMP. Will increased speed will give me any performance gain?

2- Is it possible to put the old 40 GB HD in an external case and to use it as an external storage. Can e-SATA be an option here.

3- Lastly, I might just buy an external HD of 180 or 250 GB. Does Seagate has an external HD ( in small size, 2.5 inch that doesn,t need separate power supply) with e-SATA and USB support?

Thanks

1 - yes it will increase the performance.
2 - It is possible. why e-sata? If you only need it as an external storage, usb should be fine.
3 - Personally I prefer Lacie (uses samsung and toshiba hard disks) and toshiba 2.5'' external disks. Both provide an extra usb cable (for extra power supply).

Thanks, e-SATA is much faster i think.

Yes, performance will increase but it will use more battery power and generate more heat. It may even be noisier.
Putting it in an external case is easy enough, e-sata is only an option if your laptop has an e-sata interface. If not you'd have to look at regular usb or firewire perhaps.
Personally i haven't seen a self powered e-sata portable hard drive but i'm sure someone makes them.
