internal harddisk

Hi bro, just a question which company's internal hard disk is good and very stable. I have been using seagate for long time, i believe company's reputation has gone.I replaced my 320 gb hdd for several times , even though company gives 5 year warranty but no use.I was replacing my hdd continually and so many times data losses,recently just a weak back my hdd has come from replacement, just with in 5days of time again status of hdd has degraded. I'm really fed off with this hdd(seagate) prior to this same case with 250 gb. So which internal hdd is best(cost effective).

And please let me know that any incompatibility of my system is causing frequent hard-drive failure , I will provide with full specifications of my system. Myself i built this system.

Core2duo E7300
GA-Ep43(gigabyte mobo[no display board])
4gb(2+2) 667mhz
320gb seagate hdd ( 2008 june)
d-link wireless desktop adapter
Nvidia 9800gt of 1gb DDR-3
LgDVDrom
I-ball gaming cabinet with 600watt smps.

Cooling-additional 4 powerful fans and default 3 fans

If it's a computer I advice getting an external hard drive, you can get 1TB for like $40, and internally I'd go with Acer, of all the Acer computers I own, none of the hardware has ever failed. Yet, with HP, the HDD, mintor, CPU, fan, and some other stuff, all broke in less than a year.

 

which company's hdd is most reliable for computing(preventing data loss) even though provides with less warranty . I believe running windows from external hdd is very slow. any suggestion . Do you find any incompatibility of above system configuration?
