Hello. Can someone please give me some advice. I am choosing between the Western Digital Caviar SE16 WD2500KS 250GB and the Seagate Barracuda 7200.9 ST3250824AS 250GB internal hard drives for my Dell 9100. The WD has 16MB cache vs 8MB for the SG and an 8.9ms seek vs 11msec for the seagate. they are both SATA II at 300MB/sec transfer rates. The catch is the seagate warranty is 5 years vs 3 years for Western digital. the price is the same. Which is better??? performance?? reliability? What to do???? THANKS!!
