Hello,

Im looking into buying a new dell desktop computer. When choosing hard drive, I have to following two options - the price is the same. Im going to use the computer as an all-round home PC:


1,5 TB Seriel ATA-harddisk (7.200 rounds./min.)

1,5 TB on two hard drives, RAID 0 Stripe (2 x 750 GB, 7.200 rounds./min.)

What should I choose? And is there any difference in speed?

More about : 750

The twin 750's will boot faster and applications will launch faster

This will double the speed of the system when working the Hard drives. Another Option is to use 3 , 500GB 7200 RPM and make it even faster. (When comparing to just 1 drive, 2 doubles your speed, as the 3rd adds an additional 50% to the two. and a 4th adds 25% a 5th adds 20% and so on) 2 hard drives are the most common when RAID 0 is set. I am building a computer with 4 7200RPM HD with only 160GB each. The only downfall is that if one of the drives fails, You lose all your information. Think of it as dealing a deck of cards to the # of drives you have evenly. So if you have 1 of the 5 drives fail, you lost 20% of all of your information. However 5 drives is 5x faster than just 1 drive. However, now you have 5 X's the chance of disk failure than just 1 drive. Pick your poison...
