If you have the necessary bays, cooling, power supplies, etc etc. It really doesn't matter. If you're planning to do a RAID setup then (depending on the exact setup) you may indeed want to go with three 2TB harddrives. However if you're just using them for typical storage then I'd recommend you go with two 3TB drives because it'll save space. Your case doesn't need to be the size of a tank. Like I said, it all depends on what you're trying to do and what you have to work with. |

In my experience with HDDs, I would go with the two bigger drives. More physical devices need more power to run and more power being drawn off the power supply could have negative effects on the rest of your system. However, like Zbob750 said, if you have the means to draw the power and bays to house the drives, then it really truthfully doesn't matter. But more times than not, its best to go with the least amount of devices as possible. In this case, the least amount of HDDs as possible to still obtain the same space. |

What is a raid configuration Here is an idea of what raid is from a wiki that I have found. http://en.wikipedia.org/wiki/RAID Depending on your set-up of the computer. Some motherboards you can configure Sata drives as a raid system. Meaning if you have two 2 Terabyte hard drives Raid 1. Means if one of the two drives should fail. you will not loose any information. While Raid 0 if either drive fails your data is pooched. So it will depend if your computer does have the set-up for this. Some motherboards do include this and others do not. It all depends on the motherboard capabilities. Others I have seen you can go as far as raid 5 where you can have four hard drives of the same type. example 4 3 Terabytes and almost up to `12 Terabyte across all four disk combined. And even if one of them fails you can still rebuild the replacement drive from the other three. I have seen this done on some machines that are capable of doing it. Even on a raid 1 system. |
