I am building a new system soon, I will have multiple 1-2tb hard drives for storage in it. I only have experience uasing the sataII drives but I saw somewhere that I should be using something like SAS? I read that if I were going to have 20 drives that I could use 4 SAS cables vs 20 SATA cables.
Can someone help me understand this better? If it were only 4 cables then how would 20 drives hook up? Also can a regualr sata2 drive hook up to that?
