More about RAID and other multi-disk setups
A few days ago I posted something about arranging hard drives in what is known as a RAID configuration. And now I see that Steve Bass is talking about RAID over at PC World. Bass says he doesn’t like RAID although he is really referring to RAID-0.
In any event, I agree that the average PC user doesn’t need the complications of RAID. If you have the extra money, however, a second internal hard drive running independently has its virtues. That’s the way I run my desktop. Laptops, of course, are another story. Whatever your computer arrangements, it might be wise to have an external hard drive connected by USB or Firewire for backup. Newer motherboards also provide for external SATA (eSATA) drives and this type of connection is starting to appear in external hard drives. I actually have an eSATA port on my newest desktop but I am still using USB because I already had several drives with that type of connector. My old 80 GB Maxtor seems small compared to the monster 500 GB (even 1 terabyte} drives that are now common but it is still chugging along, backing up my data files. I alternate it with a newer 400 GB drive. To illustrate how hard drives keep getting bigger and cheaper, the 400 GB drive cost about half of what the 80 GB unit did.
