I just noticed that raid is the latest craze in the industry. I’m not ready to write a book on it, but I would like to make a confession about raiding backups. I’m not kidding. I do this all the time.
It’s pretty much the same as any other backup solution except that instead of just backing up anything, you keep it as a backup. Most backups are just a backup of something else, and once you’ve backed up everything, it’s basically useless. This is the kind of thing you should do if you plan to backup or restore any data after a disaster, but that doesn’t mean you should just backup everything. As with any backup solution, you should only back up what you need.
If you have an external hard drive, you should be backing it up to an external hard drive because you dont want your backup to get corrupted. That is, you don’t want to lose all your files, but you dont want to lose all the data of other users. If you dont backup your files, you can become a victim of a disaster and lose all the files on your other external hard drives.
raid is great for backing up data. If you have a huge backup, you can have the data in the backup, and when disaster strikes you can just restore that backup to a new external hard drive.

Raid is not the same thing as backup, though these two are often confused. RAID stands for: (1) Redundancy; (2) Adaptive Redundancy which means that some of the disks are not needed, and you can use them to replace the failing disks. This is something that really only makes sense when you have huge amounts of data, and that’s why RAID is such a good idea.
Raid is a great way to backup data that you might have on your computer, but not really your files. Raid lets you use an array of disks to replace your hard drives, and to do this you have to choose the disks at random. This is great if you have a lot of files, but it’s bad if you have a big amount of data.
That last sentence is a classic example of a phrase I find myself using a lot lately. It’s something I call the “Raidy-ness” because it’s basically saying, “I’m not going to use RAID, because I’m going to use SSDs to replace my hard drives. I’m not going to put a lot of data on them, but you’re welcome to use them for backup.
If you have a lot of files, its bad because you have to choose the disks at random. Its bad because youre not going to have a lot of backup because youre not going to have an SSD because youre not going to have RAID because its not going to work. If you have a small amount of data, its bad because youre not going to have RAID because its not going to work.
RAID is a very important and necessary technology for storing large amounts of data in a reliable and efficient manner. RAID is one of those technologies that is used all over the place, but because I have a good grasp of RAID (and a very good grasp of SSDs, actually), I believe its use is necessary for any home or business that uses RAID for anything.
