My SATA host controller has RAID control built in. Easy then!

"My SATA host controller has RAID control built in." Sounds very impressive. But what does it mean?

It means that doing the RAID setup should be a snap! RAID = Redundant Array of Inexpensive Devices Means that you can get protection from individual device failures with cheap(er) pieces. Various levels of RAID exist - most peoples use RAID0 (that's zero) - ie nothing! and rely on the single drive in the box to just keep going. When it fails, we get all thingy and expect some poor tech (ie me!) to "get all my data back".

My intent was to set it up as RAID1, but I got busy with other stuff (and also lazy), so I've been just saving to the external drives.

I believe mine is RAID1. I never knew what it meant. ( Still don't  )

About this RAID thing, it seems we get a choice of none, RAID0 or RAID1 now with online customisation thingies. Which would you (the ones in the know) choose?

I'll try to make this as non geeky as poss... Raid 0 (striping) is for speed as all the disks get treated as one. If you have two disks in a Raid 0 set then you can read/write twice as fast because you have twice the amount of heads to use. It is actually a more dangerous setup as you are now exposed to losing all your data if any of the drives fail. But it is fast! Raid 1 (mirroring) is for protection. You must have an even amount of discs as each disc has a mirror pair. Data is written to both discs in a mirrored pair. If one drive fails in a Raid 1 set then its mirror pair carries on as if nothing had happened. You need to run monitoring software to tell you when a drive has failed. There are lots of other raid levels too, but these usually appear on server systems with lots of disks. So if I had a home machine with data on it that I really wanted to protect I'd choose Raid 1 and do some kind of regular off site backup.

Interesting that, I had no idea.
I have never heard of it. What config do most new computers come in?

Most "off the shelf" computers will come with a simple, single HDD. To incorporate RAID, you would have to add a controller card and a couple of additional HDD's.

Since reading this thread it has kicked me into action. I went out and bought a 500GB hard disc and am now backing up once a week.
