Whats a raid

A raid is where a bunch of people bust into your house and....

RAID = redundant array of inexpensive drives (usually the inexpensive part is a lie) RAID is broken down into "levels", typically, with the higher the level = the greater the redundnacy

RAID 0
- technically not even RAID because its not redundant
- Take two drives, stripe them together for theoretical 100% improvement in performance and 50% efficiency in space. Realistically performance improvements are in the 30-40 percent range

RAID 1
- Clone one drive on the fly to another
- Perfect redundnancy at 50% efficiency

MORE RAID

what do you mean? you want made a raid 0?
most of the raid card have their bios,you can enter it when computer startup where you can made a raid0
 
Gotta stop making threads on stuff you've partially asked :P
*Merges threads*

1. Get RAID controller
2. Plug drives in
3. Enter RAID BIOS
4. Configure accoridng to onscreen instructions :)
 
If all you want to do is stripe the hard drives you don't need any more hardware than you already have. Windows 2000 will stripe or span several hard drives into one volume, you must however use a dynamic partition. You can do all of this under disk management in Windows 2000. I haven't tried it in XP Pro but I'm pretty sure it will work.
 
Aye but with soft-raiding brings just the natural "uneasiness" to it :) (well for me at least)

what is a raid controller???? what it for do u realy need it??? :eek: lol

everyones mobo has an ide controller for your hd/cd/dvd drives. a raid controller is similar but it only takes hdds and can span data across them for backup, speed or most can make them jbod and it acts as another IDE hdd controller.

so you don't need a raid controller unless you want a large number of hdds or you want speed/data backup in the form of a raid array.
 
ok so if one were to have a situation similar to this:

which i dont, but for the sake of the question, praetor mentioned that raid0-raid4 are mostly scsi setups. so raid doesnt require sata? (for clarity of mind)

and, the size of the disks doesnt need to be identical for the striping to work efficiently?

next, this may be ignoram-ish but ive noticed that when ppl talk raid setups they mostly have WDs ... is there a reason for that other than higher quality/speed when it comes to striping?

finally, in as-close-to-lay as possible, what is the REAL advantage to raid, if computer is, say, not really being used for anything high-end -- no real gaming, editing, design, or anything else that may suck up precious brainpower?
:rolleyes:

Depends on the controller. A lot of motherboards nowadays have onboard RAID 0 and 1.

Not necessarily, though I'm pretty sure you lose the excess. Most people like to have identical drives in RAID setups (size,make, model)

A lot of people who use RAID0 just want as much performance as they can get, no matter the cost. The performance difference is quite minimal though.

Basically, striping for speed (theoretically at least) and cloning for dupilcate data in case of failure. There are inherent dangers in RAID0 because if you lose a drive you lose everything. And statistically speaking there's 2 times the chance of losing your data... and the performance gain isn't too much either unless you're looking at benchmarks.
