RAID:4 Hardisks as 1

If I have four 100G hardisks, is it possible to use IDE RAID function on the motherboard to make it as one drive to produce a 400G hardisk? In windows, will it appear as a single drive? Should it be RAID 0 or 1?
 
with 4 drives and you want to have the total 400GB available , RAID 0 is your only choice.
If one of the drives fails you loose all data , just an FYI..

Which version of Windows are you talking about ?

 
you dont really want raid, you want JBOD (just a bunch of disks) .. why?, raid would do this but .. its not exactly what you want .. why do you want this? windows is the only os where this is even sorta useful, and i use "useful" loosely .. if u have win2k, make a spanned volume in disk administrator .. good luck ..

Ummm....to summarize, you have two choices, raid 0 (stripe) or JBOD (span) the 4 drives. Both give you a 400gb drive. Spanning the 4 drives will give you normal performance, whereas raid 0 will theoretically give you better performance.

The problem is if one drive fails in a raid 0 array, the whole array is screwed and you lose your data. Does anyone know if you can recover a spanned volume if one drive fails? Say you have data on all 4 drives, and one fails, can you recover the data on the other 3?
 
raid 0+1 is striping with mirroring, you have a set that is striped, and another set that mirrors the stripe set, what you are talking about is a JBOD .. ..

RAID 0+1 is probably the method that would be most beneficial to you. This would only leave 200GB available, but it would give you increased performance and data backup at the same time.
 
i got 3 drives and they've been running fine... sometimes at 160fsb... 😱 ... although they're not as big as yours... what are you gonna put in there... por...? 😉
 
You Just install a Bunch Of your Disks as normal. i.e. what you have now if you don't have RAID setup.

Have you considered having 2 RAID-0 setups of 200GB each?
 
When you set it up as JBOD, the controller puts the four hard drives together so that your OS sees it as one big drive. When you store data on this setup, the data goes to the first hard drive, and when that hard drive is full, that data goes to the second hard drive, and so on. In this case, you get no performance boost since you are only writing data to one drive at a time.

For a raid 0 with 4 drives in your case, the controller splits a chunk of data into 4 smaller chunks, and writes each smaller chunk onto one of the 4 hard drives simultaneously. Theoretically, this would be 4x faster than if you wrote to only one hard drive at a time.

Both of the above setups give you a 400gb drive.

For raid 0+1, you are doing raid 0 with two drives, and the other two drives act like backup drives. This gives you both performance and security, but only gives you a 200gb drive.
 
Oh my God! I would never use JBOD! It makes 4 hardrives' usage and lifetime different. By the way, where can I enable JBOD?
