RAID 0,1, 0+1, 5? huh?

[legoalex2000]

first off, i must arise this question before continuing on. I plan to get a SATA/150 (max my mobo supports) drive (havent decided on space yet). so what i want to do is create a RAID with my two IDE's. but one is 30gb and the other is 40gb. will this work at all, or must both drives be the same size. if so, is it possible to partition off a drive to make equal space?

so what is the diff between RAID 0, 1, 0+1, & 5?

so im planning on a SATA/150 drive, im just wondering whats get me lots o spaceat min. price. mind you im going good qualtiy though, so like im saying a Seagate 250gb for such and such $, or a WD 300gb for this much $.

im gonna put it on my list, since my b-day is only 23 days away... or should i put the LCD's on my list... hmm...

Well the size of the drives dosnt matter, however you cannot RAID SATA and ATA drives together as far as I know. Also I dont personally think that the risk of RAID is worth the speed gain. Anyway look at the WD Raptors (10K RPM) if your looking for speed.

But if it were my B-Day, Ide get the LCD's

Just google up the info, there is plenty written about raid array types, but basically, RAID 0 is 2 drives for near double speed with no redundancy, RAID 1 is 2 drives with slower speed and full redundancy. O + 1 is a combo of the two, can't remember what the others are offhand.

2 x 250gb HDD's in Raid 0 gives a total of 500gb data storage, where the same two drives in RAID 1 gives 250gb data storage. You get redundancy with RAID 1 at a speed and capacity penalty.


Gamers are interested in RAID 0, for fast disk access.

The risk of RAID? You mean RAID 0, where if one drive fails you lose all data on the array.

Well, the same can be said for any hard disk setup. If you use 2 drives in RAID 0, it just means there are now two drives that could possibly fail, not just one.

Did this logic ever stop anyone from buying two RAM sticks ? Mind you, you won't lose your data if ram fails, but what I'm trying to say is...... if your data is that important, you should be using a redundant RAID 1 in the first place where two copies of your data are always present. A single drive can fail and you will lose your data. A Raid 0 Array will fail if a single drive in the array fails. If a drive fails in a RAID 1 array, the array can be rebuilt from the remaining drive.

How risk is measured is very personal unless the machine is used for some public task.

I recently set up my first RAID 0 on this PC, it's fast. I should have done it years ago.

Damn the torpedoes..... Full speed ahead!

I'm using a RAID 0, and I have three partitions.  Like CTJoyce said, I do not believe you can RAID an EIDE with an SATA.

You cant, but I talked with Alex afterward, and what he wants to do is RAID the ATA drives together, then use the SATA drive as extra storage.  Hes useing the ATA for FS and the SATA for everything else. Correct me if I'm wrong but its not a bad idea.

The 30 and 40gb drives will be configured as 2 x 30gb drives in RAID 0 giving 60gb capaicity in the array.

The SATA will be used as aux drive and backup for the important data on the Raid array.

Best to install the os and game to the raid array so that all important access is on the fast interface.

It would be far more preferable in any case to buy two new Seagate NCQ or WD SATAII drives at whatever size is going cheap at the moment, say two new 100gb drives for instance....... this will give 200gb in the raid 0 array with the two ATA drives giving a total of 70gb backup space for important data.

There is a strong argument for using my method in that two new SATAII drives are less prone to failure in the near to mid term (2-3yrs). Also, the SATA array will provide better performance and you'll be operating with more recent technology. Buying a single and expensive large SATA drive would be folly.

I am using two 200gb wd sata hdd's with two 80gb ata drives for backup. I disconnect the ata drives' power cables unless I'm doing a backup.
