If I already have a hard drive installed with windows 7. Can I add 2 extra hard drives in raid 0?

Is it called Raid 0 if your storage is raid 0? or do i format that hard drive. install the two identical hard drives and put windows on it, raid 0 them and than add my old hard drive?

Yes you can add 2 extra drives - for raid 0 you must have two drives - you will also need a raid controller as well

In order to create an array you'd have to reformat.Your best bet would be to put 2 drives in RAID0, and then copy data from your existing drive as you see fit, after you've installed windows on the array.Then, you can add the third drive to your RAID0 array and expand your partition to take advantage of the additional space.Side note: I would not recommend using more than two drives in RAID0. If a singluar drive fails, you lose ALL data on the entire array. The risk of failure increases exponentially the more drives you add into a RAID 0 array. If you want a bit of redundancy, I would suggest RAID 5. You lose one drive's worth of capacity, however if any singluar drive fails, you retain all of your data. Once you replace the failed drive, the array will rebuild itself onto the new drive and you will once again have a failure tolerance of one drive.

raid zero or 0 means no data will be saved if you have a hard drive failure...Raid 1 will copy 1/2 the data to one drive 1/2 to 2nd drive if one drive dies data can be rebuilt from surviving drive.Raid 5 is multiple drives and can be mirrored or stripped (0,1)raid 10 is multiple redundant raid then there is JBOD or just a bunch of drivesthey can be any size make model speed etcdrives can be set as one big massive drive or set for speed and less spaceand data recovery

I read your question as:1 OS drive + 2 data drives in RAID 0Yes, that is easily set up (assuming your PC supports RAID0) Depending on the RAID controller, you may be able to add additional drives to RAID 0. Not all RAID controllers allow that, however.The warning about multiple drives in RAID 0 is accurate. If you're really looking for speed, the best combination is a SSD OS disk and the data disks in RAID 0.If you dare to go for RAID 5, please get high quality drives (e.g. WD Black, Seadgate Barracuda). General purpose disks that work fine in PCs can attempt error corrections that require a RAID rebuild. The last time it happened on my i7-920 PC with Seagate 1.5 TB drives, it took 3 DAYS of continuous operation to rebuild the array.Avoid JBOD at all costs - it does nothing useful, and can lose lots of data if any single drive fails.
