Is RAID-0 the sum of all the drives? - GoFuckYourself.com

Hi I have a newbie question about RAID. I have two 36gb SCSI drives here and want to connect them in a RAID-0 configuration. Will the final space available be 36gb or 72gb? Anyone please let me know thanks.

Raid 0 is good for fast perfomance but is not a true raid system, if a drive fails your fucked. To calculate the size take the smallest drive size and times it by the number of drives (in your case you would have 72gb) here is a handy reference

What do you mean its not a 'true' raid system? Raid is a specific way of setting up hardware, RAID0 is still a 'true' raid system, but theres more than one option in setting up RAID arrays.

In a RAID0 setup tho, if one drive fails its basically like every single drive in there failing and your data is kaput.

However, in raid0 the more drives you use, the faster your 'single' drive will be, so youre basically putting speed infront of redundancy and you'd better have a network backup

BTW yeah you would have ~72gb final space

The future is RAID5, you loose the space and need at least 3 hdds but if one gets fucked you dont loose your data ;)
