JBOD or RAID0?

post #1 of 6
Thread Starter 
Hey,

So I'm having a hard time deciding what to do with the new drives that I'm gonna buy this summer. I want to put them all together so Windows sees it as one logical drive, and both can acomplish this.

JBOD doesn't provide a performance increase, but I HEAR that it also has a much lower failure rate. I dont like buying new drives/RMAing, so thats good. I've had the same 160GB drive for three years now...got a raptor which was a big step for me.

RAID0 has performance increase, but with a higher failure rate. Like I said, I hate buying new drives or RMAing them.

What do I do? If onboard controllers dont support JBOD, it'll be an easy choice, as I'm not dropping $300+ for a controller.

~Gooda~

All controllers support JBOD as far as i know, i would use RAID0 myself you get twice the capacity and twice the throughput. The high failure rate is exaggerated, i have never had an issue with dying hard disks or losing an array.

I would suggest raid0...hasent failed for me yet and it seems to work nice and fast. I really dont think there is much of a difference in failure rates so i would go with RAID0

The failure rate in a raid0 refers to the array going south, not the drive. Your drives will last about the same amount of time, no matter what sort of array you have them in.

Well the array going south would be because a drive failed, no?

It means that if your using twice the drives (for RAID 0), the likelihood of failure is theoretically twice as high because your using twice the amount of drives as opposed to JBOD, which in every compared example is only one drive by itself. But since you'd be using 2 JBOD drives, then the failure rate is still the same as the RAID 0 array. I'd defiantly go with RAID 0, I love my Raptor array . No matter what array you use, the failure rate for the drive will always be the same for each drive, it is not based on what array you use. What they mean is that if you use a RAID 0, since the data is on both hard drives, you are twice as likely to lose your data because if one hard drive fails, you loose ALL of your data.
