RAID question?

[snidy1]

Is it posible to get the speed from a RAID 0 and still have reliability?

 

[snidy1]

Anyone?

Another question... Just exactly how unsafe is your data in Raid 0? What is the chance of stripe failure (?) or is it drive failure that will make you lose all your data? Is Raid is fine if you're not doing mission critical work and back up your .doc's regularly to CD per se? If you RAID PATA (7200rpm 8mb) drives through Serillel adaptors on the new IC7-G, will the performance suck?

If redundancy with speed is what you're after, look at RAID 0+1 or RAID 5; the Anandtech FAQ's have info on the RAID levels and what they do. RAID 0+1 uses mirrored striping - sort of like a RAID 0 array, with a mirror of itself; it needs disks to be added in pairs though. RAID 5 uses striping with parity, but it usually needs more expensive controller cards to handle the extra work of doing parity calculations.
RAID 0 itself - yes, the odds of losing data from random hard drive failure do increase, but not by a whole lot. From what little I retained of my Probability and Statistics class, the odds do not actually double, but they do increase by a little bit. Either way, it is still minimal, but you should of course still back up anything important.

Not without buying more hard drives to toss into the array or buying a pricier RAID controller. There's RAID 0+1 that performs well on softRAID cards as well as RAID 10 and RAID 5 that are excellent choices when using hardRAID cards.

Concerns about MTBF are for the meek. Get yourself an off-array form of backup and stop living in fear.

But the only way you'll actually fail if the hard drive itself decides to crap out, correct?

You can still get data corruption if you OC your system and the PCI bus is running out-of-spec. Some RAID controllers are also more prone to data corruption than others, so its not completely dependent on the HD failing.

What about using PATA drives in RAID on the ICH5R or is it the Silicon Image Chip on the IC7-G. How is performance through the adaptors? What is the optimal stripe size for such a config?

You should always back up your data whether you use RAID 0 or not, so even if it does fail on you, restoration should be no problem. RAID 0 is worth the risk, but remember to BACK UP YOUR DATA and you can't enjoy it worry free.

If you get a Virus and it's deadly then copied to RAID1...<Inset CRY Icon Here>best way performance and security wise that I know is RAID 0 then backup independently

Thank's for the info
