    Asking Again - Just Differently (?) About RAID0

    Okay here we go again as I didn't figure it out the last time!!

    Is there anything to be gain by going RAID0 for everyday stuff???? Before you barf on your kb because of getting ill from the RAID0 mania give me one more listen. It will be built this time.......

    Turns out I was introduced to SSDs with a "prize", a 32GB Zalman. After loading Win7 (care to explain TRIM while we're at it??) I discovered just how little 32gb is. Any way thanks to ebay (again) I now have a 120GB G. Skill "Sniper" series drive. That is a given for OS and related. However I do have a 300GB VíRaptor "for everything else".

    So would doin' another VíRaptor in RAID0 help with stuff like photochop, video rework, games(?), whatever..........??

    Anyway this will be the last time I ask this......until later.

    Why F@H?? Click me!

    yes but due to fact if one drive goes you loose it all

    Re: Asking Again - Just Differently (?) About RAID0

    The only time that RAID-0 really makes an impact is when transferring large files to or from a different volume of equal or faster speed. So combined with a fast SSD, maybe yes but again really only with file transfers. In terms of access times and controller over-head, RAID can actually be a tad slower.

    A RAID-0 array is no more likely to fail than any other HDD. All drives fail eventually, and the person who neglects to back up his stuff will regret it.

    When it is all said and done there will be a RAID5 or 10 setup on the network using an external RAID box......

    That boldfaced portion is actually incorrect. Two drives in a RAID0 have a higher chance of failure that leads to a lost volume than a single drive.

    A statistically incorrect statement. 2 drives do not have a higher chance of failure than one does. Each drive has the same chances of failure. In any case, using simple back-up strategies makes it a moot point.

    Re: Asking Again - Just Differently (?) About RAID0

    Okay it looks like the idea of RAID0 is basically a waste.....as stated in the OP, for my main system I've acquired a 120GB SSD so should be good there and just use the single 300GB V'Raptor for my everyday stuff and work. I'll have my back up in the form of a 4 disk remote box set up in RAID5 as I have 4 x 1GB Blacks for that.

    Thanks

    Reread what he said.

    A RAID 0 volume made up of 2 or more drives has a higher probability of being lost than a volume on a single drive. That's the General Addition Rule of probability in action. For a simple two drive RAID array the probability of losing the array is nearly double the probability of losing a single drive.

    And while the RAID 5 backup is a good idea, it's still not fool-proof. External drives are cheap, as are on-line solutions.

    Re: Asking Again - Just Differently (?) About RAID0

    My systems are automatically backed up nightly via a Windows Home Server. I am only running a single SSD RAID 0 array (3x64 / 192GB) on one system and I donít keep anything critically important on the array in the first place. Iím more concerned about loosing a 1TB or 2TB HDD in my server then I am about an SSD in the RAID 0 array.

    Re: Asking Again - Just Differently (?) About RAID0

    For a little further on the failure statistics - think of it this way. Let's say you have two drives in a RAID0 array. Let's further say that there's a 1% chance that one of those drives fails within a year.

    If you instead are using one drive, the odds of you having a crash that stops things from working is 1% (the chance of your one drive failing).

    However, in RAID 0, if EITHER drive fails, neither one has enough information for things to work. So The odds of you having a crash that stops things from working with 2, at 1% each, would be a shade under 2% (1.99). [This can be figured by calculating the chance of not having a failure. .99 x .99 (99% chance of either drive staying up) = .9801, 98.01%.

    http://en.wikipedia.org/wiki/Standard_RAID_levels has the math for each type of RAID setup, as far as failure rate, performance, and the like go.
