Thread: Raid 0 Usefulness ?

    Default Raid 0 Usefulness ?

    hello

    been reading up on Raid 0, seems that alot of website claims the the benefit is only in the benchmarks, and no real world improvement in performance. Any experts in this field ? or any real world experience in using Raid 0 ?

    cheers

    Raid 0 increases maximum throughput. Very useful when transferring large continguous files.
    However, I'd say its not worth the risk, I was running on Raid0 for about a year until a HDD crash wiped out all my info. The increase in performance is real.

    Bear in mind that in this configuration(striping) having either HDD fail will result in your data lost.

    IC, the precarious way that raid 0 writes to the HDD, will a sudden shut down cause the HDD to go corrupt ? I friend had a whole external HDD go kaput when the power was cut off during a file transfer.

    yup, cos intertwine... for home user, use normal will do or use for mirroring, unless you are doing video production, yes Raid 0 for scratch disk... since no data would be in it after you are done...

    I read some where that Raid 0 work 2 times more than in Raid 1 or in normal HDD. This will, in a way, kill the HDD faster.

    This is all clearly stated in the your first link which spans MANY pages. Look past the first few pages and the advantages start to show.

    As for the 2nd, link, he doesn't really know what he's talking about. He's merely interpreting the results of other pples tests based on his own needs.

    If you have the hardware to test, just setup a RAID 0 configuration to see for yourself. Performance gains are REAL, but the risk is too great unless you are using it for swapfiles or have a 0+1 configuration which requires double the hardware.

    IC IC,

    was in a way exploring ways to keep my system running. With all the Hardware required, it seems to be cheaper to just sell the system and buy an upgrade :\

    try a ramdrive.. much much faster.
    or just use the raid 0 for programs and scratch. storage wise use raid 1 or 5.1/5.0
    sigh.

    Usually, you'd either do Raid 1 or Raid 0+1 but rarely Raid 0 alone. Esp if you are commercial. Raid 0 means you spread data over several disks. One failure and you are dead in your tracks. Your do get more throughput with very large file accesses. Traditionally, Raid 0+1 was used for databases.


    A couple of years ago, only large corporations used Raid.... now you can have it on some cheap taiwan motherboard...

    Me using RAID 0, it do speed up the performance,

    Eg, open a tif file of size ard 150mb take ard 60-90 sec, with RAID 0, only ard 15-20 sec,

    if use RAID 0, need to backup data frequently lor, if not "cry no eye ****"

    RAID 0+1 will be

    Unless you're willing to mirror a RAID 0 setup at the same time, I won't recommend it for mission critical applications like what I think you're doing.

    If you find your current computer sluggish, it's better to just buy a faster machine/CPU (if upgradeable) and pump its RAM to the max.

    The days of slow Photoshop because of slow drive performance is kinda history because of the cheapness of RAM and speed of CPUs now. The bottlenecks are at the BUS, RAM and CPU. Unless you're dealing with seriously humungous files that you constantly need to open and close, just buy the fastest single drive you can find.
