Thread: RAID w/ diff Caches?

    Sup.

    Ok so I have two drives:

    Maxtor 6 L080J4 -- 80Gb w/ 2Mb Cache
    Maxtor 6 L060P0 -- 60Gb w/ 8Mb Cahce

    And an Abit KT7-RAID mobo with dual ATA100 RAID channels.

    Both of the drives are 7200RPM, ATA100. I am wondering if I could RAID 0 these, (striping), or would
    the difference in the cache sizes screw up performance horribly? I am not concerned by the fact that
    I will loose 20Gb, as long as there is a disk throughput increase.

    There is only an increased storage rate, but it is NOT wise to try it with two different drives, that would probably slow both down substantially.

    OK thanks!

    I actually had already done this with the two drives but I thought that perhaps it was slow because I used FAT32 on a 120Gb partition. But, infact it wasn't the fault of the FAT32. It was the Cache.. :confused: Duh.

    Thanks again zeradul!

    For RAID to work properly without any conflicts/problems it's highly recommended that the drives be of the exact same brand, model and size.
