    Whats up guys?
    I made a raid0 with 64kb block in my 2010 mac mini server. But I was wondering:
    -I dont use any heavy application, only normal OS programs, safari, view PDF´s, iWeb, iPhoto, iTunes etc..
    -Would it best to use 32kb , 64bk or 128kb ?What would be faster to use the OS in general, open folders, and use those programs I mentioned ?

    Im in 64kb right now and opening folders is not THAT fast. Might even be slower than not-RAID0 7200rpm. I mean, for exemple, sometimes when I click to play a music it take a second or so to start, like it was in my old mini with 5400rpm. I dont really remember that well, but I think before the RAID0 some things were a little faster. Could it be the block size?
    Help me here! than you

    Lowering the block size is only a benefit if you have a significant number of files that are smaller than your current block size. If you have lots and lots of files that are smaller than 64k, you may see some speed benefit to switching that to 32k. But only if you're accessing lots of those files at once (one 60k file loading at a time isn't going to be sped up much no matter how you tweak things).

    Considering a 5MB music file, you will see little (if any) difference between a 64k block size and a 32k block size since in either case, the controller is going to split the file across both drives.

    Also, don't forget you are limited by the other hardware in the machine. The amount of time your CPU takes to process a music file is independent of the hard drive. If it takes a second, it takes a second. RAID won't help you there.
