    I just picked up a pair of Crucial C300 256 gig drives to replace my old pair of Vertex 128s. I was really after the additional storage, but there was a nice little performance boost, too. Just posting my results in case anyone else was considering going with this config.

    Original config:

    System Info
    Xbench Version 1.3
    System Version 10.6.7 (10J3250)
    Physical RAM 8192 MB
    Model MacBookPro8,2
    Drive Type OSX
    Disk Test 283.10
    Sequential 251.66
    Uncached Write 433.68 266.27 MB/sec [4K blocks]
    Uncached Write 351.24 198.73 MB/sec [256K blocks]
    Uncached Read 109.02 31.91 MB/sec [4K blocks]
    Uncached Read 637.22 320.26 MB/sec [256K blocks]

    Uncached Write 112.98 11.96 MB/sec [4K blocks]
    Uncached Write 450.32 144.16 MB/sec [256K blocks]
    Uncached Read 2312.30 16.39 MB/sec [4K blocks]
    Uncached Read 1163.62 215.92 MB/sec [256K blocks]

    New config:

    System Info
    Xbench Version 1.3
    System Version 10.6.7 (10J3250)
    Physical RAM 8192 MB
    Model MacBookPro8,2
    Drive Type OSX
    Disk Test 478.51
    Sequential 278.08
    Uncached Write 492.71 302.52 MB/sec [4K blocks]
    Uncached Write 632.14 357.66 MB/sec [256K blocks]
    Uncached Read 105.52 30.88 MB/sec [4K blocks]
    Uncached Read 771.93 387.97 MB/sec [256K blocks]
    Random 1713.59
    Uncached Write 2320.64 245.67 MB/sec [4K blocks]
    Uncached Write 1110.99 355.67 MB/sec [256K blocks]
    Uncached Read 2232.56 15.82 MB/sec [4K blocks]
    Uncached Read 1800.64 334.12 MB/sec [256K blocks]

    Maybe it's not benching as high as the stated specs for a Vertex 3 240gig, but these were cheaper and available. Besides.. how much performance does a laptop actually need?

    Wow.. I just ran xbench again and got a top write of 409 and a top read of 422. Is that even possible?

    Is the original config with just one C300? How much faster are they in RAID 0?

    The original configuration was 2x OCZ Vertex 128 drives running in RAID0.

    Sorry, I haven't had a single drive config in more than 2 years so I wouldn't know how that would be.

    The first benchmark I posted was the original config I just described again and the second is the new one that I just installed this evening.
