    Hi all,

    I've just tested the times it takes to open three applications and am not sure whether the results are positive.

    PhotoShop opens in 2.1 seconds - Very positive.
    Premiere Pro CS5 opens in 8.43 seconds - Not so positive.
    Final Cut Pro 7 opens in 23.83 seconds - Pretty bad.

    Premiere Pro opens faster on my desktop with a regular HDD.

    Are these results normal/good/bad?

    Using QuickBench 4, my read/write speeds are averaging:
    Read: 267 MB/s
    Write: 230 MB/s

    Using AJA Speed Test, I'm getting:
    Read: 235 MB/s
    Write: 209 MB/s

    I posted the Application opening test on YouTube too:

    Why not just run AJA system test like everyone else? Your tests are showing numbers about the same as my SATA2 OWC.

    Added the AJA System Test results - they're even worse!

    Exactly what SSD is it? And exactly what system and setup are you running it in? If it's a SATAIII SSD in a SATAIII chipset, that's not good. But that's about as good as it'll get with a SATAII SSD or even a SATAIII SSD in a SATAII system.

    It's a SATA II (3Gb/s) OWC 120GB Mercury Extreme Pro SSD mounted in the optical drive bay (connected to a SATA II port). I'm running OSX 10.6.7 on a 17" MBP with 2.3GHz CPU and 8GB RAM.

    I keep seeing people's test results being a good 30MB/s faster than mine.

    That looks pretty normals read/write speeds for a sata II drive

    I get 250/245 on my SATA2 OWC, you are definitely low.

    Is yours in the main drive bay? Maybe that's where I should put mine.

    I have the OWC in the optical spot and the stock in its original spot.

    if it's in the odd bay - whats the negotiated link speed?

    maybe smc + pram reset

    Can you post a screen capture of your Activity Monitor's memory page? If your computer had insufficient memory available it would explain the Premier launch times.

    Usually the smaller 120GB SSD will be slower than the larger SSD. His speeds look about right to me.

    Link Speed and Neg. Link Speed are both 3Gb.

    The other bay has a Link Speed of 6Gb but a Neg. Link Speed of 3Gb (presumably because my SSD is SATA2).

    What does smc + pram reset mean?

    Here it is. I tried to capture it as it was opening Premiere but I think the screen captured just after it has loaded.

    Looks like there's plenty of RAM to go around right?

    the 120 is slower than the 240 SSD this is why your speeds are lower.

    Im still not sure why people would put the SSD in the optical bay before they put one in the HD bay. Seems backward to me.

    Because there's already a SSD (that came with the machine) in the HD bay. So now I have two SSDs inside.

    Does it impact upon performance to have the system drive in the optical bay?
