    Hi,

    Im wondering if my SSD might be broken.

    I get 75MB/s in Black Magic when using the 1GB stress-test.
    In the 5GB test i get the more normal 1300MB/s..

    Is this Normal?

    Is your computer slow?? Are you getting beachballs?? Are your apps suddenly slower to open?? If the answer to these things is no then I would just ignore it these tests are pointless unless you are troubleshooting a problem.

    I'm seeing similar behavior on my 2TB fusion drive on my iMac. The 5GB test, is showing faster access and the 1GB test is rather slow but the 5GB was fast all the way.

    It might just be a function of the 1GB file access vs. larger files.

    Went by a store today and tried another MBP with the same SSD and got around 500-600MB/s in the 1GB test.
    So, guessing mine is broken.

    My MacBook Air MID 2013 512SSD <- I know not the same

    1Gb
    W702
    R721

    5Gb
    W702
    R721

    The way I am I wouldn't be able to stand it unlike the other guy who doesn't care unless he has beach balls. I would format and reinstall but I don't know if that would fix it, maybe someone else has a better idea.

    Its not that I don't care it's that I wouldn't know, I wouldn't test anything unless my computer was not acting as expected, why would I waste my time and worry with this nonsense if my computer was working fine??

    The Op hasn't stated there are any issues with his computer so my assumption is that it is working fine, if that is so why would you bother testing the disk speed or care what those benchmarks said, if it is performing poorly then he should get apple to look at it.

    It´s functional but it´s been slower lately. Apps bounce in the dock a few more times, my desktop takes several seconds to load all icons. And browsing photos in Adobe Bridge started to get really slow..

    So, I tried a benchmark but since I did not take the 1GB test when it was new I did not have a reference.
    Thats why I started the thread.

    Contact Apple then, and see what they say, i.e., send it in for repairs.

    Well if you had explained that you would have got different advice, take it into apple and get them to check it out, they are the only ones who can give you a new SSD for it and it should be covered under warranty or even consumer laws if your warranty is up.

    For me its not a "waste of time" to spend five minutes to verify that my hardware on a 1400$ computer is working properly. Thats the way I am you are different its fine, but for all you know your computer could be running slow and you just don't realize it.

    It's a 2015 computer.

    You have a warranty, make use of it.

    It is normal for any 128 Gb SSD with the 1 Gb stress test.
    No needs to return it.

    Maybe the store MacBooks had a different setup (FileVault non enabled ?) ...

    No, neither mine or the one in the store use FileVault. Same MBP, same SSD.

    Don't know why ... it must be the test.

    I tried mine and two others at the Apple Store: same results with the 1 Gb stress test...
    Let me know what the Genius will tell you, but your drive doesn't seem defective.
