Make it big enough for Blackmagic to work with (7+ GB) and name it what you will. Create a disk image (.dmg) using the disk utility specifying file->new image->blank image. I found a workaround that will report the rates of the Startup Disk. When Blackmagic tries to read the Startup Disk, you get the message that the device is not writeable, hence you cannot rate the the transfer rates of the drive. This is when I realized I should go check the performance on the local machine.Blackmagic has been updated to adequately report the speed of SSD devices. It wasn't until I tried this network copying task the other day that I decided to run BlackMagic's test. In any case, the only significant change since the slow down is the OS, but the decline in performance was noticed in the fall. The performance at that time was roughly the same, although you might recall that the old app xbench no longer worked to give a comparison because one or more of the sections of testing wouldn't work (memory, if I recall correctly, although I will run it when I am back at that machine and post here). These changes did not happen when I installed Mavericks, I just don't have benchmarks *saved* to give the support community exact numbers after Mavericks was installed. I did a horrible job of explaining *when* the slow performance became noticeable.

Hard disk slowed to less than half the speed from Mac OS X 10.7.3, as I am now on 10.9.5 and the speed appears to be roughly 40M/s uncached write down from 119M/s previously. I cannot think of any significant changes to tools or background applications installed since that time, so I ran EtreCheck - the results of which I'm pasting below.Īny guidance as to what I should test would be greatly appreciated. Now, the drive running under 10.9.5 is performing very inconsistently, with top speeds around 80 MB/s and averages more like 50 MB/s. In the summer of 2013 running 10.7.3, this same hard drive had an uncached write speed of 116 MB/s and 94 MB/s. Luckily, I had saved xbench files so I had the ability to compare old disk tests. Suddenly I was horrified when I saw the performance for write operations well below the speeds I'd observed in the past. I was testing my hard disk via BlackMagic Disk Speed Test across the network (for copying files from my MacBook Pro to my Late 2009 iMac, and I was shocked at the write speeds.īecause of this, I went to the machine and ran local tests, both BlackMagic and xbench.
