Blackmagic is now faster enough to rate internal SSD speeds, even the Startup Disk
Blackmagic has been updated to adequately report the speed of SSD devices.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.I found a workaround that will report the rates of the Startup Disk. Its quite simple. Create a disk image (.dmg) using the disk utility specifying file->new image->blank image. Make it big enough for Blackmagic to work with (7+ GB) and name it what you will. Mount the volume (if it is not already mounted).In Blackmagic select the disk image mounted. Since the “volume” is on your Startup Disk, you will see how fast it drive is. On my 2016 MacBook Pro, I am seeing speeds like 1,000+ MB/s write, and 1100+ MB/S read. I have tried this on my older mackbooks with SSD and they do scale down as the device is older. On an older MacBook Pro the rates I see are 500 MB/S both read and write, as you would expect.I have run Blackmagic on USB 2, thumb drives, USB 3, and USB C devices to see if I’m getting my money’s worth. You can easily detect when a device is performing subpar and, and with the spinning disk, you can see is transfer speeds deteriorates over time.

Test the sequential or random read/write performance without using the cache. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD's access time.
Test Ssd For Bad Sectors
Two extra benchmark tests examine the drive's behaviour when copying a few big files, a lot of small files and a mixture of file sizes by using cached copy functions of your OS as well as reading/writing data depending on the data's compressibility.
The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Thrd 4K procedure except that the read and write operations are distributed to 64 threads. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The additional compression test can measure the power of the SSD in response to compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.
In the first three synthetic tests and the compression test, the size of the test file 1 GB. Finally the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. The write access test, however, is done with a 1 GB big test file.
