Read/write (25.4/32.3) extremely slow after cloning.
I just purchased two (2) Crucial MX200 SSDs 500GB.
I have carefully followed the procedure to clone the SSD in my MBP. When the first one tested poorly, I cloned the 2d SSD and received the same results. They both initialize and startup but when I test them out on Black Magic they show 25.4 read and 32.3 write.
The old SSD (120GB) was 128-130 Read and 375.4 Write.
Can anyone suggest what my problem might be and how to fix it?
Thanks in advance for your assistance.
Is this a good question?
