Late 2013 13" Macbook Pro
Hi all new here and live in the UK. I've got a Late 2013 13" Macbook Pro (SSD) 256gb 8gb ram under 12 months old. I had OS X Mavericks when new and I've updated to OS X Yosemite. Now when I had Mavericks and using Blackmagic Disk Speed test I got around 680MB/s Write and 700+ on Read first screen shot. But now I'm only getting 350MB/s Write and 560MB/s on Read second screen shot (Media Name: APPLE SSD SD0256F) is this normal with updating to Yosemite????.
Medium Type: SSD
Protocol: PCI
Thanks Michael.
MacBook Pro with Retina display, OS X Yosemite (10.10)
