Hi all, I have been using my new baseline model 15" rMBP for a week now. When I first got it, I used Blackmagic speed test and got pretty good results, 400+ for both write and read. But now when I did the same test, the write speed is much slower, around 200, read speed is about the same though. Shutdown and startup speed seems slower as well but I am not sure, speed of running applications does not seems slow maybe because it's still pretty fast compared to a HDD. Is this normal wear and tear or is there actually something wrong with the drive? During the week, I downloaded some files, small and big, now the free space on the drive is around 135GB, installed a VM in Parallels, enabled Time Machine. I also encrypted the drive using FileVault 2. Thanks.
