Hello So I upgraded my Hard Drive from 256 GB SSD to the 480GB OWC Aura Pro 6G SSD which promises speed up to 555MB/s read and 532MB/s write. What I'm getting is about 500B/s read 250MB/s write. My original SSD delivers about 266 MB/S read and write. I don't know why? I have made sure that all applications are closed but speed has not improved. So my question is, would the problem be in my computer or in the OWC SSD? Or this is normal? Or should I call OWC and ask for a replacement? I just want to make sure before I do anything, I know what problem might be. Thank you in advance!
