Hi all! I received my mac mini two days ago and I installed 2 same exact SSDs with the OWC kit. These are Adata sx900 128gb SSDs. I made a raid 0 volume with 32kb stripe-unit. The read speed is +/- 800 mb/s but the problem is the write speed. I only got +/- 320 mb/s... Is anyone have an idea why I got these poor write performance? Thanks!
