    I just did a reformat of my Late 2011 MacBook Pro that I have 2x internal Samsung 850 Pro 512gb hard drives in RAID-0 Striped configuration.. The last time I set up my MBP with these same exact drives, I was getting close to 1000MB/sec read and read/write, now I'm getting hardly anything!

    I have the RAID-0 set up with the minimum block size (16K), just like I had before.. And before, I was hitting ~990MB/s write and ~990MB/s read!!

    Could somebody please help?! I need to get my system back up and running ASAP and I can't go ahead knowing there could be something wrong!! I am running a fresh re-format/install of OSX Mavericks 10.9.5! thank u!!
