Hello all,

I have this issue with several Samsung PM1633 SSD's in my Unraid server. Long story short, everyone of these drives can only read/write at ~50MB/s. At the same time, I have a couple PM1643a drives that read/write at ~900MB/s. I was going to attempt to write the PM1643a NA03 firmware to the PM1633.

At this point, I am just frustrated trying to figure out why these drives aren't performing as expected. If anyone can help, I would be eternally grateful.

link to another thread I am trying to do the same.
