SSD performance is BAD after powerup with Aspire TC-1660.

The SSD is a Samsung PM991 as far as I can tell. Here's the specs:

Benchmarking this SSD with CrystalDiskMark
  • the performance after powerup is awful and stays awful.  For example, sequential reads are 890 MB/s.
  • the performance after restart is per Samsung specs.  For example, sequential reads are 2280 MB/s.
It's totally repeatable.
What's with this?
How do I fix it?
