Hard Disk Light flashing constantly new SSD

Hello, I have an older Acer laptop.  I decided to freshen it up with a new Ultra 3D SSD. I did a clean Windows10 install. The hard disk activity light flashes very fast all the time.  The dashboard doesn’t show any activity.  Kind of bothering me as I don’t want the drive to crash with too many writes to it.  Anyone ever run into this issue?  Dashboard said firmware is up to date.  Disk seems to run fast.  No programs running that I can see.  FYI, I did have Intel RST installed but I removed it. Still seeing  iaStorA.sys. 

Thanks in advance,

Mark

I have the same problem with videos.

When I play videos on youtube or a movie, the SSD gets a lot of activity. How do I reduce this?
