Surprising in the moment, but not super surprising...

The graph presented there suggests prices should be falling quickly about now.

There can surely be some local price drops, with numerous plausible root causes...

- suppose a would be PC customer lost a contract causing a localized surplus of components

- suppose an SSD production line ran some spare shifts

Various sorts of logistical errors could lead to this.

And with prices tending to fall, not seeming too surprising on aggregate.
