Hard drive prices

How is it that WD Red 4TB drives are still so expensive?  I simply don’t understand it?

I mean, I remember reading about floods back in 2011 that caused a shortage and drove up prices, but I bought a 4TB drive almost a year ago for cheaper than the current price.

The market is what it is, I guess.

For the record, we’re dropping the WD’s into a Synology DS216 for a customer.  Synology prices have become very affordable as time has gone on…
