I got the 2TB version

Didn't know. Too late already.

I think these are China resellers... thats why ship from China.
HDD remain the relatively stagnant since the Thailand flooding from few years ago... never gone done after that.

Gone up during MCO.
There is only 2 HD manufacturer and both of them share together.Even now , Toshiba just enter also same as them.

All 3 hard disk manufacturer possible on price fixing and even downgrade together at the sametime as you said PMR/SMR.
You will not see any price change as long as no HD manufacturer fixing the price.

Not all 1TB is PMR since external hard disk passport/expansion with unknown info.

Because of SMR ?
Normally i don't consider as drop , if 8TB drop means 2TB and other size must drop as well.If 8TB drop , why lower size HD price are fix ?
And 8TB , not any people going to buy since it's over 1k.
If you look at 500gb 2.5 for internal HD never drop below rm100.Youcan't find any WD or seagate 500gb 2.5 inch for RM100.They prefer to increase the size to 1GB and market with higher price.
You will get more reply at SSD thread.
Simple answer is getting a good controller + dram if you are using for OS and if you are using for storage and seldom access like storing photo and video for editing anything will do.
OS is a different issue as you need a good controller to r/w non stop.Just look at your win10 log I/O or process explorer you'll know.
