Hard drive prices rising???

I remember buying a 1tb wd blue for my first computer for around $40 nzd new but now I want to go set up a nas and i checked 1tb hdds are around 80-90 aud. Ssds with the same storage are only 10 more? Has the price gone up for hdds or have I just been out of the game for a while?

Should I just go for ssds seeing as they are $10 more for the nas?

Edit: I’ve gone ahead and bought second hand 1tb segate drives for $14 each shipped. Have really low expectations but will test them and update here
