PSU worries

[FNHack]

I'm having some concerns about powering a HDD from the dreamcast. After some searching I found this post from member ozone...

“btw, it’s probably not a good idea to run a big HDD on the poor DC power supply.
It struggles slightly to spin up (fan slows down for a second), and will probably kill the PSU eventually.
I’m running the 80GB from the DC PSU atm, but it’s worth mentioning that it could damage something in the long run”.

Does this include 2.5" drives using the 44 wire cable or is the concern just towards running a 3.5" 12v drive directly to the psu?

Any help would be great, thanks for you're time.
