I go with this, a 3.5" will need both 12v and 5v supply to function
correctly (aiui :rolleyes:)

Here's the spec on max power the pi can supply to the drive controller:
https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#maximum-power-output
. So, just insure that your drive/controller is less than, say 80% of
this.

I think your (OP) reference to size is you currently have a 2.5
controller enclosure and you want to use a 3.5? If so, get a different
controller, they are inexpensive (Ive used Vantec)

A 3.5" external drive will probably need a dedicated power supply
whereas most 2.5" do not.

It would be absolutely fine. An HDD's an HDD so far as the RPi is
concerned.

> Also is there any benefit to doing this.? 

Depends on:


- what RPi you have — ie, whether it supports USB 3.0 (RPi 4) or not
  (other RPis)
- the spec of the external drive you're currently using (ie, is it USB
  3.0?).
- 
  

If your RPi only supports USB 2.0, then there won't really be any
benefit, as that will be the limiting factor, regardless of the HDD or
enclosure specs. 

If your RPi supports USB 3.0 (ie, it's an RPi 4) and you get an
enclosure with UASP SATA 3-to-USB 3.0 , then it will achieve faster data
rates than an external HDD that's just USB 3.0.

> Also dont I need a adaptor to use it due to its size.?

Not quite sure what you mean.  You just put the HDD in the enclosure and
there'll be a USB cable that comes out of it which goes into your RPi
