I am deciding whether to get 3.5 or 2.5" hdd for my receiver that is passively cooled and has no fans. From what I understand 3.5" radiate more heat, but I don't know how significant the difference is. Obvious advantage of 3.5" is larger hdd for the same money.

 

Appreciate if someone can share their thoughts or experiences.

In terms of heat is is significant as well. I could always feel the heat from the disk on the outside of the box, I can't with a 2.5" disk.


Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)

Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

A 2.5" SSD has almost no heating and more important it's noiseless.;)

But is quite a bit more expensive. While the box has absolutely no use for the speed of an SSD disk.

500 GB SSD only 150 Euros, silence has no price...;)

Nearly no benefit, therefore wasted money, and 500GB is also rather tight if you want to do some proper recording. Recommended buy is a 5400 rpm 2.5 inch disk. Completely silent, cheap, lots of capacity.

No 2.5" disk is completely silent ... maybe you don't hear it... but I can... ;)

I would like at least 1TB, preferably 2TB, so SSD is way out of my budget unfortunately.

 

I've been researching a bit since asking the question and I'm getting conflicting information whether 2.5" hdds are consistently quieter and use less power (which is obviously directly heat to the amount of heat they generated).

 

What would be good quiet models with low power consumption? 1 or 2TB

There are also dedicated PVR 3.5" HDDs; they work on approx 5400RPM, and have the same heat and noise performance as 2.5" HDDs, but are less expensive.

I've been using them in several boxes and never had any heat /noise issue.

Having said that: 2.5" HDDs are becoming less and less expensive.

2.5 inch disks use a lot less power than 3.5 inch disks, often as little as 1 watt. They are generally also very silent, allthough as Rob says, 3.5 inch can be silent as well.

The Western Digital Blue PC mobile and Seagate Baracuda 2.5 inch series would be a good choice. Generally, look for "green" hard drives, 5400 rpm, and you are okay.

An advantage of 2.5" disks is that they are more widely available than 3.5" PVR-HDDs. On the opposite side there are quite  number of 2.5" HDDs that are not as silent as they're supposed to be. I think you should (find &) read the manufacturers specs and reviews.
