2.5-inch Mounted Hard Drives Vs 3.5-inch Mounted Which Is Better.

Here is the question which type of drives do you think is better.

In both my laptop and desktop i prefer the 2.5-inch drives.

Here is why main reason less space.

I find that the big bulky drives tend to get in the way.Especially with Air flow.Air Flow is Key for keeping a laptop or desktop cool all year round.

There's not much difference in reliability.They could last you up to 10 years or more.Or they could die on you as soon as you plug one in.

Compare the differences.

A regular Hard drive will last longer for the most part longer then a Solid State drive.Solid State drives only last a couple of years.Compare that to a regular hard drive which like i said can last 10 years or more depending.

The 2.5 drives can be a little more expensive,Then the 3.5 drives.You can buy 3.5 in bulk lol.

 

I prefer enterprise 3.5" drives. The 2.5" form factor is handy for external drives and laptops but the 3.5" form factor with bigger platters also has better data density. I also believe the 3.5" drives are a bit more robust but with their lower mass, it could be argued that the 2.5" drives have been engineered to have better vibration and shock resistance.......I know they both don't do so well after a fall from the bench to the concrete floor ......the only winner in the drop contest is the SSD

Price wise you get more storage for the money in 3.5" than in 2.5" HDDs.

Another consideration is power usage and heat........because a NAS or file server is always running with multiple HDDs, the more drives become a power and heat consideration. For this reason NAS makers are now making smaller form factor NAS cases to suit 2.5" HDDs and SSDs. Although in the commercial market the 2'5" drives haven't had much impact. An acquaintance owns a very large server farm fed by five 10Gb/s optical fibres connected direct to the backbone. He reckons he is only going to restructure when he can get a better deal on very large SSDs that have more write cycles but until then he will stick with his >4,000 enterprise 3.5" drives because his HDD predictive algorithm software can accurately map HDD life performance so he can work out his costs before drives fail and factor this into his pricing so he continues to make a profit. He probably changes about 20 drives a week but they run 24/7 serving some of Australia's biggest companies.......... and the heaviest use drives get routinely swapped out when they reach 3 years old before they are likely to fail.

 

Nonsense, recent SSDs have the potential to last just as long as HDDs.

(Note the "over the coming weeks and months", which reads like they weren't sure they'd get 12 months of 100% thrashing from them.

March 12, 2015 (quote from the conclusion):

I use SSDs for System and some storage/game drives for speed of loading/Page files/frequently played games, etc. (basically anything that responds faster and/or is needed frequently) plus 2.5" HDDs for data storage and anything that doesn't change frequently; 3.5" drives would run warmer, require more power to boot up and run and are generally noisier; 2.5"'s generally more 'overbuilt' as they usually end up in notebooks with very limited airflow, so frequent high temps and occasional sharp knocks are expected. I have no need for multi- Terabyte storage so a 1TB storage (normally ~50% free space) + 1TB main backup/2x 1TB portable backup is fine for my main PC.
