[cobble_conductor]

recently i was looking for hard drives for my brothers new gaming setup. i bought two hard drives one as a game drive and the other as random other media.

 

for his other media drive i got a 

Seagate BarraCuda 4TB Internal Hard Drive HDD – 3.5 Inch Sata 6 Gb/s 5400 RPM 256MB Cache for Computer Desktop PC – Frustration Free Packaging ST4000DMZ04/DM004 

Amazon ASIN  B07D9C7SQH

 

for his game drive i bought a 
 Seagate FireCuda Gaming (Compute) 2TB Solid State Hybrid Drive Performance SSHD – 2.5 Inch SATA 6GB/s Flash Accelerated for Gaming PC Laptop - Frustration Free Packaging (ST2000LX001)

  Amazon ASIN  B07H2F3741

 

what i intended to buy

Seagate FireCuda 2TB Solid State Hybrid Drive Performance SSHD – 3.5 Inch SATA 6Gb/s Flash Accelerated for Gaming PC Desktop (ST2000DX002)

Amazon ASIN B01IEKG2HM

 

i am building him a PC DESKTOP, is there a deficiency if i use a 2.5 inch drive in his PC or should i get the 3.5 inch FireCuda drive?

 

thank you for any replies.

grateful for any help,

afaik, they're just different sizes, if they're both identical in terms of specs, a 2.5 wont perform worse.

1".

 

Other than that there isn't really any difference performance wise

Though, SSHDs aren't really worth their added cost.

the 3.5 in drives are normally faster for a give size + rpm

 

 

But its probably not worth the effort to return.

thank you all for a less than 5-10 minute response to my question.

Would say price (smaller for the same function costs more), but you've bought them anyway

actually for some reason the 2.5 was a rough $60 cheaper for me at time of purchase but i did go with a 3rd party seller

2.5 drives also use less power, though that really isn't an issue on most builds.

2.5 inch and 3.5 inch are just form factors. 

There are 3 common form factor: 

3.5 inch

2.5 inch

1.8 inch

It is basically the width of the drive.

3.5 inch drives are the "best" drives you can get. 

They are the fastest, have the most capacity last the longest and they are usually quieter than the other drives.

I would never use a non 3.5 inch hard drive in a desktop pc. 2.5 and 1.8 ich drives are superior in size. A 3.5 inch drive would fit in most notebooks therefore 1.8 and 2.5 inch drives where used. 
There is another advantage of 2.5 inch drives: they need less power which makes them usable as a portable drive. 3.5 inch drives need relatively  much power. 2.5 inch drives can be powered by an usb Bus. A 3.5 inch drive would need external power A 2.5 inch drive can be plugged with a single USB cable. 

 

There are to many drawbacks with 2.5 inch hard drives I wouldn´t want to use one in my desktop setup.
