Server Hard Drives -- 2.5 vs 3.5 inch SAS drives

Do you recommend 2.5 or 3.5 inch
drives for the below that I plan
to purchase ?

I am thinking 2.5, but they cost more,
therefore I might do 3.5 instead since
I do NOT need ALOT of space, therefore
I do NOT need to get the SMALLER drives.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

The direction is towards smaller drives in the future, depending on how long you plan for the server, the 2.5 while costlier now price premium is narrowing.
With the 2.5 you can have more expandability options.

What are you planning to use the system for?  

Have not looked, but it is either 8or12x3.5 or 16 or 24 x 2.5?

Fileserver I would not pay the premium for 15k drives but stick with 10k while getting the h710 raid better.

2.5" disks are usually more economical, as they use less power and generate less heat. So even if they are more expensive to buy, they can be cheaper in the long run when you consider your electricity costs.
The 3.5 will become more expensive in the future.  Look up the cost of a 3.5 SCSI.
Also compare RPMs
Tony GiangrecoCommented:
The trend in servers has been moving to 2.5" drives for a while. On most servers, you will see more 2.5" drives offered than 3.5". The 2.5" drives normally require 1/3rd of the power to run compared to the 3.5" and less heat is generated meaning a lower operating cost over time.

As time progresses, if you buy 3.5" drives and you have one fail, the replacement drives will be refurbished as manufacturers move production toward 2.5".
