Buying new drives for my internal storage

Soon, I will be changing my drive setup from

4 x 500GB WD Black (RAID 10)

to something that uses less power.  Heat is my concern.  I was thinking of moving it to

256GB SSD (OS & Programs)
&
2x2TB (RAID 1) for Storage

My question is...which HDD should i buy?  RED?  Black?  Green?

I am leaning towards RED but don't see any info on using them inside your PC.
I do like keeping the PC on most, if not all, the time.

Thanks

The green drives will power down after a period of no activity which will reduce heat and power usage. Black is meant for servers, NAS and drives that need to respond quickly to requests for data.

Your best bet is a green drive. I suggest making a spreadsheet with common data for a series of drives that lists power brand, capacity, model, type, consumption and heat generated.

Green drives are not designed for 24x7x365. They are designed for a whole 8 hours a day 300 days a year use.  So forget them.

Red are light use NAS and the best quality compared to black.  Go to the wdc site and look at the detailed specs. They will show you BTU and power requirements when disks are busy and idle.  Then just do the math.

But if you care about data integrity and want to get a HDD that will have fewer errors and last longer, go with 2 x 2TB RED drives instead of black.   ((Plus SSD of course) for the rest.

But you're wasting your time looking at HDDs anyway to save power.  Your CPU alone could easily consume 20X more power than both HDDs combined.  Add high-end graphics  and the number could jump to 50X.

True.  But i need to upgrade them for space reasons as well.  

The CPU and GPU upgrades will take into account power usage as well.
