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.<br />

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.

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

True. &nbsp;But i need to upgrade them for space reasons as well. &nbsp;<br />
<br />
The CPU and GPU upgrades will take into account power usage as well.

<div class="content wysiwyg-content">
Soon, I will be changing my drive setup from<br />
<br />
4 x 500GB WD Black (RAID 10) <br />
<br />
to something that uses less power. &nbsp;Heat is my concern. &nbsp;I was thinking of moving it to<br />
<br />
256GB SSD (OS &amp;&nbsp;Programs)<br />
&amp;<br />
2x2TB (RAID 1) for Storage<br />
<br />
My question is...which HDD should i buy? &nbsp;RED? &nbsp;Black? &nbsp;Green?<br />
<br />
I am leaning towards RED but don't see any info on using them inside your PC.<br />
I do like keeping the PC on most, if not all, the time.<br />
<br />
Thanks<br />

Buying new drives for my internal storage

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
