Usually, PCs and laptops have a single heart drive. The space these hard drive offers are more than enough for normal usages. But sometimes, a single drive may not be efficient enough for heavy usages. Adding a second hard drive to a PC can increase the amount of storage space. If you install multiple drives on your PCs, it can also help to drive down the costs of buying more PCs. Installing multiple hard drives can offer better data security. Backing up data will become faster and easier. Multiple hard drives in your PCs can also make your PC faster by optimizing Windows Server performance. Adding a second-hand drive can be a little difficult for many users. So in this article, we will give you a full guide of how you can easily add a second drive to Windows Server 2019/2016/2012 (r2)/2008, etc.

1. Tips to Purchase or Select a Second New Hard Drive/SSD

If you are buying a second hard drive for Windows Server and are confused about which hard drive will be the best for your PC, you need to read these tips. The first thing to consider before buying a second hard drive is whether you need a solid-state drive (SSD) or not. Here are some tips for Windows Server users on selecting a second drive for adding to their Server machines.

Purposes - Usage Purposes

the first thing to remember before adding a second hard drive to your PC is why you need another hard drive. You may not necessarily need a second hard drive if you are a normal PC user (i.e., students). However, if you're a gamer or content editor or if your work requires a second hard drive, only then should you buy one. So you need to buy a second hard drive as per your requirement.

Storage Capacity

Before you go to the store and buy a second hard drive, you need to think about your storage capacity needs. Nowadays, most hard drives come in capacities from 250 gigabytes to several terabytes (1000GB = 1TB). If you have several big files and videos, you may want to buy a 1TB storage hard drive. But if you don't have many files, you can go for a small storage hard drive.


The cost of a hard drive is another thing to consider. Hard drives are usually very expensive, and they come in different ranges. So how to decide which one is the best? Divide the drive's price by its storage capacity and buy it for price-per-gigabyte.

Disk size/weight 

You also need to consider the size and weight of the hard drive before adding a second hard drive to your PC. If you buy a disk that is too heavy, it will also make your PC a lot heavier.

Read/write speed

Making your PC faster than a faster external hard drive is a better option. It will also make Read/write speed faster to copy your files and paste them easily. Usually, a hard drive comes with 5,400 rpm, but there are many faster models in the market.

2. How to Add Second Drive to Windows Server Computers

There are two steps in the process of adding a second hard disk to a Windows PC. Firstly, you have to install the drive inside your PC physically, and then you need to set it up from windows so that OS can recognize and use it. When adding a second hard drive to your PC, these are all the things you need:

An open drive bay, A second hard drive or SSD, A SATA data cable, A screwdriver, An open SATA data connection on your motherboard, A SATA data cable, An available SATA power connector.

Once you have all the necessary tools, simply follow the below instructions to add a second hard disk to your PC.

Step 1. First, close your PC and unplug it to avoid getting any discharging static. Then open up the case using a screwdriver.

Step 2. Look for an open drive bay.

Step 7. Check if all the plugs are placed correctly or not, then close up the PC case and turn on your PC.

This is the way you add a second hard drive to your PC. Now you need to set up the second Hard drive from your Windows for the OS to recognize.

3. Initialize New Hard Drive in Windows Server

After installing a second hard drive to your PC, it doesn't show up in your system right away. You need to add a drive letter or initialize it so that you can use it. One thing to note before Initializing a disk is this process can erase everything from the disk.

Here are all the steps of Initializing a new disk using Disk Management.

  • Go to the Windows button and click on the search box. Then type Disk Management and search.
  • When the window opens up, choose Run as administrator and click on YES.
  • Locate the disk you wish to initialize, then right-click on it > Initialize Disk.
  • A Initialize Disk dialog box will show up. Click on 'ok'.
  • After that, right-click on the unallocated space in the drive and then choose New Simple Volume.
  • Click on Next and mention the size of the volume, then again click on Next.
  • You can name the drive and again click on next.
  • Then simply follow the window's instructions and finish it.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
