How to Install a Second SSD

This article explains how to install a second SSD into a Windows PC. It covers the necessary parts, the physical installation, and the initialization of the drive using Windows Disk Management. This information pertains to Windows 10, 8.1, 8, and 7.

Preparation for Installing a Second SSD

Installing a second SSD in a Windows PC is a two-step process. First you physically install the drive inside the PC, and then you set it up using the Windows Disk Management utility for the operating system to recognize and use it.

Here's what you need if you want to install a second SSD in your PC:

• An open drive bay in the computer
• An open SATA data connection on the motherboard
• An SSD drive
• A screwdriver to open the case and secure the drive in place
• A SATA data cable
• An available SATA power connector
• An adapter if the SSD will be installed in a bay meant for a 5.25-inch drive

Of these items, the most important are an open drive bay and an open SATA data connection on your motherboard. Most computer cases come with a number of open bays, and most motherboards have a number of SATA connections for SSDs and peripherals like Blu-ray drives, but you should check that you have space before investing in a new SSD.

If your motherboard doesn't have any available SATA ports, you can buy a SATA controller that plugs into a PCI or PCIe slot. Similarly, you can use a Molex adapter or SATA power cable splitter if you're out of SATA power connections.

How to Install a Second SSD in Your Windows PC

Files pile up over time. Eventually, you'll be faced with deleting old files or using a secondary storage device. The easiest way to add storage to your PC is to attach an external drive to your PC and be done. However, if your computer case has the room and you have all the necessary components and tools, you can install a second SSD.

Here's how to install a second SSD in a PC:

1. Unplug your PC from power, and open up the case.

2. Locate an open drive bay.

   Your case may have one or two different drive bay sizes in addition to peripheral bays. If you don't have any 2.5 inch drive bays available, purchase a 2.5 to 5.25 inch adapter for your SSD and use a 5.25 inch bay.

3. Remove the drive caddy, and install your new SSD into it.

   Some cases don't have drive caddies. You may need to slide your drive directly into the bay and screw it in place, or there might be built-in fasteners that you twist or flip. Consult the owners manual that came with your case if you can't figure it out.

4. Install the caddy back into the drive bay.

   Depending on your case, the caddy may snap into place automatically, or you may have to use a fastener of some sort.

5. Locate a free SATA data cable port on your motherboard, and install a SATA data cable.

6. Locate a free SATA power connector.

   Use a Molex to SATA power adapter or a power splitter if you don't have a free SATA power connector.

7. Plug the SATA power and data connectors into your SSD drive.

   The power connector is the longer of the two connectors on your SSD. Note the orientation of the L-shaped connectors, and be careful to install the connectors in the correct orientation.

8. Carefully verify that all of the cables are seated securely, and make sure you didn't accidentally unplug anything or knock anything loose.

9. Close your case up, connect everything back up, and turn on your computer.

How to Initialize a New SSD in Windows

Once you've successfully installed your second SSD and plugged everything back in, it's time to turn on your PC and make sure everything works. If Windows doesn't recognize any of your drives or peripherals, power down and check for any loose or unplugged wires. If everything is in working order, then you can go ahead and set up your new SSD.

By default, Windows will see and recognize your second SSD, but it won't be able to use it for anything. Before you can actually use it, you have to initialize and then format it for use with Windows. After completing this process, your new SSD will be available to save new files and transfer old files from your original drive to free up space.

Here's how to set up a newly installed SSD in Windows:

1. Navigate to Control Panel > Disk Management.

   In Windows 7, click the Start button, right click Computer, and choose Manage to access Disk Management.

2. If prompted to initialize the disk, select GPT (GUID Partition Table) and click OK.

   If you're using Windows 7, choose MBR (Master Boot Record).

3. If the setup wizard starts automatically, skip to step 5. Otherwise, scroll the disk management window until you find your new SSD.

   You can easily identify your new SSD as it will be the only one that is unallocated.

4. Right click, and select New Simple Volume.

5. Click Next.

6. Make sure the two numbers match, and click Next.

   If you want to make multiple partitions on this one drive, enter the desired partition size instead of matching the numbers.

7. Select a drive letter if you don't like the default one, and click Next.

8. Use the NTFS file system unless you have a reason to do otherwise, leave the allocation unit size as it is, enter a volume label if you desire, and click Next.

9. Verify the information, and click Finish.

10. Your second SSD is now ready to use.
