One of the most common questions we get asked is how many SATA drives a user can connect to their PC. The answer, unfortunately, isn’t as simple as we would like it to be and depends on a few factors. In this blog post, we’ll go over everything you need to know about connecting multiple SATA drives to your PC.

The first thing to consider is your motherboard. In most cases, there are a limited number of SATA ports on a motherboard, usually four or six. If you want to connect more than four or six drives, you’ll need to use a SATA controller card. There are a few different types of SATA controller cards, but the two most common are internal cards that mount in an available PCI slot and external cards that connect via USB.

Internal SATA Controller Card

If you’re using an internal SATA controller card, it’s important to check the compatibility with your motherboard. Some motherboards have a limited number of PCI slots, so you’ll need to make sure there are enough free slots for the card and any other cards you might need (sound card, video card, etc.). Additionally, some motherboards have limitations on the type of PCI slots that can be used for SATA controller cards. For example, some motherboards only allow certain types of PCI slots to be used for SATA cards.

Once you’ve determined that your motherboard has enough free slots and is compatible with the SATA controller card you’ve selected, the next step is to install the card. This usually involves opening up your computer case and attaching the card to an available slot using screws. After the card is installed, you’ll need to hook up the SATA cables from the drives to the appropriate ports on the card.

External SATA Controller card

If you’re using an external SATA controller card, the installation process is usually much simpler. Most external cards come with all the necessary cables and simply need to be plugged into an available USB port. After the card is installed, you’ll again need to connect the SATA cables from the drives to the appropriate ports on the card.

Once everything is hooked up and installed, you should be able to use all of your drives without any issues. One thing to keep in mind, however, is that the maximum data transfer rate for SATA is limited to 150MB/s. This means that if you have multiple drives that you’re trying to use for high-speed data transfers (like video editing or gaming), you might not be able to take full advantage of their speeds.


There are a few advantages to using a SATA controller card:

  1. You can connect more drives than your motherboard supports. This is especially helpful if you have a lot of drives or if you need to use a mix of SSDs and HDDs.
  2. SATA controller cards usually come with their own software that allows you to manage and monitor your drives. This can be helpful if you’re trying to keep track of drive health or performance.
  3. Some SATA controller cards offer features like port multiplication, which allows you to connect multiple devices to a single port. This can be helpful if you need to connect more devices than there are ports on the card.


There are also a few disadvantages to using a SATA controller card:

  1. They can be more expensive than simply buying a new motherboard with more SATA ports.
  2. They can be tricky to install, especially if you’re not familiar with opening up your computer case and attaching components.
  3. Some motherboards might not be compatible with certain types of SATA controller cards.
  4. They can add another point of failure to your system. If the card fails, you might not be able to access any of your drives.

SATA controller cards can be a helpful way to add more SATA ports to your system, but they’re not right for everyone. They can be expensive and tricky to install, and they might not be compatible with your motherboard. If you’re not sure whether or not a SATA controller card is right for you, it’s always best to consult.
