The amount of SATA ports you need will depend on how many storage drives you plan to connect to your PC. Each drive connects to a single SATA port. Two SATA ports are generally reasonably sufficient for a basic build. However, If you need to connect more hard drives, you will need more SATA ports.
SATA has long been the industry standard for connecting storage drives ranging from hard disks to SSDs and optical drives. If you are new to building PCs, asking how many SATA ports you need is standard.
An average motherboard can easily have 4-6 SATA ports depending on its chipset and size. The amount of SATA ports you need primarily depends upon what you intend to accomplish.
For instance, if you are building an average PC for home use, then as mentioned earlier, 2 SATA ports should be sufficient.
On the other hand, if you are building a NAS PC with multiple storage drives, particularly in RAID configuration, you may need 6, 8, or even more SATA ports, depending on your large storage solution.

SATA Ports on the Motherboard
To connect hard drives to a PC, you need an interface. SATA is an interface that connects SATA SSDs, HDDs, and CD drives to your motherboard.
SATA stands for serial ATA, and it has many different versions. The most current version is SATA 3.0.
Each version is significantly better than its predecessor in terms of performance. The older SATA 2.0 had a speed of 3Gbps (375 MB/s), whereas the current version, i.e., the 3.0, has a max theoretical transfer speed of 6 Gbps (750 MB/s).
The transfer speed of the SATA ports matters a lot, particularly when installing SATA-based SSDs. A SATA SSD on a SATA 3 interface can have a transfer speed of about 550 MB/s. If you install the same on a SATA 2 port, it will operate at half the speed.
A typical hard disk generally has a transfer speed of about 200 MB/s; therefore, it would not matter much if you used this on a SATA 3 or SATA 2 interface.

Most motherboards, even the smallest ones with the Mini ITX form factor and featuring entry-level chipsets, i.e., an H series chipset for Intel and an A series chipset for AMD, easily feature at least 4 SATA ports.
You should consult your motherboard spec sheet to know the exact amount of SATA ports you have.

So How Many SATA Ports Do You Need?
The amount of SATA ports you need depends upon a lot of factors.
Essentially, a regular user would not require as many SATA ports as a professional wanting to create a NAS storage solution would require.
Anyhow, the following scenarios should better guide you.
For a Regular User
Here we assume a regular user has their desktop set for basic tasks like browsing the internet and doing light work like typing word processing.
A casual user will require one port for their primary hard drive. They may also need an optical drive for inserting CD drives into.
So, two SATA ports would be sufficient for regular home or office use. Finding a motherboard with two SATA ports is hardly an issue. Most motherboards, including entry-level chipsets like the Intel H series or the AMD A-series chipset, will have at least 4 SATA ports.

The Intermediate Users
An intermediate class of users may indulge in heavier tasks like video editing and photo editing.
As such, they may require a larger storage capacity and faster speeds for their primary boot drive.
So in a situation like this, you may have two hard drives for storing media and perhaps one SATA SSD drive (as your primary boot drive). You may also need a CD drive for recording your media.
We recommend an SSD as the primary drive for an intermediate user because it can give you a remarkable performance difference compared to a standard HDD.

You wouldn’t need a vast SSD since most larger files can be stored in two archival hard drives. The SSD’s primary job would be to have the OS and the ‘hot data’ or the project and the software you are working on.
For an intermediate user, notably an editor who works on professional software, we recommend at least 4 SATA ports for immediate and future expansion.
PCIe NVMe vs. SATA SSDs
Note that there is a difference between a PCIe-based NVMe SSD and a SATA-based SSD.
The NVMe SSDs use the much faster PCIe express to reach read speeds of about 3,500 MB/s on PCIe v3.0 and 5,000 MB/s on PCIe v4.0.
A typical SATA 3.0 SSD has speeds of only about 550 MB/s max.
However, the NVMe SSDs use the PCIe interface and thus cannot be installed on SATA ports. They instead use the M.2 slots, which use the PCIe lanes.
If you have an M.2 slot available, we recommend you ditch the SATA SSDs and go for an NVMe SSD in a heartbeat. If you choose this route, you will free up SATA ports that would have otherwise been used for SATA SSD.
Multi Drive NAS Users and Professionals
In this next category of users, we have people who want to leverage their SATA ports for more than two or three drives. This can be seen as a measure to improve the storage capacity of the computers or to create a personal media server.
Users who need to use multiple drive bays will often want some hard drives to be used as backups in case one or more of the hard drives they have installed fail.
So a setup for NAS, RAID configuration for mirroring the drives, and for professional backup, you may need a motherboard with as many SATA ports as possible.
For a NAS setup, particularly with RAID mirror configuration, we recommend at least 6 SATA ports. However, it is common for NAS pc to have as many as eight or more SATA ports.

Expanding the Amount of SATA Slots, You Have

What happens when you find that the SATA slots on your motherboard are no longer enough?
If you realize that you need extra HDDs or SSDs and have run out of slots, you can purchase a Storage Controller or a SATA Expansion Card somewhere down the line.
The SATA expansion card goes into the PCIe express slot. A few factors determine their size and price:
- How many SATA ports do they have
- The version of the SATA ports
- Whether they are RAID or non-RAID
For instance, an SATA expansion card with SATA 3 ports and RAID utility will be more expensive than a non-RAID expansion card with SATA 1 expansion ports.
This expansion card can be installed directly into the smaller PCIe slots. Because PCIe is much faster than SATA, you barely get a performance hit unless you use too many places on a multiplier card connected to a lower-performance PCIe slot.

When determining how many SATA ports you need, pay attention to your needs first so that you don’t end up purchasing a board with far more SATA ports than you need or one with fewer slots.
While there’s no big deal with having more than enough SATA ports, having fewer can be costly. So, to be on the safe side, ensure you take your needs into account.
A safe bet is to always go with three or more ports. This way, you could potentially use one for a SATA SSD for fast boot times, one for HDD for data storage, one for an optical disk drive, and the last as a spare for future use.
