How to Check What Type of SSD Is in Your PC?

Windows can usually tell you whether your PC uses an SSD or hard disk without opening the case. You can also find the drive’s model, manufacturer, connection type, and when the system reports it correctly whether an M.2 SSD uses SATA or NVMe.

The best method to check what type of SSD in your PC depends on what you need to know:

• SSD or HDD: Task Manager or Drive Optimizer
• Manufacturer and model: Device Manager
• Which physical disk contains C:: Disk Management or PowerShell
• SATA, NVMe, health, and S.M.A.R.T. details: PowerShell, CrystalDiskInfo, or HWiNFO

If you are not sure what the distinction means yet, our guide to how solid-state drives work explains why the two behave so differently.

Check whether the drive is an SSD or HDD in Task Manager

Task Manager is usually the fastest built-in method in Windows 10 and Windows 11.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Select Performance.
3. Choose Disk 0, Disk 1, or another disk in the left panel.
4. Look for the drive type near the top-right or below the disk name.

Windows may label the device as SSD or HDD. If your PC has multiple drives, select each disk separately because one computer can contain both types.

Task Manager is useful for a quick media-type check, but it may not show the exact model, interface, or protocol. It also identifies physical disks by number, not necessarily by the drive letter you use in File Explorer.

Use Drive Optimizer to display the media type

Drive Optimizer, previously called Disk Defragmenter, provides another simple way to check whether a volume is on an SSD or HDD.

1. Press Windows + R.
2. Type dfrgui.
3. Press Enter.
4. Check the Media type column.

The result may show Solid state drive or Hard disk drive. This method is particularly useful when Task Manager does not clearly display the type.

Drive Optimizer usually lists volumes rather than giving you every hardware specification. If you need the exact drive model or want to distinguish between SATA and NVMe, use one of the methods below.

Find the SSD model and manufacturer in Device Manager

Device Manager can reveal the exact name reported by the storage hardware.

1. Right-click the Start button.
2. Select Device Manager.
3. Expand Disk drives.
4. Read the model name listed for each drive.

A listing might include a manufacturer and model number, such as a product family followed by a capacity or series code. Copy the complete model name into the manufacturer’s website or a reliable specification database if Windows does not identify the interface directly.

Device Manager does not always label a device as an SSD. A model name can tell you more than a simple “SSD” label, but you may need to look up the exact model to confirm its interface, protocol, and physical format.

Match your C: drive to the correct physical disk

The C: drive is a logical volume or partition. It is not itself a physical SSD. If your computer has more than one disk, use Disk Management to determine which physical disk contains it.

1. Right-click the Start button.
2. Select Disk Management.
3. Find the volume labeled (C:).
4. Note the physical disk number shown below it, such as Disk 0.
5. Match that disk number with the corresponding entry in Task Manager or Device Manager.

This matters when, for example, Windows is installed on an NVMe SSD but your files or games are stored on a separate SATA SSD. A drive letter alone cannot tell you which storage technology is in use.

Disk Management also shows the partition layout and capacity, but it generally does not identify whether an SSD is SATA or NVMe.

Check the SSD type with PowerShell

PowerShell can report physical-disk properties directly. Open Windows Terminal or PowerShell as a normal user and run:

Get-PhysicalDisk | Select-Object FriendlyName, MediaType, BusType, Size

The important columns are:

• FriendlyName: The name reported by the drive or storage controller
• MediaType: Usually SSD or HDD when Windows receives this information
• BusType: The connection type, such as SATA or NVMe
• Size: The reported capacity in bytes

To see the model and disk number recognized by Windows, run:

Get-Disk | Select-Object Number, FriendlyName, SerialNumber, BusType, Size

To identify the physical disk containing the Windows C: volume, run:

Get-Partition -DriveLetter C | Get-Disk

PowerShell results depend on the storage controller, driver, and firmware. If a field is blank or says Unknown, that does not necessarily mean the drive is defective. It means Windows is not receiving that property through the current hardware and driver configuration.

These four terms describe different things, and starting with what SATA is makes the rest of the terminology fall into place.

Understand the difference between SSD, SATA, NVMe, and M.2

These terms describe different aspects of a drive:

Term	What it describes
SSD	The storage technology using flash memory rather than spinning magnetic platters
SATA	A connection standard commonly used by 2.5-inch SSDs and some M.2 SSDs
NVMe	A storage protocol designed for flash storage, commonly operating over PCIe
M.2	A physical form factor for a small expansion drive
PCIe	A high-speed interface used by most NVMe SSDs

An M.2 SSD is not automatically an NVMe SSD. M.2 drives can use either SATA or PCIe/NVMe. For an upgrade, confirm the interface and protocol rather than relying on the M.2 label alone.

A 2.5-inch SSD is commonly SATA, while an M.2 drive requires more careful verification.

Once you know which one you have, our comparison of NVMe vs SATA SSD explains whether the difference will actually show up in your workload.

Check whether an M.2 SSD is SATA or NVMe

Start with PowerShell:

Get-PhysicalDisk | Select-Object FriendlyName, MediaType, BusType

If BusType reports NVMe, the drive uses the NVMe protocol. If it reports SATA, it is a SATA-connected drive.

You can also check the model in Device Manager and search for the exact product documentation. The manufacturer’s specification page should identify whether the drive uses:

• SATA III
• PCIe 3.0 or PCIe 4.0
• NVMe
• A particular M.2 key or size

Do not identify the drive solely from its appearance. Two M.2 drives can have the same physical shape while using different interfaces. This distinction is important because a computer or motherboard may support only one type in a particular M.2 slot.

Use a diagnostic utility for deeper drive details

If Windows tools provide incomplete information, a reputable diagnostic utility such as CrystalDiskInfo or HWiNFO can expose additional details.

Depending on the drive and controller, these tools may show:

• Exact model and firmware
• Interface and transfer mode
• SATA or NVMe classification
• Drive temperature
• Power-on hours
• S.M.A.R.T. attributes
• Health indicators
• Serial number

Download utilities from their official websites or trusted publisher pages. Diagnostic programs can report more information than Task Manager, but the displayed interface may still reflect the storage controller rather than the physical connection in a simple way.

For a replacement drive, use the reported model number and the manufacturer’s specifications as the final check.

What to do when Windows shows a generic drive name

If Device Manager shows a generic name or PowerShell reports Unknown, try these steps:

1. Check the drive in Task Manager for a basic SSD or HDD label.
2. Run dfrgui and check the Media type column.
3. Install current chipset and storage-controller drivers from the PC or motherboard manufacturer.
4. Check the model in BIOS or UEFI.
5. Use CrystalDiskInfo or HWiNFO to inspect the device.
6. Search the exact model number if one is visible anywhere in Windows.

BIOS and UEFI menus vary by manufacturer. Storage information may appear under Storage, NVMe Configuration, Advanced, or a similar heading. If software cannot identify the drive, physically inspecting its label is another option, but opening a laptop or desktop may affect warranty coverage or risk damaging a connector.

Choose the method that matches your goal

What you need to know	Best first method
Is the drive an SSD or HDD?	Task Manager
Is a particular volume on an SSD?	Drive Optimizer
What is the manufacturer and model?	Device Manager
Which disk contains C:?	Disk Management or PowerShell
Is the drive SATA or NVMe?	PowerShell, diagnostic utility, or model lookup
What is the drive’s health?	CrystalDiskInfo or HWiNFO
Windows cannot identify the drive	BIOS/UEFI, diagnostic utility, or physical label

For a basic check, start with Task Manager. If you are preparing an upgrade, continue until you have confirmed the exact model, capacity, form factor, interface, and protocol. That prevents the common mistake of buying an M.2 drive that physically fits but is not electrically compatible with the available slot.
