Figuring out the size of a SATA drive you have can be important for upgrading or replacing it. There are a few quick ways to determine the capacity of your SATA drive.
Check Drive Label
One of the easiest ways is to simply look at the label on the top or bottom of the physical SATA drive. Drive manufacturers will typically list the storage capacity, model number, serial number, and other specifications right on the drive label. This allows you to quickly see the size without having to install it in a computer.
For example, a 3.5″ SATA drive may have a label that states “1TB” or “2TB”, clearly indicating the capacity. Similarly, a 2.5″ laptop SATA drive may be labeled as “500GB” or “1TB”. So if you can physically see the drive label, check it for the listed capacity.
Use Drive Utility Software
If the SATA drive is already installed in your desktop computer or laptop, you can use drive utility software to determine the size.
On Windows, a couple options include:
- File Explorer – Right click the drive and select Properties. The total capacity will be shown.
- Disk Management – Right click the Start menu and select Disk Management. Find the disk and look at the number for total size.
- Third party tools like CrystalDiskInfo – Will show make, model, capacity, health status and other drive details.
On Mac OSX, options include:
- Finder – Select the drive and press Command+I. Look at the capacity size.
- System Information – Open System Information via Spotlight. Select Storage and it will list all drives and capacities.
- Third party tools like DriveDx – Will show SMART drive status, health, capacity and other details.
Using one of these drive utilities can quickly tell you the size without having to open up the computer case itself.
Boot Into BIOS Setup
If the drive is installed in a desktop computer, you can boot into the system BIOS setup screen to identify the drive capacity. Upon booting the computer, enter the BIOS setup, typically by pressing the Delete key, F1, F2 or other key during the initial start. Once in the BIOS, look for the storage information for installed drives.
There will often be a dedicated storage or hard drive settings page that lists out the make, model, capacity, and other details of internal drives. Consult your motherboard manual for how to access the BIOS and navigate to the drive info page.
Remove Drive and Use External Enclosure
Another option is to physically remove the SATA drive from the computer and insert into a USB external drive enclosure or dock. This allows you to then connect it to another system as an external drive and view the properties or details in the operating system.
For example, you could remove a 3.5″ desktop drive and insert into an external dock. Or remove a 2.5″ laptop drive and put it into an external USB enclosure. Then plug it into another computer via USB and open the drive properties or utility software to identify capacity and other information.
Identify via SMART Data
SMART (Self-Monitoring, Analysis and Reporting Technology) is a monitoring system included in drives to report health status and other details. Using SMART data tools can help identify drive information like capacity, model, serial number and more.
On Windows, tools like CrystalDiskInfo can read SMART data from the drive when installed internally or externally via USB. On Mac OSX, DriveDx and Smartmontools can fetch SMART reports to identify drive details.
The raw SMART data report will include the user capacity of the drive, helping to determine the overall size.
Connect to Another Computer
If you want to quickly determine the drive size without opening up a computer case, you can simply connect the drive to another desktop or laptop system externally. This could be using a USB enclosure, dock, or SATA to USB adapter cable.
Once connected externally, the operating system file explorer can display the drive capacity. This allows hot-swapping to quickly read drive details from another system without internal installation.
Conclusion
Identifying the capacity of a SATA drive is possible through several methods. If already installed internally, use utility software like file explorer, Disk Management or a third party tool to check capacity. If not yet installed, look for a label with size details printed on the drive itself. Other options include checking BIOS setup, connecting externally to a different computer, or utilizing SMART data to extract the user capacity of the drive.
Knowing the size of your SATA drive is important when purchasing a new drive or upgrading the storage in your desktop computer or laptop. Following the simple steps outlined above will allow you to accurately determine the capacity to ensure you get the right SATA drive for your system.

| Connect to Another Computer | Hot swap the drive to a different system externally to determine size |
Related Questions
How can I check SATA hard drive model number?
To identify the model number of a SATA hard drive, you can check the label on the drive itself for details like make, model, and serial number. If the drive is installed in a computer, use utility software like Disk Management on Windows or System Information on Mac to get model details. SMART data tools can also read and report hard drive model information.
What is the difference between SATA and SSD?
SATA is an interface standard for connecting drives to a computer, while SSD stands for Solid State Drive, a type of drive. A SATA SSD uses the SATA interface to connect an SSD to a computer, while a standard SATA drive has spinning platters instead of flash storage used in an SSD.
How can I tell if a hard drive is SATA or IDE?
You can tell the difference between a SATA and IDE hard drive by the interface connectors. SATA drives use a small, flat 7-pin or 15-pin connector, while IDE drives use a large 40 or 80-wire ribbon cable connector. The SATA data cable is smaller and more flexible compared to the wide, flat ribbon cable used for IDE drives.
What are the different SATA versions and speeds?
SATA has gone through several revisions with varying interface speeds:
- SATA I – 1.5 Gbps (150 MB/s)
- SATA II – 3 Gbps (300 MB/s)
- SATA III – 6 Gbps (600 MB/s)
- SATA Express – Up to 16 Gbps (1969 MB/s)
Newer SATA versions are backwards compatible, but maximum speed depends on both drive and host controller capabilities.
Can I use any SATA hard drive model with my computer?
Generally, any modern SATA drive should work fine as they use the same interface connectors. However, you’ll want to match the drive physical size (2.5″ or 3.5″) and storage capacity needed. Check your computer manual for drive compatibility to be sure. Watch for maximum drive height clearance if installing in a slim desktop or laptop.
How do I securely erase data from a SATA hard drive?
To securely erase a SATA hard drive, you can use drive wiping software that overwrites all data with zeros or random data. On Windows try DBAN, Active@ KillDisk or SecurAble. On Mac use the disk utility Secure Erase feature or a tool like Secure Eraser. Physically destroying the drive platters also guarantees secure data destruction.
Can I convert an old IDE drive to use SATA?
There are IDE to SATA converters available that allow an IDE drive to plug into a SATA controller, but not the other way around. The drive itself remains IDE, but the converter has a SATA connector to allow compatibility. Performance is limited to IDE speeds rather than SATA though.
How do I clone a SATA hard drive to an SSD?
To migrate your data from a SATA hard drive to a new SATA SSD, use drive cloning software like Macrium Reflect, Acronis True Image, Clonezilla or Mac SuperDuper. Connect both drives, then run the cloning app to copy partitions or the entire drive contents from old to new. Adjust partition sizes to fit the SSD space.
Tips for Identifying SATA Drive Size
- Double check the label on the physical drive for capacity details
- Use the operating system explorer tools to view properties
- Check system BIOS drive settings for model, capacity and other details
- Leverage SMART data capabilities to report drive specifications
- An external dock or enclosure can quickly connect the drive to another system
- Match the drive form factor and size needed for your computer
- Newer connectors don’t always mean faster performance, verify actual SATA version speed
