Knowing the type of hard drive you have in your computer is important for several reasons. The main types of hard drives are traditional hard disk drives (HDD), solid state drives (SSD), and hybrid drives. HDDs and SSDs have significantly different performance characteristics that impact the speed and responsiveness of your computer. HDDs also have more potential failure points due to their mechanical nature. Understanding your hard drive type helps you know what to expect in terms of performance, lifespan, and maintenance needs.
HDDs use spinning magnetic disks to store data. They have high capacity but slower performance, especially for random access tasks. SSDs store data on flash memory chips and have no moving parts. They are much faster than HDDs for most operations but more expensive per gigabyte. Hybrid drives combine HDD and SSD technology in the same unit to balance speed, capacity, and cost.
Knowing your exact hard drive model also helps determine the age, interface type, max speed, cache size, and other specifications. This in turn helps you optimize your system settings and recognize when an upgrade may provide a worthwhile boost in speed or capacity. With a variety of tools available to identify your hard drive type, it only takes a few minutes to better understand a key component empowering your digital life.
Check Manufacturers Labels
One of the easiest ways to identify your hard drive’s model is to look for any labels directly printed on the drive itself or its packaging. Hard drive manufacturers like Seagate, Western Digital, Toshiba, etc. will usually label the drive with some basic specifications.
Look for a sticker or engraving on the top or bottom of the actual hard drive that lists details like:
- Interface type (SATA, IDE, etc.)
- Capacity (500 GB, 1 TB, etc.)
- Spindle speed in RPMs (5400, 7200, etc.)
- Cache size
- Model number
- Serial number
The box or packaging the drive came in likely lists the same information. Checking these manufacturer labels can provide all the basic details about that specific hard drive model and its specs.
Check Disk Utility
Most operating systems like MacOS and Windows come with built-in disk utilities that can provide detailed information about your hard drive. On Mac, open the Disk Utility app located in Applications > Utilities. Select your hard drive from the left panel, then click the Info button at the top.
This will show the drive name, format (MacOS Extended, ExFAT, etc.), capacity, partitions if any, and S.M.A.R.T. status which indicates if hardware issues are detected.
On Windows 10 and 11, you can access the Disk Management utility by right-clicking the Start menu and selecting Disk Management. This also shows the drive name, format, capacity, partitions, and any detected issues. Using these built-in disk utilities is a quick way to get a snapshot of your hard drive’s details and health status without any additional software.
Check System Profiler
On Mac computers, you can use the System Profiler utility to get detailed information about your hardware, including the type of hard drive. To open System Profiler, go to Finder > Applications > Utilities and double click on System Profiler.
In the System Profiler window, click on the Storage category on the left. This will show details about all the storage drives connected to your Mac. Look for the drive you want to check under the Volume Information section. Here you can find the drive type (HDD or SSD), interface, capacity, and other technical details.
For example, if you see “Media Type: SSD” it means that drive is a solid state drive. Whereas “Rotation Rate: 5400 rpm” would indicate a traditional hard disk drive. The System Profiler provides the most comprehensive way to identify drive types on a Mac.
You can also get quick access to System Profiler from the Apple menu. Click the Apple icon in the top left corner, select About This Mac, and then click System Report. This opens the System Profiler app where you can view storage drive details.
Check Device Manager
On Windows, you can use Device Manager to view all connected devices and determine if you have a HDD or SSD.
To open Device Manager on Windows, press Windows Key + R to open the Run dialog box. Type “devmgmt.msc” and press Enter. This will open the Device Manager window.
In Device Manager, expand the “Disk drives” category. This will display all your connected hard disk drives. Look at the drive model names to determine if you have a HDD or SSD.
HDDs typically have model names that reference a rotational hard disk like “WDC WD10EZEX-08M2NA0” or “ST1000DM003-1CH162.” SSDs usually have names that reference solid state or flash memory like “Samsung SSD 850 EVO 500GB.”
You can also look at the drive type column in Device Manager. HDDs will show a “Hard Disk Drive” type while SSDs will be listed as “Solid State Drive.”
So by opening Device Manager and checking the disk drive information, you can easily determine whether your Windows PC has a HDD, SSD, or both installed.

Check SMART Data
One of the best ways to identify your hard drive type is to check the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data using tools built into your operating system. S.M.A.R.T. provides information on drive health and performance by monitoring different attributes like read error rate, start/stop count, and total bytes written.
By viewing the S.M.A.R.T data, you can distinguish between an HDD and SSD drive. HDDs will show attributes like start/stop count and seek error rate that relate to physical head movements. SSDs will show attributes measuring wear leveling and total bytes written to memory cells. Tools like Hard Disk Sentinel make it easy to read S.M.A.R.T. data and identify the drive type.
On Windows, you can access S.M.A.R.T. data using the command prompt or a utility like CrystalDiskInfo. On Macs, Disk Utility has a S.M.A.R.T. status section when viewing drive info. Checking these stats and attributes offers a reliable way to determine if your drive is an HDD or SSD.
Check Drive Partitions
Most hard disk drives (HDDs) have multiple partitions, whereas solid state drives (SSDs) typically have a single partition containing all the drive’s storage space. You can check how many partitions your drive has using your operating system’s disk utility program.
On Windows, open Disk Management and look at the graphical view of your disks. HDDs will often show multiple partitions, while SSDs show a single large partition taking up the full capacity of the drive.
On macOS, open Disk Utility and select the drive in question. Click the Partition tab to view the partitions on that drive. Again, HDDs typically have multiple partitions listed here, while SSDs have a single partition.
Having multiple partitions used to be more common on HDDs to organize files and optimize performance. With modern SSDs, a single partition works well and partitions are less necessary. So the number of partitions can be an easy way to identify HDDs vs SSDs. Just be aware that some users may customize partitions on either drive type.

Check Drive Noise
One of the key differences between a traditional hard disk drive (HDD) and a solid state drive (SSD) is the noise they make during operation. HDDs contain moving mechanical parts like platters and read/write heads, which produce audible spinning and clicking sounds as data is accessed. In contrast, SSDs have no moving parts and are completely silent during operation.
If you hear any spinning or mechanical noises coming from your computer’s drive, it’s a telltale sign you have a HDD installed. SSDs operate silently even under heavy load. As this Tom’s Hardware forum post notes, “SSDs make no noise. Period. Nothing to ‘move’.”
Some exceptions are that a failing SSD may make clicking or buzzing noises, and some SSDs have an internal cooling fan that produces minimal noise. But in general, if the drive makes audible spinning or mechanical sounds during normal operation, you can be certain it’s a HDD rather than SSD.
Check Drive Price
One way to determine if your hard drive is a traditional HDD or a solid state drive (SSD) is to check the price per gigabyte (GB). HDDs are generally much cheaper in terms of cost per GB compared to SSDs.
According to SSD vs HDD – Difference Between Data Storage Devices – AWS, data storage on an SSD can cost $0.08–0.10 per GB, while storage on an HDD costs around $0.03–0.05 per GB. So if you paid around 3-5 cents per GB, it is likely an HDD, while 8-10 cents per GB indicates an SSD.
As noted in SSD vs. HDD: Which should go in your PC?, a 1TB HDD may only cost $30 while a 1TB SSD would cost $60. The significantly lower price per GB is a strong indicator that the drive is a traditional HDD rather than a pricier SSD.
If you are unsure or don’t know the exact price paid, you can use the large price difference as a clue. In general, if your drive was very inexpensive in terms of dollars per GB, it is likely a traditional HDD rather than an SSD.
Conclusion
In summary, there are several key ways to identify what type of hard drive you have in your computer or laptop. First, check any manufacturer labels on the drive itself for details like model number, specs, and serial number. These can give you specific information about the make, capacity, and connectivity of your drive. You can also check your operating system’s Disk Utility or System Profiler on Macs, or the Device Manager in Windows, to get information about the drive’s interface and other attributes.
Examining the drive’s partition structure, noise profile, pricing, and SMART data can provide additional clues. Older, louder drives with multiple partitions are more likely to be traditional hard disk drives, while newer, silent SSDs will be identifiable by their higher cost per gigabyte and solid state specifics in SMART data.
It’s useful to know precisely what kind of hard drive you have because it affects performance, lifespan, and optimal use cases. HDDs and SSDs have different strengths and weaknesses – for example, HDDs offer more storage capacity while SSDs are much faster and more reliable. Identifying your exact drive type helps you get the most out of your computer system.
