Can desktop hard drive be used for laptops

Technologically all hard drives are just similar whether installed in desktop or laptops. They work as spinning magnetic platters that record and store data though they are two different types, HDD and SSD.

Multiple types of connection interfaces vary between laptops and desktop in old times. But today the Serial SATA type is dominating both markets with distinguishing factors like space, speed, and physical size.

If you want to know can desktop hard drive be used for laptops or not then the answer is NO, they cannot fit in the laptops. Make it simple, desktop HDD is 4 times larger (3.5 inches) than a laptop’s HDD which is 2.5 inches. There is no way to install the big hard drive in your laptop because of space. Though, you can use USB flash drives to move data or window installation.

Are laptop and desktop hard drive the same?

The hard drive means, a metallic disk spun by a motor making sectors of the disk pass under the head to read and write when move. The desktop system works on this principle of polarization whereas laptop’s HDDs are also not different.

But the only outer shell of HDD is smaller and uses less electricity, so the read and write speed is lower than a desktop computer.

Expensive laptops like Notebook uses advanced power scheme to cut down the consumption and protect the drive against shocks and falls. As some laptops recognizing falling and put the head at a safe position before impact to save from loss.

Factors that not permit using desktop HDD in the laptop

You cannot install the HDD of desktop in laptop but can connect it to the laptop to recover data or transfer files. Through a special box (concerning the interface of the laptop) to connect by USB cable. Undermentioned few factors do not allow the desktop hard drive to be used for laptops:

Physical size

Old model desktop computers used to have 5.25 inches hard drive but today with the advancement of technology they primarily use 3.5-inch drives. For increasing the drive’s storage space this size allow it for several internal platters to write and read data.

Because desktop HDD are heavy and thick, so cannot be used in laptops. The laptop’s hard drive is slim, light and uses less energy because it runs on battery.

Even though there are iPods that use the 1.8-inch hard drive and other ultra-thin laptops or notebook. So it is impossible to fit the desktop hard drives in laptops.

Storage space

The larger size means big storage space and enough room. So, the laptop’s drive has a lower capacity for storage with physical thinness.

High-end PC have 3.5-inch hard drive boast 4TB of storage whereas the laptops have only 1 TB maximum. Because the laptop’s hard is thin with smaller platters to read and write data and have less storage space according to the size.

However, every year increasing the storage space in laptops but the physical size until not providing desktop drive space.

Hard drive speed

Few expensive system’s HDD platters spin faster like 10,000 RPM to read & write data. Whereas the majority desktop HDD runs 7,200 rotation per minute.

Many laptops drive run slower at 5,400 RPM to maintain the noise level and power use or not to heat the laptop. That’s why the decreased rotation affects the speed of the system because it has to spin for longer to reach a piece of data. Though some of the laptops models installed HDD of 7,200 RPM have no issue with speed.

Solid State Drives (SSD)

Solid states drive replaced the hard drives of computers and laptops from the previous years. Now the improved SSDs have less noise because the platters are replaced with the data chips which remove noise and heat by HDD.

These SSDs run faster than even 10,000 RPM hard drives and much expensive as well. Some of the desktops computers have both drives as small SSD for frequent-used data and large drive for big storage capacity.

So as the laptops cannot fit two drives. Some models offer hybrid drives that have large storage with the addition of SSD used for caching on the laptops.

Compatibility

The fact is that you cannot fit your desktop drive in the laptop internally, but you can still connect it using an external enclosure via USB or SATA cable. Consequently using laptops hard drive on the desktop with an enclosure or using a mounting bracket to install them internally. Because some desktop systems include 2.5-inch drive bays since the SSDs come with the size.

Connecting the desktop HDD to a laptop via USB ports

You cannot install the desktop HDD in laptops but you can connect that to your laptop through USB ports to transfer your data and files. Concerning the laptop’s interface for the connection, you will need a special box which can be of different types, such as:

3.5-Inch IDE to USB 2.0 External Enclosure

This box is used for an average 3.5-inch hard drive with IDE interface to connect it to the USB 2.0 port. The data transfer speed of this external enclosure is under 20-35 MB/s. Click here to buy online

3.5 Inch IDE to USB 3.0

This is the same box with the same functionality, but the data transferring speed is higher.

USB 3.0 to SATA III Hard Drive Case

This portable box looks like a rectangular box and bigger than the hard drive. You can open the box and put the hard drive inside then close and connect. You need a power supply to this box and a USB cable to connect it to the laptop. Buy now

Now you are all done with the hard drive to connect it to any devices via USB cable to USB ports.

Now you can transfer the data of the hard drive to the laptop. So the HDD can work with the laptop by connecting it externally via USB cable but not in the laptop.

Why is my HDD not being recognized in a laptop?

If you facing issues in your laptop system that does not recognize the HDD then check first if you may need to install drivers for the box. Usually, windows automatically install it but if the box is non-standard you may have a problem.

Go to the ‘Device Manager’ and see if there are drivers for your device or you can even search online. Make sure there should be no yellow exclamatory marks prompt.

While in Windows 10 which usually installs itself the driver of the connected device but in case go to the ‘Disk Management’. Check if the hard drive you externally connected to the laptop is shown there or not. If it is there then you should change the drive letter or formatting it can make it work.

Conclusion

If the only reason for connecting the desktop hard drive to the laptop is to transfer files then you do not need to hang HDD to it all the time. You can just connect the PC and laptop through a local network and move data. You can do it by connecting cable but both must have network interface cards to transfer files.

If you work or play games on the desktop drive then you can connect it through the external hard drive enclosure via USB cable. The enclosure is used for the long term and regular work on the external hard drive.
