Why migrate Windows 10 to new hard drive?

If you are struggling to open large files on your system or run various applications at the same time, and the Windows 10 operating system reads too slowly, it is a great choice to upgrade your computer from old hard drive to a new hard drive. This can be the most effective way to speed up your Windows 10 computer.

However, changing a new disk without OS installed will cost you lots of time and effort to reinstall everything from scratch, so you might wish to directly migrate Windows 10 from the old hard drive to the new one. Then, you don’t need to install the system after the migration, and you can start your computer directly from the new disk too.

Migrate Windows 10 to new SSD or HDD?

After deciding to transfer Windows 10 to new hard drive, now it is time to make a choice between SSD and HDD. Which of the two is the better choice? There’s no straightforward answer to this question. Each buyer has different needs, and you have to evaluate the decision based on your own requirements, budget, and preferences. Here we would like to introduce the difference between SSD and HDD to help with your decision.

▶ SSD-Solid State Drive: A kind of hard disk which is made by solid-state electronic storage chip and consists of the control unit (flash chip) and stipulation of interface, in function and usage and in appearance and size.

▶ HDD-Hard Disk Drive: It is the most basic computer storage, made up of magnetic tape with mechanical parts inside. They are larger and prone to damage.


SSD(Solid State Drive)

HDD(Hard Disk Drive)

Power Draw/Battery Life

Less power draw, averages 2 – 3 watts, resulting in 30+ minute battery boost

More power draw, averages 6 – 7 watts and therefore uses more battery


Expensive, roughly $0.50 per gigabyte (based on buying a 1TB drive)

Only around $0.15 per gigabyte, very cheap (buying a 4TB model)


Typically not larger than 512GB for notebook size drives; 1TB max for desktops

Typically around 500GB and 2TB maximum for notebook size drives; 4TB max for desktops

Operating System Boot Time

Around 22 seconds average bootup time

Around 40 seconds average bootup time


There are no moving parts and as such no sound

Audible clicks and spinning can be heard


No vibration as there are no moving parts

The spinning of the platters can sometimes result in vibration

Heat Produced

Lower power draw and no moving parts so little heat is produced

HDD doesn’t produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw

File Copy / Write Speed

Generally above 200 MB/s and up to 550 MB/s for cutting edge drives

The range can be anywhere from 50 – 120MB / s

File Opening Speed

Up to 30% faster than HDD

Slower than SSD

Magnetism Affected?

An SSD is safe from any effects of magnetism

Magnets can erase data

Scope of application

Applicable to indoor, no change in temperature, no shock and vibration equipment. It is widely used in military, IT industry,aviation and many other fields.

Applicable to outdoor, low temperature, high temperature, shipborne, automotive, airborne products, firewalls, robots, portable devices, military, etc. It is suitable for home use.

Now, you should have a better understanding of those two disks. Whatever hard drive you choose to contain the Windows 10 from the old hard drive, you will also need a professional OS migration tool.
