To know how to choose the right size of hard drive for your laptop is very important. When you try to build a laptop by yourself or upgrade hard drive, you may wonder: what size hard drive do I need for my laptop?

How to choose laptop hard drive size? Actually, it is not a difficult question to answer. You just need to be aware of some basic knowledge about how to pick a right-size laptop hard drive. And then learn how to manage the hard drive space flexibly and reasonably.

Hard Drive Physical Size

As for hard drive physical size, hard drives come in two main sizes--"3.5 inch", and "2.5 inch"--which are technical classifications that refer to the width of a hard drive's platter, but not the full dimensions of the hard drive unit itself.

  • 5 inch drives are 146 mm long, 101.6 mm wide, and either 19 or 25.4 mm tall.
  • 5 inch drives are 100 mm long, 69.85 mm wide, and either 5, 7, 9.5, 12.5, 15, or 19 mm tall.

Generally speaking, 3.5 inch drives are used in desktops and 2.5 inch drives are used in laptop computers. If you want to use a 2.5 inch drive in a desktop, you typically need a special bracket to fit it in a 3.5 inch drive bay.

After knowing the laptop hard drive physical size, the storage capacity is our biggest concern. How to choose a laptop hard drive in terms of capacity?

Hard drive provides users with a large amount of storage. And the price is acceptable. So there are still many users choosing hard disk as their laptop hard drive. Here is some information about laptop HDD/SSD sizes.

Laptop HDD/SSD Sizes

Laptop HDD Sizes

For home users, laptop hard drive size ranges from 250 to 500GBs is fine. And most laptop users are using 500 GB hard drive, which is more than enough for the standard laptop system. I have an old laptop with 500 GB hard drive pre-install. Now it is still working and the hard drive space is sufficient.

For users who want to store a lot of movies or other files on this disk, they even want to upgrade to1TB hard drive, which is possible and feasible with a piece of disk cloning software.

Laptop SSD Sizes

SSDs don't come in such large capacities as traditional hard drives. The smallest common SSD size is said to be 128GB, which is about 25 percent of the capacity of the 500GB hard drives you find on many inexpensive laptops. The most common SSD size is 256GB. Solid-state drives rarely have more than 256GB, and those aren't cheap.

Which one is best? Well, it depends on what you’re going to do with your laptop. So, if you don’t play games very often and just use the laptop to handle some official businesses and listen to music, 256GB of SSD storage should be sufficient.

If you're working with a flexible budget, 512GB of SSD storage could be your best choice. And no matter what size is a laptop hard drive, you’d better use a partition manager to manage your hard drive space reasonably and flexibly.
