When you are going to buy an SSD for your computer, form factor is one of the most important factors you need to consider. This article from Partition Magic provides in-depth insights into the SSD form factor. It also explains how to use MiniTool Partition Wizard to securely transfer data to a new SSD or manage your hard drive effectively.

If you are planning to upgrade the hard drive for your computer, you can choose between an HDD (hard disk drive) or an SSD (solid state drive). Although SSDs were once more expensive than HDDs, the price of SSDs has dropped significantly in the past few years.

More importantly, the read and write speed of SSDs is much higher than that of HDDs. SSDs may only take 10 seconds to boot up Windows.

If you are planning to upgrade your computer to an SSD, you must make sure that the SSD type is suitable for your device. How much do you know about the SSD form factors on the market? If you know nothing about the different types of SSDs, don’t worry. You can continue reading this article to get some useful information.

The Introduction of SSD

SSD is an alternative to HDD, also known as a semiconductor storage device, solid-state device, or solid-state disk. SSD uses integrated circuit components (usually flash memory) to store data persistently. Compared with HDD, SSD lacks physical rotating disks and movable read and write heads, so it is more resistant to physical shock and operates silently.

When choosing a solid-state drive (SSD) for your computer, you may pay great attention to aspects such as capacity, performance, lifespan, and price. In fact, you also need to consider whether the SSD sizes are compatible with your device.

Common SSD Form Factors

In the computer industry, the term “form factor” is often used to describe the physical specifications (especially the shape and size) of computer components such as drives, motherboards, power supplies, etc.

When it comes to hard drive size, the first thing that comes to your mind may be the physical size of the SSD. But in fact, the specifications of the SSD are also determined by the connector interface. SSDs with different connectors may have the same size, and SSDs of different sizes may also have the same connector interface.

Of course, there are now SSDs that are directly soldered to the motherboard, and their form factors are only defined by physical size because they do not have any interface.

To help you choose the right SSD size, I will introduce some SSD types classified by size. Let’s take a look at them one by one.

5 Common SSD Form Factors

  • 2.5-inch SATA
  • M.2 SSD
  • mSATA SSD
  • U.2 SSD
  • Add-in card (AIC)

2.5-inch SATA

2.5-inch SSD

A 2.5-inch SSD is a solid-state drive that uses a SATA interface. It is called “2.5-inch” because it is approximately 100mm x 70mm in size and is generally 7mm or 9.5mm thick.

It is the most common type of SSD and is suitable for most laptops or desktop computers. It is similar in shape to a traditional hard disk drive (HDD) and connects via a SATA cable. It is designed to work in the drive bays of most PCs and provides an easy way to upgrade older systems and increase storage performance.

M.2 SSD

M.2 SSD

M.2 SSD is a new type of solid-state drive, which refers to an SSD with an M.2 interface. It is much smaller than ordinary SSDs, about the size of a stick of gum. It can be installed directly on the motherboard through the M.2 slot, without cables and drive bays.

Most M.2 SSDs are 22 mm wide and 80 mm long, marked as M.2 Type 2280.

Common lengths include:

  • 30 mm (2230)
  • 42 mm (2242)
  • 60 mm (2260)
  • 80 mm (2280)
  • 110 mm (22110)

The M.2 interface is divided into two types: B-key and M-key. B-Key is gradually being replaced by B+M Key. B+M Key SSD can be inserted into B-Key and M-Key slots, while M-Key SSD can only be inserted into M-Key slots.

mSATA SSD

mSATA SSD

mSATA stands for mini-SATA and uses the mSATA interface, which is a scaled-down version of the SATA protocol. This type of SSD is compact in design and is only one-eighth the size of a 2.5-inch SSD.

M.2 drives support SATA and PCIe interface options, while mSATA only supports SATA. This form factor is designed for small systems with limited space.

mSATA SSDs are often used in ultra-thin and mini devices with limited space, or as a secondary storage drive for desktop computers to improve computer performance.

U.2 SSD

U.2 SSD

U.2 is another form factor standard to specify the shape, dimensions, and layouts of a physical device. U.2 SSDs are commonly associated with 2.5-inch SSDs, as they look like 2.5-inch SATA SSDs. But actually, U.2 SSDs are thicker than 2.5-inch SSDs.

By contrast, SSDs with the U.2 form factor are commonly more expensive and have higher capacity than M.2 drives.

Add-in card (AIC)

Add-in card

An Add-In Card (AIC) is an expansion device installed through a PCIe slot on a motherboard. It is shaped like a graphics card or sound card and is used to increase the functionality or performance of a computer.

It is a dedicated storage device designed to be installed in a computer’s PCIe slot. Add-In Card SSDs offer superior performance and are suitable for demanding applications such as gaming, data analysis, and content creation. They are usually found on desktop computers.

Clone Data Before Replacing Your Disk with a New SSD

After you have selected an SSD with sufficient capacity, you may want to use it to replace your original hard drive. Before doing so, it is recommended that you migrate your data to the new SSD so that you can boot from the new hard drive without reinstalling the operating system.

To do this, you can use MiniTool Partition Wizard, a powerful disk manager that allows you to easily recover data from hard drive, format USB to FAT32, and convert MBR to GPT.

To migrate data to a new SSD using this utility, you can follow these steps:

Note:
The new SSD should have enough capacity to store all the data from your laptop’s system drive.

Step 1: Attach the new SSD to your laptop or install it internally before starting the system migration.

Step 2: Open MiniTool Partition Wizard.

Step 3: Select the Migrate OS to SSD/HD Wizard option from the left panel of the software interface.

Step 5: Choose the SSD as the target disk and then click the Next button.

Step 6: Choose a copy option and then click the Next button.

  • Fit partitions to entire disk: The partitions on the source disk will be extended by an equal proportion to fill the entire new SSD.
  • Copy partitions without resizing: All the partitions on the source disk are copied into the new SSD without changes in size or location.
  • Align partitions to 1 MB: The Align partitions to 1 MB option will apply 4K alignment on the SSD.
  • Use GUID partition table for the target disk: The Use GUID partition table for the target disk option will apply GPT on the SSD, but it only appears when the source disk is an MBR disk.
  • Change Selected Partition: You can resize or move the partition according to your needs.
