Top 5 Comparing Performances: Internal Vs External SSD

Which is Faster? Internal or External SSD?

internal vs external SSD performance

It is commonly accepted that an SSD outperforms a hard drive. Were you aware that SSDs can be categorized into two types? In this blog post, we’ll compare the performances of internal vs external SSDs to help you decide which one is right for you. Stay tuned!

What is an SSD?

A storage device that utilizes flash memory to save data is called a Solid State Drive or SSD. Due to their numerous benefits over conventional hard drives, SSDs are gaining popularity. SSDs, unlike hard drives, are faster and consume less power, thereby increasing the longevity of the battery.

Internal SSD: Overview

An internal SSD is a storage device that connects to a computer’s motherboard using the SATA interface. Unlike a traditional hard drive, an SSD has no moving parts and stores data on interconnected flash memory chips.

It makes it more durable and much faster, potentially dramatically improving your computer’s overall performance.

External SSD: Overview

An external SSD is a storage device that connects to a computer via a USB port. External SSDs often store large files such as photos and videos. They are also frequently used to back up data from a computer’s internal hard drive.

External SSDs can be connected to a computer using either a USB 2.0 or USB 3.0 connection. The data transfer rate increases as the connection speed increases.

Pros & Cons of Internal SSDs


  • Faster speeds than traditional hard drives.
  • Low power consumption, enabling longer battery life and cooler running temperatures.
  • Increased reliability and durability due to having no moving parts.
  • Small form factor, making them ideal for mobile devices and small computer cases.
  • Significant cost savings over external SSDs or other storage solutions that require additional hardware.


  • Limited storage capacity compared to external SSDs or hard drives.
  • Higher price per gigabyte than external SSDs or hard drives of similar sizes/capacities.
  • Not compatible with all devices/computer systems due to different connection types (i.e., SATA vs NVMe).
  • More complex installation process than simply plugging in an external drive or swapping out a hard drive in a laptop/desktop system.
  • Limited upgradability, as the internal drive, must be replaced completely if you need it.

Pros & Cons of External SSDs


  • Increased data transfer speed compared to traditional hard drives.
  • Low power consumption and long battery life.
  • More durable than traditional hard drives due to lack of moving parts.
  • The smaller form factor makes them easy to transport and store.
  • Most external SSDs are compatible with Mac and Windows operating systems.


  • Expensive compared to traditional hard drives with similar storage capacity.
  • Not as much storage capacity is available as a traditional hard drive with the same price point.
  • A limited number of connection options are available on some models, such as USB 2 vs USB 3 or lack of Thunderbolt support.
  • Can be affected by external conditions such as extreme temperatures or shock from impact or dropping the device, which can damage the internal components of the drive and render it unusable until serviced by a professional technician.
  • Incompatibility with some older.

Other Considerations

best SSD for the better performance

1. Internal SSDs

Internal SSDs are drives that are installed inside a computer. They typically come in the 2.5-inch form factor, but there are also some M.2 and mSATA drives available.

Internal SSDs offer a number of advantages over traditional hard drives, including faster data transfer speeds, lower power consumption, and increased durability.

2. External SSDs

External SSDs are drives that are designed to be used with a computer via an external connection, such as USB 3.0 or Thunderbolt.

External SSDs offer the same advantages as internal SSDs, but they also offer the convenience of being able to be used with multiple computers without having to open up the case and install the drive inside.

3. Cost

The cost of internal and external SSDs can vary depending on the capacity and brand, but in general, internal SSDs tend to be cheaper than external SSDs. This is because external SSDs need to include housing and interface circuitry, which adds to the overall cost.

4. Capacity

Internal and external SSDs are available in a variety of capacities, ranging from 128GB to 4TB. The capacity you need will depend on your needs and budget.

If you just need to store your operating system and basic programs, a 128GB drive should be sufficient. However, if you plan on storing large files or have a large media collection, you may want to consider a drive with a higher capacity.

5. Performance

Internal and external SSDs offer significantly faster data transfer speeds than traditional hard drives. This is because they use newer technologies, such as NAND flash memory and PCI Express interfaces.

The exact speed will vary depending on the specific drive, but in general, you can expect an internal SSD to be around 2-3 times faster than an external HDD, while an external SSD will be around 4-5 times faster than an HDD.

6 . Reliability

Internal and external SSDs are also more reliable than HDDs due to their lack of moving parts. This means that they are less likely to fail due to physical shock or vibration.

Difference between internal and external SSD

internal vs external SSD
  1. Internal SSDs are installed inside your computer, while external SSDs are portable and can be connected to your computer via USB.
  2. Internal SSDs are typically faster than external SSDs, as they don’t have to contend with the slower USB interface.
  3. External SSDs are more convenient as they can be easily disconnected and taken with you, while internal SSDs are more difficult to remove and transport.
  4. Internal SSDs tend to be more expensive than external SSDs.
  5. External SSDs are available in a variety of sizes, while internal SSDs are typically limited to 2.5″ or 3.5″ form factors.
  6. External SSDs usually come with a protective case or enclosure, while internal SSDs do not.

Is it better to have an internal SSD or an external SSD?

An internal SSD is typically faster and more reliable than an external SSD, but it is also more expensive. An external SSD is less expensive and still offers good speed and reliability, but it is not as fast or reliable as an internal SSD.

Ultimately, the best option for you will depend on your budget and your needs. If you need the fastest and most reliable storage possible, then an internal SSD is the way to go.

But if you’re on a budget and don’t mind sacrificing a bit of speed and reliability, then an external SSD is a good option.

Is it worth getting an external SSD?

Internal hard drives can fill up quickly, and external hard drives can be slow and cumbersome. One solution is to use an external solid-state drive (SSD). SSDs are much faster than traditional hard drives, and they are now available in a wide range of sizes and price points. 

Why would you choose an external SSD instead of an internal drive?

When it comes to external storage solutions, SSDs have a lot to offer. They are lighter and more portable than traditional hard drives, and they are also more resistant to shock and vibration.

In addition, SSDs generally have faster read and write speeds than their mechanical counterparts. However, there are a few things to keep in mind when choosing an external SSD.

  • First, make sure that the drive is compatible with your computer.
  • Second, consider the amount of storage space you need.
  • And finally, be sure to factor in the price.

Is there any downside to an external SSD?

One of the main concerns is durability; because SSDs have no moving parts, they are more resistant to physical damage than hard drives.

However, they can still be damaged by extreme heat or cold, and they are more likely to be damaged by water than hard drives. In addition, SSDs can be more expensive than hard drives, and they tend to have lower storage capacities.

As a result, it is important to weigh the pros and cons of an external SSD before making a purchase.
