How to Choose an Internal SSD – Buying Guide

The right internal SSD can drastically improve your computer’s performance. Before you go shop, here are some tips on how to find the right internal SSD for you.

Understand the Differences Between SSDs and HDDs

Understand the Differences Between SSDs and HDDs

SSDs, or solid-state drives, are storage devices for computers. External SSDs are portable but more limited in speed. Internal SSDs are installed on a PC’s motherboard and are not portable, but are much faster. For the best performance, heavy programs and games are usually installed on internal SSDs.


When it comes to internal SSDs or HDDs (hard disk drives), most computers nowadays will usually come with internal SSDs, except the cheapest models. The reason for this is because SSDs are always much faster than HDDs as the primary boot drive.


This can affect the speed of booting your computer, launching apps and programs, and transferring files.

Understand the Differences Between SSDs and HDDs

Even the slowest SSD is three times as fast as an average HDD. Although SSDs will always excel in speed, HDDs do offer a lot more storage space at nearly half the price, or even less. However, HDDs are noisier and take up more physical space than SSDs. SSDs are also more physically durable than HDDs.


SSDs are best for most people who need functionality and reliability. HDDs are only recommended if you need lots of storage space for a cheaper price, such as video collectors. Some computers may also have multiple slots for both SSDs and HDDs.

Determine Which SSDs are Compatible With Your Device

Determine Which SSDs are Compatible With Your Device

You will have to ask your manufacturer or open up your computer to make sure your device’s internal SSD is upgradeable and find out which internal SSD sizes and form factors are compatible. If you want to open up a laptop, make sure that it will not void your warranty if it’s still active.


If you’re upgrading a laptop, you will likely only have space to swap out the existing internal SSD, unless there is another slot. If you’re upgrading a desktop, however, you might be able to add multiple internal SSDs with your original one. 

Determine Which SSDs are Compatible With Your Device

Form factor refers to the physical size and interface of the internal SSD. Internal SSDs nowadays often come in form factors of 2.5-inch drives, which are rectangular, or M.2 drives which are shaped like chewing gum sticks.

Choose an NVMe Interface for the Fastest Performance

Choose an NVMe Interface for the Fastest Performance

For the fastest speeds, look for form factors that are NVMe, or nonvolatile memory express. Other SSDs may be SATA (serial advanced technology attachment), which is much slower but much cheaper. A typical NVMe SSD is over five times as fast as a SATA. You should only consider a SATA SSD if you have an older computer that is incompatible with newer SSDs.


Your computer will have PCIe, or peripheral component interconnect express, slots to add hardware like your internal SSD. Currently, PCIe has six generations. The more recent the generation, the faster the performance of your NVMe SSD. Most PCs nowadays are generations 3 and 4.


If you get an internal SSD that is higher than your PC’s generation, it will be the maximum speed of your PC’s generation. It will work, but you won't get the full benefits from it.

Consider a Heatsink if Your Computer Often Overheats

Consider a Heatsink if Your Computer Often Overheats

Some internal SSDs may offer additional heatsinks, which are cooling pads that encompass your internal SSD. Many thin laptops may not fit heatsinks.


However, if you have a thicker laptop or a desktop, a heatsink can help reduce overheating while using intense programs. You should measure your space before purchasing.

Need More Digital Storage Space?

Need More Digital Storage Space?

Besides upgrading your internal SSD, there are many other devices that can give you more digital storage space. Check out our other articles for more ideas!

Summary

Upgrading your internal SSD can be a life-changing experience. You'll wonder how you ever managed to use such a slow computer before! They can also increase the lifespan of computers as well. We hope we could help you find the right internal SSD!
