A desktop and a laptop SSD will offer different levels of performances due to the differences in their features and abilities. If you are a first timer, it will not be easy for you to make a choice between these two types of SSDs.
This article comes up with some notable differences between the two SSDs in terms of their design and other technicalities.
- The laptop SSDs typically come in a 2.5 inch form factor but the desktop SSDs are larger than that having a 3.5 inch form factor.
- The laptop SSDs are usually 7 mm thick but the desktop SSDs are usually 15 mm thick.
- A laptop SSD can be used in a desktop computer but such a switch cannot be made in a laptop computer.
The 6 Differences Between Desktop and Laptop SSD
One of the major differences between a laptop SSD and a desktop SSD is their thickness.
The 2.5-inch desktop SSD or U2 is twice as thick in comparison to a conventional laptop drive. In fact, the U2 will usually be 15 mm thick.
On the other hand, the laptop SSD will usually be 7 mm thick.
However, the bay in some of the laptops may support a 9.5 mm thick drive but certainly not a 15 mm thick drive like in a desktop computer.
2. Form factor
The laptop drives typically use a 2.5″ form factor. On the other hand, the desktops use a 3.5″ form factor.
This means that you can use a larger drive in a desktop with larger capacity since weight and space are no constraint in a desktop computer as they are in a laptop computer.
With reference to the form factors of the SSDs, you can use a laptop SSD in a desktop computer because the bay will support the 2.5” SSD that a laptop typically comes with.
On the other hand, a desktop SSD will not fit in a laptop if it is 3.5” in size.
Though not related directly to the SSDs, the enclosure of the laptop to fit an SSD may be smaller than the enclosure of the desktop.
This might cause some issues when you want to install a desktop SSD in a laptop SSD being larger in size.
5. SATA Connections
However, the desktop computers can support SSDs of higher form factors with the same type of SATA connections.
For example, while installing a 2.5” drive in a 3.5” drive bay you will require a 2.5″ → 3.5″ drive/SSD mount.
On the other hand, there is no such need in the case of a laptop SSD because it normally supports only one type of form factor.
Which One is Better to Use?
Ideally, it depends on whether you have a desktop or a laptop computer.
As you can see from the differences above, a laptop computer will allow using only an SSD with a small form factor.
So, considering the physical dimensions, you really do not have much of a choice left.
Almost all SSDs today come in a 2.5″ form factor which can be used both in a laptop or a desktop computer.
However, mind the word ‘almost’ in the sentence because you do get some SSDs in a 3.5” form factor as well.
Therefore, the internal differences really have nothing to do in deciding which among the laptop SSD or a desktop SSD is better to use.
It is simply about the capacity and the manufacturer that you should focus on.
One most important thing to focus on is the number of bits that can be stored in every cell.
The single-bit cells, also known as Single Level Cells or SLC are fastest, long-lasting and robust but are expensive.
The 2-bit cells and 3-bit cells also known as Multi-Level Cells or MLC and Triple-Level Cells or TLC respectively are good though the quad-bit cell or the QLC is the cheapest choice.
Now, if you want to use a laptop SSD on a desktop computer or vice versa, then you will need to consider a few specific factors in order to determine the compatibility with your computer system.
In most cases, installing a desktop SSD in a laptop may not be allowed but this is not absolutely impossible.
Everything depends on the size of the drive itself. If it is size of the drive fits into the bay, you can go ahead and make the switch after considering these following factors:
- The operating system support
- The right drivers are installed and
- Its usage.
Therefore, as you can see, the main consideration is whether or not the drive will fit in your device.
Finally, no matter whichever SSD you use, make sure that you use one that is manufactured by a reliable company and is of good quality. Researching and reading reviews are crucial.
As it is pointed out by this article, there is really not much difference between a laptop SSD and a desktop SSD.
Apart from the form factor, there is nothing significantly different in the two that will affect the tasks they perform.
