It is obvious now SSD (Solid State Drive) would be the preference of choice compared to HDD (Hard Disk Drive). As the SSD price is more affordable now, the advantage of SSD on transfer speed, reliability and form factor has far surpassed the price difference over HDD. But choosing the right SSD for laptops would confusing for most of us.

What is an SSD?

SSD stands for solid-state drive is a new generation of storage device using flash memory to store data. It is mainly used in new notebooks and computers.  SSD is replacing the traditional mechanical HDD due to its much faster access time, transfer rate and low power.

Types of SSD for laptops

There are a few types of interface and form factor available for SSD but to make it simple you can just look into the more popular 2 in the market. If you are upgrading to SSD storage, it is very important to make sure your motherboard support the right interface in form factor.

Some of the most common SSD types are:

  • 2.5” SATA

This is the most common type of SSD that directly replace traditional the 2.5” HDD.  The SSD 2.5” SATA has the same form factor and interface as the 2.5” HDD. If your computer or notebook has a spare SATA connector, it can be connected directly.

In term of price, this type of SSD offers the best value for money with the speed more than enough for most home and office applications, browsing and standard games.

Recently, Samsung introduced an entry level of 2.5” SATA SSD 870 EVO to replace Samsung SSD 860 EVO.

  • M.2 NVMe

M.2 SSD has the form factor like a DRAM stick. The more common form factor is 2280 which represents 22mm width and 80mm length, although it can vary in some notebook. M.2 NVME SSD is a PCIe based with much bigger hence faster bandwidth compared to the SATA interface.

Although it is a bit premium in the pricing, M.2 NVMe SSD would give a significant faster speed when you are using for high-end games, video editing, large data processing and transfer.

Some high end NVMe SSD for gamers offers a good deal too, you can consider Hewlett Packard HP SSD EX950.

  • M.2 SATA

This is M.2 form factor but with SATA interface, performance and price. There are less common notebook using M.2 SATA now. 

So, before you choose an SSD for your laptop, you need to check and make sure which form factor and interface your notebook or computer supports. Choosing the right SSD for laptop would be easier after you understand the basic type of SSD.

Size of SSD for laptops

The next thing you need to decide is how big capacity you need. It really depends on your need and the data you need to store on your SSD.  Although SSD is available in 128GB and below, I would suggest getting at least 240GB and above.  Because there is not much price difference between 120GB and 240GB.  But if you are looking for mid to long-term usage, 500GB SSD would be a sweet spot.

SSD capacity is available in 250GB, 500GB, 1TB, 2TB, 4TB and 8TB now.


Choosing SSD for laptops can be a complicated thing but this information should give you a better understanding of SSD types. Just remember to make sure you check the right type of SSD your laptop support, the capacity and lastly your budget.
