Top 10 Best SSDs for Laptops (2021)

Edited By Piyush, Reviewed By Gulshan

SSDs, new solid-state drives are used everywhere. They improve the speed of your computer or laptop while allowing you to run things smoothly.

HDDs, hard disk drives, were used to store data earlier, but now SSDs are replacing them. Then SSDs were invented around the 1950s.

But did you know in the 1970 and 1980s they were only used in high-end supercomputers? Only the military and aerospace sectors used them because SSDs were relatively expensive and consumers couldn’t really afford them.

Besides their storage space was of only 2MD-20MB, which was small compared to their 5 digit prices. Then during the early 1990s, a lot of hardware innovations caused the price to decrease and was affordable by the general public.

It wasn’t that famous though. SSDs still had issues with their lifespan and size. Then in the 2000s SSDs became advanced and could be reliable and last for decades.

Wondering where else SSDs are used now? Well, they are used almost everywhere in high-performance technology areas. Here are the areas where people use SSDs.

  • Gaming: Gaming computers need a lot of loads to carry and the current computing technology doesn’t satisfy them. Modern amazing games require a lot of storage, constantly loading and writing files, like textures, maps, characters, etc.
  • Business: Companies have a lot of data to store such as programming environments or even with data analysis. So, they usually depend on SSDs as they need speed in file-transfer and such.
  • Mobility: SSDs contribute to better battery life in laptops and tablets because they have low power requirements. In addition to that, they are also shock-resistant, which means that the risk of losing your data if anything like that happens, is reduced.
  • Servers: In order to serve and satisfy their clients, enterprise servers need SSDs as it gets them faster reads and writes.

Now you might even be a student, you will still need an SSD. There are so many options in so many different prices that will leave you confused. Don’t worry, in this article, everything about SSDs will be given to you, along with specifications, pros and cons and much more.

We Highly recommend you to read the SSD Buying Guide at the end of this article to get in-depth knowledge about the latest [item name] technologies and tips on making an informed decision about which product to buy for your needs 🙂

Buyer's Guide: How to Purchase SSD for Laptop

A good SSD is a key for a fast laptop. A lot of times people buy rather cheap or incompatible SSD for their laptops without researching the product or their machine first. This is a bad strategy as people lose money and time without gaining any substantial value or at times, any value at all.

So before you decide to buy a new monster of an SSD for your laptop, make sure that you are aware of all the little details. So here is a buyer guide to get you started

  • Budget: A lot of times, people forget to take their budget into account and go on a spending spree. Instead of buying a high-end SSD whose extra features are basically useless to your personal use case or an extra cheap one that doesn’t perform as well, buy according to your budget.
  • System Support: Not all SSDs are compatible with your laptop. There are features like the form factor of an SSD that decide if the particular SSD is compatible with your laptop or not. It is a good idea to research the form factor, the connection types and the hardware support of the SSD and your laptop before making the purchase.
  • SATA or NVMe: If your daily job consists of just browsing over the internet and formatting files, then a relatively slower and cheaper SATA drive will work for you. But if your job requires handling of massive data like video editing or gaming, then a faster NVMe drive should be your pick.
  • Capacity: The 128 GB models are extremely cramped and can only fit your operating system with some applications. If booting time isn’t all that you are looking for, you should stay away from these. Buying a 256 GB version or higher is a better option if you want all or most of our data on the SSD. Also, as the size of the SSD increases, so does its speed.
  • Power Consumption: SSDs consume less power than a traditional hard disk. Still, depending on the battery size of your computer, choose an SSD. Be aware, low power consumption also means lower speeds, so you have to strike the balance.
  • Type of memory: Unless you are doing some professional work that requires you to know this, you don’t really need to waste your time researching this.
  • Endurance: Unless put on a server, the general lifespan is 3-5 years.

Frequently Asked Questions

1. Is it worth getting an SSD for a laptop?

The answer to this is simple, YES! SSD gives you huge amounts of space to store your data. And even then your laptop will work really smoothly, the performance is a lot faster compared to the typical HDDs. In addition to that, SSDs require no mechanical parts which are why they need less power to run. So, you will have an advantage in the power consumption area. SSDs are also shock-resistant, which means that even if your laptop drops, all your data will be safe. Although they may be a little expensive they are definitely worth it as all this will give you an amazing experience.

2. How do I know which SSD is compatible with my laptop?

First, you must have a new model of a laptop because chances are, the older models don’t support SSDs. You can confirm by calling the customer service or by doing a little research online. After you have done that, you need to make sure you find the right-sized SSD, because you certainly don’t want to insert an SSD that doesn’t fit into your laptop. Even your model does support an SSD, it may not support that one exactly. You can search for teardowns and information about the SSD slot of your laptop on YouTube or check one of these links:

3. Is 256GB SSD enough for a laptop?

The answer to this is yes and no. If your laptop can install a few drives then yes, 256GB is enough. But if your laptop can install one drive, then well it won’t be enough. Gaming, documents and common programmes like google, take up hundreds of GB space. If you are planning to run simple tasks on your laptop like, watch videos, play music, browse, etc, then it is okay to get a 256GB SSD drive. But if you are editing videos or gaming a lot on a one driving bay, then it won’t be enough.

4. Can I have both SSD and HDD in my laptop?

It really depends on your laptop. If your laptop has an additional slot for an SSD then you can use one. If not, then an external drive is the best option for you. In fact, if your laptop supports it, it is recommended to use an SSD in conjunction with an HDD. The general way of doing it is to install the operating system and certain important applications on the SSD and keep the rest of the data on the HDD. This is done to achieve faster-booting speed and shorter launch time on daily driver applications without cramping the SSD.

5. How long does a SSD last?

The average lifespan of an SSD is usually 10 years but it can be shorter depending on the TBW (TeraBytes Written over time), if the manufacturer says the SSD has 150 TBW that means it can write 150 terabytes of data. After it reaches this point, you will need to change it. Based on other factors like DWPD (Drive writes per day) and the age of SSD, lifespan is determined. In short, it means the SSD will last depending on how much data you run on it. But even then, researchers found out that people replace HDDs 25% more than they are to replace SSDs.
