Samsung, a well-known player in consumer electronics, also builds some highly reliable storage devices, including SSDs. In fact, Samsung is one of the best-selling SSD brands on Amazon owing to the amazing speed, reliability, and ease of management that its SSD drives offer. The single most liked feature of Samsung SSDs is their data migration software, which is consistently rated amongst the best in the industry.

But, with the market full of so many different models of Samsung branded SSDs, it can be hard to tell which Samsung SSD to pick. And, Samsung’s naming convention doesn’t help too. It’s quite difficult to understand things like which Samsung SSD model wins in a battle of Samsung QVO versus Samsung EVO, for instance.

That’s precisely where this article will be helpful for you. I’ve done full research regarding this, and come up with this full-fledged information about Samsung Evo vs QVO SSD. In this guide, we’ll discover all the differences between the Samsung QVO and Samsung EVO SSDs.

So, let’s get started.


Samsung SSD Evo & QVO – General Overview

Until recently, Samsung only had two types of SSDs – the Samsung Pro and the Samsung EVO. But things changed in 2020 when the company came up with its third line of SSDs, dubbed the Samsung QVO. Today, all three are available in the market. While the Pro SSDs are the pricey ones, the other two types (EVO & QVO) are more affordable.

The main difference between the EVO and QVO line of SSDs comes from the type of flash memory they use. The Samsung EVO SSDs use TLC NAND (3 bits per cell) while the QVO SSDs use QLC NAND (4 bits per cell). But, what does that mean? To state simply, TLC NAND offers a good storage density, but it also tends to have better performance and longevity. QLC NAND, on the other hand, has a shorter lifespan but offers a higher storage density than its TLC counterpart.


Samsung SSD Evo vs QVO – Specs Comparison

Now, let’s do a specs comparison of the Samsung SSD Evo vs QVO to know more about the difference between the two drives.

Read/Write Speeds

The read and write speed of your SSD is the single most important factor that you should consider before buying a drive for yourself. After all, you’re spending all these bucks just to see a significant improvement from your standard hard drive.

As mentioned before, Samsung QVO uses QLC NAND, which is why it’s slower than EVO which uses TLC NAND. While on paper you may see both the 870 EVO and the 870 QVO offering 520MBps write speeds and 550MBps read speeds, it becomes possible only due to Samsung’s Intelligent TurboWrite technology which temporarily accelerates the write speeds at which the SSD can move data. But, this boost is available only up to the maximum data capacity that Intelligent TurboWrite can function for. After that, the QVO SSD will fall behind in terms of speed.

Storage Capacity

While Samsung EVO SSDs are faster than QVO, the QVO ones win in terms of storage capacity. Let’s compare the Samsung 870 EVO and the Samsung 870 QVO, for example.

The 870 EVO is available in 250GB, 500GB, 1TB, 2TB, and 4TB storage sizes. The newer 870 QVO, on the other hand, offers considerably larger capacities ranging from 1TB, up to a whopping 8TB, while also coming with 2TB, and 4TB variants. Therefore, if we’re looking at the possibilities, the Samsung QVO range of SSDs offers higher capacities.

Life Span

The longevity (or life span) of an SSD is measured in TBW (TeraBytes Written) (TBW). It refers to the number of terabytes you can write to the SSD before it reaches the end of its lifespan.

As mentioned before, since Samsung QVO uses QLC NAND, it generally offers a shorter lifespan than its EVO counterparts which use TLC. Now, let’s compare the Samsung 870 EVO and the Samsung 870 QVO once more:

  • 1TB: 600 TBW – EVO; 360 TBW – QVO
  • 2TB: 1,200 TBW – EVO; 720 TBW – QVO
  • 4TB: 2,400 TBW – EVO; 1,440 TBW – QVO

Therefore, you can expect the Samsung EVO to last longer than the Samsung QVO.


Owing to their slower speeds and higher capacities, Samsung QVO drives are better suited for storage rather than constant read and write actions. But, if you want an SSD for constant use on your operating system, the smaller EVO SSDs are more suitable.

So, while the Samsung QVO line excels at read-intensive workloads, it lags behind when it comes to write-intensive tasks.


While both the EVO and the QVO are more reasonably priced (when compared to Samsung’s PRO SSD range), the QVO drives are cheaper than EVO. Again, let’s compare the price of the Samsung 870 EVO vs the Samsung 870 QVO.

Here’s the price of both.

Samsung SSD QVO vs EVO – Which One Is Better?

Both EVO and QVO lines of Samsung SSDs are affordable if we compare them to the premium Samsung PRO SSDs. If you want to get an SSD that’s better in terms of overall performance and longevity, then the Samsung EVO is a great option for you. But, if you want an SSD that’s even more affordable and comes with higher capacity options, then you may go for an SSD in the Samsung QVO range.

Other than that, you may also decide on the better option for you based on what your use case is. For those who want an SSD for your operating system, buying a smaller Samsung EVO, such as the 870 EVO is the better option. However, if all you’re looking for is bulk storage with comparatively faster speeds than typical hard drives, the Samsung QVO drive is what you should choose.
