Overview of Samsung EVO and QVO

To figure out which is better and how to choose the best SSD for you, we will analyze each one thoroughly and compare Samsung QVO vs. EVO. Let's start with the basic information and specification of Samsung EVO and QVO.

What Is Samsung EVO

Samsung EVO SSD line is based on Samsung's latest V-NAND technology, which can help SSD maintain fast and reliable performance with its upgraded performance even under heavy workloads and multitasking. This groundbreaking technology meets the needs of anyone from IT professionals to everyday users. The latest 870 EVO can speed up to 560/530 MB/s for its sequential read/write speeds. While the 860 EVO can deliver up to 550 MB/s and 520 MB/s sequential read/write speeds with the improvement of intelligent TurboWrite technology. In addition, the TurboWrite buffer size has been upgraded from 12GB to 78GB, over six times that size.


  • Very fast record-setting 4K read and write speed for SATA drives.
  • It has a five-year Limited Warranty.
  • It rates high in durability with six-proof protection.


  • This EVO model doesn't have a SATA cable to connect to PC.

What Is Samsung QVO

Samsung QVO was released on June 30th, 2020, as a series of QLC SSD. The second-generation QLC SSD is now the Samsung 870 QVO, which can provide incredible upgrades for everyday PC users of desktop PCs or laptops without sacrificing performance. Most importantly, it allows you to have high-capacity storage and speed comparable to high-end SSDs at nearly half the price of a similarly sized Samsung PRO SSD. Intelligent TurboWrite accelerates write speeds, and the latest Samsung 870 QVO can even reach the maximum SATA interface limit of 560/530 MB/s sequential speed. At the same time, the Samsung QVO will maintain high performance over time with a more significant variable buffer.


  • Relatively low price for improved and competitive performance of SATA-based SSD.
  • Available in 8TB storage capacity.
  • Feature Samsung Magician 6.1 management software that can help you manage your drive.


  • It only has a three-year warranty. 
  • Write performance will slow down after the SLC cache is full.

Samsung QVO vs. EVO: What Are Their Differences

Samsung QVO and EVO are among the most potent SATA SSDs in the market. Although they are developed by the same company and similar in some specifications, there are considerable differences. In this section, we will discuss their differences by comparing the following six aspects:

Comparison Samsung QVO Samsung EVO
🎪Storage Size 1TB, 2TB, 4TB, and 8TB 250GB, 500GB, 1TB, 2TB, and 4TB
⏳Longevity(TBW) 360, 720, 1440, and 2,880 150, 300, 600, 1200, and 2,400
🚀Transfer Speed 80MB/s 300MB/s
📀Memory Type QLC (Quad Level Cell) TLC (Triple Level Cell)
💶Price $109.99~$679.99 $54.99~$379.99
👨‍🔧Warranty 3 Years 5 Years

Now, keep reading to get more details about how Samsung QVO and EVO are different from each other:

Samsung QVO vs. EVO: Storage Size

SSD is used to extend the storage space, making storage size an indispensable factor for determining whether an SSD is good. It's easy to tell from the table above that QVO has a larger storage capacity than EVO. QVO starts at 1 TB and charges lower than EVO for the same capacity, although the latter has various sizes.

Samsung QVO vs. EVO: Memory Type

Both SSD use NAND flash memory, but there are five main types of NAND. The Samsung QVO uses QLC NAND (4 data bits/cell), while the EVO uses TLC NAND (3 data bits/cell). QLC NAND type is slower than TLC, spending more power given to more cells.

Samsung QVO vs. EVO: Performance

Why do people prefer to replace their HDDs with SSDs today? I would say the answer is higher performance. According to the transfer speed test, QVO can reach 80MB/s, while EVO can transfer data at 300MB/s. However, Samsung has developed the Intelligent TurboWrite technology, which allows lower-quality SSD to stimulate the read and write speeds of technically superior SSD. Thanks to Intelligent TurboWrite, the read/write speeds of QVO are ascended to 560 MB/s and a write of 530MB/s, the same as EVO. Yet, Intelligent TurboWrite will slow down the speed or lose its function when the SSD transfers around 42GB to 72GB of data.

Samsung QVO vs. EVO: Lifespan

The SSD's lifespan is measured in terabytes written (TBW), representing how many terabytes of data you can write to the SSD before it breaks down. EVO SSD has more extended longevity than QVO since TLC NAND has higher longevity than QLC NAND.

Too much information? It's time to hear what professional review says about the Samsung QVO vs. EVO:

Review from Coolblue: The Samsung 870 QVO and 870 EVO both have their advantages and ideal usage situation. For everyday use, the 870 QVO is a suitable choice. Your computer or laptop boots faster, and you have the option to choose an SSD with up to 8TB of storage. If you often work with large files or transfer a lot of data, the 870 EVO is the right choice. The faster and more energy-efficient TLC memory combined with the longer lifespan ensures better performance.
EaseUS Editor Review
Let's sort out the pros and cons of these two SSD lines. Regarding EVO, the most prominent advantages are a surprisingly long lifespan, a reassuring 5-year warranty, and blazing-fast transfer speed. However, it's unaffordable and generally has a lower storage size than QVO. For QVO, it's excellent for its significant increase in storage space and relatively economical price. The shorter warranty and lower transfer speed may drag its leg.

Samsung QVO vs. EVO: Which One Should You Use

After going through the basic specification and comparisons of Samsung QVO and EVO, you must have a preliminary understanding of these two SSDs. Here comes the question - which SSD should you use? For your information, we have collected some pertinent comments from the leading review sites. Let's check one of them:

Review from Digital Trends: On paper, it's hard to deny that the Samsung EVO line of SSDs will perform better and may enjoy greater longevity than the Samsung QVO. On the other hand, many users won't notice much difference in day-to-day tasks, and unless you're in a big hurry, you likely won't mind whether it takes 30 seconds or 3 minutes to transfer a big file.

To give further support for you to make the right choice, the EaseUS editor will provide some valuable suggestions for you to refer to:

EaseUS Editor Review

Generally speaking, both EVO and QVO are good choices. I will offer two perspectives to help you consider:

From the SSD performance: if you value the storage space and have an insufficient budget, go for OVO. On the contrary, choose EVO for its extra lifespan, superior performance, and generous warranty time.

Frome users or usage situation: if you are an enthusiast with occupational demands for faster transfer speed and the best processor, turn to EVO. You better take QVO if you need general use for games or day-to-day tasks.


As fantastic SSDs, Samsung QVO and EVO have their strengths and are ideal for different usage situations. If you're trying to find a good option for general use, like playing games, consider buying a Samsung QVO. It can provide various sizes up to 8 TB and faster boot speed. If you have some extra money and often work with large files, you'd better choose Samsung EVO. More rapid transfer speed combined with a longer lifespan can ensure better SSD performance. We hope this guide can enlighten you on deciding between Samsung QVO and EVO.
