Samsung QVO Vs EVO — Which one is Better & Why?

Samsung QVO Vs EVO

Computer storage devices have come a long way since they were first developed. They have become more compact than ever before. The very first hard disk drive, launched by IBM in 1956, weighed 2000 pounds. Moreover, it had a capacity of only 5MB. Considering that, we have come a very long way indeed. Nowadays, storage devices can store up to 14TB, depending on the type — whether it’s a hard disk drive or solid-state drive. 

SSDs are preferred by some users for their reliability and speed. The ones made by Samsung have been quite popular. Recently, they have launched the 870 EVO SSD. In light of that, there is an ongoing discussion about which one is the better one among QVO and EVO. Here, you’ll find some useful information on Samsung QVO Vs EVO that’ll help you decide for yourself. 

How do they work?

As opposed to hard disks, they don’t feature spinning disks for storing their data. Instead of that, they come with semiconductor chips. In case you’re wondering, what that means, it’s simple to understand with an example. 

Suppose you’re using an SSD with a computer and the power goes out. As a result, your computer would lose power and the data in your RAM will be lost temporarily until you power it back on. However, that’s not the case with your SSD. In other words, the data that you store in them isn’t volatile. You can access them by just connecting them to another device. Moreover, they also require comparably less power to function than hard drives. 

Which one has a bigger storage capacity?

While choosing a storage device, Samsung QVO Vs EVO, the capacity would probably be one of your topmost priorities. After all, that’s the main purpose you need them for — storing as much as possible. The two options here come with a range of storage options. The 870 QVO starts at 1 TB and can have a maximum of 8TB. That’s comparably bigger than the EVO, which can go up to 4TB. 

However, the storage requirements vary with each user. What if you don’t require a capacity as high as 1TB? In such cases, you might find the EVO comparably more favorable as it comes with a minimum capacity of 250GB. 

Which one among the two has a better reading speed?

When you open a file saved on the storage from a device, it takes a certain time to open. This is what’s meant by the reading speed of a storage device. In case you’re wondering, it is measured based on the number of megabytes recorded each second. This would be useful for you in comparing various devices. 

The 860 EVA has a reading speed of 550 Mbps. In comparison, the 870 QVO has a slightly better performance at 560 Mbps. That means it’ll open a file quickly only in a few seconds. It can be said that their difference, Samsung QVO Vs EVO, isn’t significant enough in this matter. 

How do their writing speeds compare?

Suppose you’re saving a file from an SSD to your computer, the amount of data that it transfers to your device would be its writing speed. You can compare two storage devices in this matter by transferring a fixed file size on your computer. 

In this matter as well, you’d find the 870 QVO to be far better at 530 Mbps. The other one has a writing speed of 520 Mbps, which is average. So, there’s not a big enough difference in both the options. The only time it would matter is when you’re dealing with large files, and the same goes for reading speed. 

Which one should you choose for better writing endurance?

In case you were not aware, there is only a limited amount that you can save in your storage device through its lifetime. Suppose you crossed that limited amount just today, so from that point onwards, the device will become unreliable for use. Thus, it would be best that you buy another one. This parameter is measured in TeraBytes Written. 

The QVO is reliable for up to 2880 TBW. On top of that, it is also assured by the manufacturers to last at least 3 years. In the EVO, on the other hand, you get a reliability of 2,400 TBW.  However, the manufacturers have assured a lifetime of 5 years. In case it stops working before that, you can get a replacement under certain circumstances. 

In this case, you basically have to decide whether you want more warranty or more lifetime. Both would be fair, and none of them can be called better than the other. It’s all a matter of preference, Samsung QVO Vs EVO.

How do their prices compare?

First, you need to understand how the pricing works in the case of an SSD. For that, you have to go a little deeper into the matter. As you see, the QVO series uses quadruple-layer cell chips. That means you’ll have three times the memory density as compared to a single-layer cell. 

On the other hand, the EVO comes with a triple-layer cell. Now, as you can guess, they have three layers of information on the chip. The noteworthy aspect is that the price will decrease with the increase in layers. However, it is not as simple as it looks like. That’s because having more layers of memory means the chip has to work more. 

As a result, they might last shorter. So, it’s up to you to decide which one you’ll prefer, Samsung QVO Vs EVO. However, there’s no doubt that the QVO is better for your budget. 

Which one is better for gaming?

As you’ve seen, the QVO has more memory density. As a result, it’ll be slower as compared to the EVO. So, it won’t be wrong to say that the latter would provide you with a better performance in gaming. 


When you have to choose between the QVO and EVO from Samsung, there are a lot of things you might want to consider. All the relevant points have been discussed here. Hopefully, it has been helpful to you in making the right decision, Samsung QVO Vs EVO, after all, the requirements differ with each user. 

Frequently Asked Questions: 

Is QVO faster than Evo?

The Samsung 860 QVO isn’t as speedy or as energy-efficient as the Samsung 860 EVO, but it doesn’t have to be. The 860 QVO is still capable of serving as a general-purpose consumer storage device. The QVO is slower than the 860 EVO, but it’s not the slowest SATA SSD we’ve seen. 

Is QVO good for gaming?

This drive is totally fine for general use and game storage, and it will provide significant improvement over standard mechanical hard drives.

Is Samsung Pro better than EVO?

The PRO outperforms the EVO in mixed workloadsHowever, the differences aren’t significant; in many cases, there isn’t much of a difference between the two. Based on storage capacity, there are variances across the full range of Samsung drives.
