Upgrading the laptop or computer HDD into an SSD is very convenient because almost everyone can do it at home. They are also very affordable depending on what level of performance that you aim for such as with ADATA SU650 Vs Samsung EVO 860. These drives are very popular not only for the competitive price point but also for their overall performance. If your computer needs an upgrade too, let’s see which of the two that will be the better option here.

In this comparison, we are going to talk about:

  • How HDD and SSD Work
  • What are ADATA SU650 and Samsung EVO 860
  • How are the Design of ADATA SU650 and Samsung EVO 860
  • How are the Benchmark of ADATA SU650 and Samsung EVO 860
  • How are the Performance of ADATA SU650 and Samsung EVO 860
  • ADATA SU650 Vs Samsung EVO 860


None of us want to work with a slow computer because it is just frustrating. Our device may have been around for quite some time so it is understandable or they no longer can keep up with the type of task you are going to use them for. One of the easiest ways to improve the performance without having to buy another new device is to change the HDD into an SSD. This small upgrade can be very noticeable but you don’t have to pay as much because SSDs are fairly affordable.

SSDs are very common and widely available today so we are sure you can find them easily whether it is through nearby computer shops or through online retailers. They are very different from traditional HDD but carry the same functionalities. HDD itself has been around for decades and is working with one or more magnetically sensitive platters with an actuator arm. It has a write or read head on for each of the platters while there is a motor to spin the platters as well as moving the arms.

To make it work there is a need for I/O controller and firmware to tell the hardware about what to do and communicate with the rest of the system. It is using mechanical parts to read and write data so they will need time to physically find and retrieve it compared to electronically doing the process. However, nowadays the benefit of HDD is because they are cheaper and are available in larger size which makes it ideal for some people or purposes.

SSD on the other hand is using flash memory to give you better performance and durability. By removing the moving parts, they are durable and run cooler while using less energy. You can see them as a large USB drive because they use the same technology or NAND which is a type of flash memory. The basic options there are floating gate transistors to record a charge or lack of charge to store the data. These gates are organized in a grid pattern then into a block.

Block size will vary but each row making up the grid is known as page. As for the controller, it performs several functions including keeping track of where the data is located. In operation, reading and writing data require all the data in a block to be refreshed when updating so the data will be copied to different blocks, erased, and then rewritten with the change. While in general SSDs are more expensive, they are also superior in performance especially if you games, working with heavy programs, and watching lots of videos.

About ADATA SU650 and Samsung EVO 860

We can perform this upgrade at home with the proper tool but do consider the upgradeability of your device first because not all are using the same parts. It is also helpful to look into the manual or tutorial from those who have an experience just to minimize errors, especially if this is your first time trying to perform such an upgrade. When it comes to SSDs, it is best to get one that matches your budget and performance level.

Not everyone will need the fastest SSDs out there because they will certainly be expensive and there are actually lots of good options on the lower range as well such as Crucial BX500 Vs Kingston A400. If you can spend more, the Samsung EVO line is an impressive option but those who want to keep the budget low, ADATA have some of the most interesting options available to consider. In general SSDs will perform faster than HDD so you can get the advantage even with the entry-level models.

What to note is that they won’t be as reliable as those in the upper range such as how ADATA SU650 and Samsung EVO 860 are compared to each other. You will find Samsung at noticeably higher prices depending on which series they belong to and for this 860, it is currently among the most popular options in this category. It is still pretty affordable but you can find many others at lower cost such as the Crucial BX500 which performs very similarly to each other.

In comparison, the SU650 is even more affordable but performance wise is not up to the EVO 860 yet because the latter is not only fast but also more reliable in the overall performance. However, it is not a bad option at all, moreover when you notice the price point and we do think this can be a great alternative for the lower cost, when you don’t really need that above average experience.

ADATA SU650 and Samsung EVO 860 Design

Before getting into what the ADATA SU650 and Samsung EVO 860 can offer, let’s see the unit first and just like most SSDs, there is nothing special here. The housing is mainly made of plastic so they may not look as sophisticated or as durable as some more expensive options like the EVO 870 but there should not be an issue since we will be mounting it inside the device. These are standard 2.5-inch SATA drives and should fit laptops and PCs as long as the board has the proper connector.

As for the size we can find them in almost any typical capacity from 60GB up to 960GB for the SU650 and from 250GB to 4TB for the EVO 860 so we can choose any sizes that match best with the application and purpose. They are also offering limited warranty for the drive at 3 years by ADATA and 5 years by Samsung.

ADATA SU650 and Samsung EVO 860 Benchmark

Moving to the most important part, let’s see what the ADATA SU650 and Samsung EVO 860 can offer starting from the performance. Both drives are overall better than HDD but the latter is noticeably faster too. The EVO is about 18% faster in sequential read compared to SU650 while the writing speed is even more noticeable at almost 30% faster. The difference in ability to quickly retrieve small pieces of data from random location or known as 4K random is also 50% faster which should be helpful when you start the device.

For the 4K write it is 38% faster in comparison so the performance will be noticeable when you are running applications from the disk or copying them. For sustained writing the EVO 860 comes 55% faster too which means it is more reliable when writing large files. The overall score easily mentions Samsung to be the higher performing drive but it is not surprising because this is a fairly new release and also more expensive than the SU650.

ADATA SU650 and Samsung EVO 860 Performance 

Next for the real world application, the ADATA SU650 and Samsung EVO 860 are not without weakness outside the benchmark because both drives are suffering from inconsistency which means the performance level is not always sustainable leading to varying experience and varying performance for different people or applications. However, overall the EVO 860 is still the more promising option when it comes to performance only because it scores higher in various aspects and making it one of the very few on the top list.

In comparison, even on some of the lowest scores of EVO 860, the speed is still noticeably faster than SU650 so we can clearly see the difference in experience based on the price point and average score. Surprisingly, the SU650 is almost identical when it comes to reading files so if you have many multimedia files like music or photos and videos, the two will work good for typical computer applications including entertainment.


Both ADATA SU650 and Samsung EVO 860 are good options but they are far from being the same. As it has been mentioned above, the SSD needs to be paired with the application or how you need it to be. In comparison EVO 860 is not only going to be faster but also more consistent in application or across different usage in real world conditions despite it not being the best as well. EVO 860 is still one of the most promising in its price range compared to the value we spend on getting SU650.

The SU650 is not a bad option if you are moving from a HDD because it will be faster as well but the value for its performance compared to how many other similar SSD such as BX500 from Crucial is making it not as interesting to opt for. Yet, for those who only use the computer for browsing and typing or enjoying multimedia content, any of the two will be a good choice.
