WD Blue SSD vs Samsung 870 Evo: Which is better for you?

As the changes in technological devices are increasing day by day, we see that not only the forms of storing the data for us are variant and modern enough but also their mediums. This is true in terms of permanent storage as well.

Data storage is an important aspect when it comes to keeping your important files secure for a longer period of time and when it’s done rapidly, then it obviously gets more audience attention.

Yes! You guessed it right. We are going to discuss SSDs today in this article. These have replaced hard disks and provided a faster means of flash memory storage.

What is an SSD?

SSD stands for solid-state drive and is far better in comparison to the typical hard disk drive that we used to work on. Many computers today are comprised of HDD, but if you are looking for something that is really fast enough as a whole, then SSD is the right pick.

Components of an SSD:

An SSD is a more reliable and efficient form of non-volatile file storing that has no such movable components and totally relies on flash memory chips and the flash controller.

Comparative study of WD Blue SSD vs. Samsung 870 Evo:

Those who are already aware of the SSD concept can skip the upper part and read our article’s main topic, which is the selection between the two SSDs. These are WD blue or the Samsung 870 Evo.

WD Blue SSD vs Samsung 870 Evo: Which is better for you?

As mentioned earlier, the components of an SSD determine the optimal performance delivery for the users and maximize the process of reading and writing on the disk, so we are going to look for all the relevant properties of SSD to be compared in a proper manner.

They both have the same read & write speeds, but the WD Blue is less expensive and performs well. I prefer the WD Blue SSD for Regular use. But For gaming, I Prefer Samsung SSD.

Brand and Model:

The brand helps in getting the user’s trust towards the device and has its own charisma and specifications for the users it is serving to.

The brand for the WD Blue SSD is Western Digital, while for the 870 Evo, it is Samsung as there are both sequential and random data requests done, so the ongoing advancement in the models caters to these requests in a profound way.

The model for the WD Blue is WDS500G2B0A, while you can get the 870 Evo in MZ-77E500B/AM, MZ-77E500B/EU, or MZ-77E500BW.

Capacity and interface:

When you are getting an SSD, you must know the storage capacity it can hold for you. This is useful regarding the type of data or files you would like to keep forever.

If it is going to be all media-related data, then you must get a high-capacity SSD, and if it is only text-related, then the needs may differ. In this case, both of these SSDs are carrying 500GB capacity for you.

They both also work with SATA 6 Gb/s interface. Being released in July 2017, the WD Blue SSD is a bit older version as compared to the Samsung 870 Evo, which got released in January 2021.

Flash memory chips type and Cache:

The type of NAND flash memory chips used in these SSDs differ. It is 3D NAND for the WD blue SSD, while if we look at the Samsung 870 Evo, then the type is V-NAND.

Cache storage is not available with the WD blue, while you can have about 512 MB for the Samsung 870 Evo SSD.

Reliability in terms of TBW:

TBW, or the total bytes written, is important when considering SSD usage. This terabytes metric determines the number of TBs you are allowed to write using the warranty time period of the drive.

In this regard, Samsung 870 Evo stands to be more reliable with 600 TBW, and there is only a 560 TBW limit for the WD blue.


This is the most crucial factor when you are relying on a specific budget and still desire the best. This is also related to the required set of tasks that you wish to carry out with the particular technology you are spending on.

The price for a Samsung 870 Evo giving 500GB capacity of storage is around $59.99 on Amazon. It is $54.99 for the Western Digital 500GB WD. The price difference is noticeable and is as per your flexibility.

Read and Write:

Because we are talking about SSDs and drives, reading and writing speeds are very important. The read and write for the Evo 870 is 560/530 MB/s keeping in view the sequential requests, respectively.

On the other hand, if we talk about the WD Blue SSD, it provides around 560MB/s for its sequential read and a speed of up to 530MB/s for its sequential write requests collectively.

User rating:

Users are prone to speed and performance with much accuracy and reliability. They also want their technology to be adaptable and versatile with all the possibilities.

Users have given a 50% rating to WD blue SSD while it is changed for Samsung 870 Evo and is better with 60-70%.

Final Words:

SSDs have become a useful tool for people who like to keep their data stored permanently with a more reliable platform. The major advantage is that SSD includes no spinning and moving of its parts.

Both Samsung 870 Evo and the WD Blue SSD are rated as good experienced SSDs by the users, but in terms of performance, we can say that Samsung 870 Evo has made its mark.

Evo 870 also gives a high market share and gives better value and most of all, it is still affordable. If you are wishing for a less price, then you can go for the other one.


Is wd blue SSD compatible with macbook pro?

Yes, the wd blue SN550 NVMe SSD is very easy compatibility with the Macbook Pro when it comes to WD Blue SSD. This not only provides a direct source of application but it is also useful for adding up to about 1TB of storage to your Macbook Pro.
So, if you are running out of storage space consider using this useful SSD. However, as mentioned in the article above about the interface, it is compatible with Macs that work using SATA controllers.

How long does wd blue SSD last?

It supports a lifespan of around 400 TBW which cannot be truly reliable enough in certain cases. Usually, 10 years is a time span that we can say is suitable enough for many SSDs of WD if they are used in normal loads of work.

Does wd blue SSD have a dram cache?

No, it does not provide support to a DRAM cache and this lacking increases its competition with other relevant SSDs like Adata SP550 and the other discussed in the article as a comparison above Samsung 870 EVO.

Is the Samsung Evo 870 better than the 860?

Yes, as a whole if we look at the maximum sequential reading speed then it is noted that the EVO 870 is much faster as compared to the EVO 860. As EVO 860 supports 550 MB per second speed and EVO 870 gives 560 MB per second.
