Western Digital Blue vs Green SSD

Western Digital has two SSD lines, one being the Green series and the other being the Blue series. Both lines are lower in price per gigabyte, so which line should you choose? The Green line offers more space with bigger drives, but the Blue line offers faster read and write speeds and is less power-hungry than their Green siblings.

But before you make your decision, take a look at this comparison of Western Digital Blue vs. Green SSDs to help you determine which line makes more sense for your needs.

What is Western Digital Blue?

The Western Digital Blue is a SATA III hard drive with a spindle speed of 5400 RPM. It has a capacity of 1TB and is 6.35 cm in height. The average seeks time for this drive is 12ms.
The pros of Western Digital Blue are that it is affordable and has a high capacity. The cons are that it is a little slower than some of the other drives on the market and does not have an NVMe interface.


Western Digital Blue drives are known for their affordable price and decent performance. However, there are some disadvantages to consider before buying one.

  • First, Western Digital Blue drives tend to be noisy. This can be a problem if you’re trying to use your computer in a quiet environment.
  • Second, they don’t always offer the best performance. While they’re usually fine for everyday tasks, more demanding users may be disappointed.
  • Finally, Western Digital Blue drives don’t have special features or extras. If you’re looking for something fancy, you’ll need to look elsewhere. But if you just need a primary drive that gets the job done, a Western Digital Blue should suffice.

What is Green SSD?

When it comes to choosing a solid state drive (SSD), there are a lot of different options on the market. Western Digital (WD) and Samsung are two of the most popular brands. WD offers two lines of SSDs: the WD Blue and the WD Green. So, what’s the difference between them?

The significant difference is in their performance characteristics. The WD Blue line is aimed at mainstream use cases requiring everyday performance for activities like web browsing, emailing, streaming media, and office work. On the other hand, the WD Green line has been designed for more intensive use cases like gaming or video editing where consistency and reliability are essential requirements. The bottom line is that if you want an affordable SSD that can be used for everyday tasks but still provides better performance than traditional hard drives, go with the WD Blue.


As the world progresses, more and more people are becoming aware of the importance of sustainability. Businesses are looking for ways to reduce their carbon footprints, and consumers are interested in buying products that will help them. One way to green your business or home is to switch to using SSDs. Here are some of the advantages of using a green SSD:

  1. Lower power consumption – since SSDs don’t have moving parts, they use less power than traditional HDDs. This can lead to significant energy savings, which is good for your wallet and the environment.
  2.  Generate less heat – because they use less power, SSDs also generate less heat. This can prolong the life of your computer components and save you money on cooling costs.


Solid-state drives are becoming more popular as the prices continue to drop and the capabilities increase. However, some disadvantages to green SSDs should be considered before making a purchase.

One of the most significant disadvantages is the limited storage capacity compared to traditional hard drives.

  1. Green SSDs typically have lower capacities than their standard counterparts, which can be a problem for users who need to store large amounts of data.
  2. Another downside is that green SSDs are slower than traditional hard drives. This can be frustrating for users looking for the fastest possible performance from their computers.
  3. Finally, green SSDs typically have shorter lifespans than traditional hard drives. This means they will need to be replaced more often, which can add to high costs.

Difference Between Western Digital Blue and Green SSD

The WD Blue and Green SSDs are both SATA III drives with a 6 Gb/s data transfer rate. The WD Blue has a read speed of up to 545 MB/s and a write speed of 525 MB/s, while the WD Green has a read speed of up to 540 MB/s and a write speed of 410 MB/s. So, the WD Blue is faster than the WD Green. If you want an SSD that performs better for reading speeds and writes, then get the WD Blue. If you’re not too concerned about performance and can live with slower speeds on reads and writes, then go for the cheaper WD Green.

Capacity: Western Digital Blue vs. Green SSD

The WD Blue is available in capacities ranging from 250GB to 4TB, while the WD Green is only available up to 2TB. The WD Blue is slightly more expensive than the WD Green in terms of price per gigabyte. However, it should be noted that the more minor capacity results in a lower cost per GB for the WD Green. Additionally, the WD Blue offers significantly faster read and write speeds.

Storage Speed: Western Digital Blue vs. Green SSD

Here’s a quick comparison of storage speed between the Western Digital Blue and Green SSDs. The WD Blue offers read speeds up to 545 MB/s and write speeds up to 525 MB/s, while the WD Green provides read speeds up to 540 MB/s and write speeds up to 450 MB/s. So, the WD Blue is slightly faster than the WD Green in both read and writes speeds.

Interface: Western Digital Blue vs. Green SSD

Regarding solid-state drives, there are two main types of interface: SATA and NVMe. SATA is the older interface, and it’s the one you’ll find on most laptops. It’s slower than NVMe, but it’s also cheaper. NVMe is the newer standard, and it offers much faster speeds. It’s more expensive, but it’s worth the extra cost if you’re looking for speed. The real benefit of an NVMe drive is that it uses less power than a SATA drive. That means your laptop battery will last longer when using an NVMe drive.

The newest interface type on the market is PCIe, which can provide up to 1GB/s transfer rates! It’s not currently as popular as SATA or NVMe, so that prices can be a little high right now. Still, this technology looks promising, and we might see some pretty fast laptop storage in the future!

Endurance (Drive Writes Per Day): Western Digital Blue vs. Green SSD

If you’re looking at Western Digital drives, you may wonder what the difference is between their Blue and Green SSD lines of SSDs. Here’s a quick rundown:
The main difference between the two is in terms of endurance, or how many drives writes per day, they can handle. For example, a WD Blue drive with 250GB capacity can withstand up to 80TB of writes over its lifetime, while a Green drive with the same capacity can only take 40TB.

Form Factor: Western Digital Blue vs. Green SSD

The WD Blue and Green SSDs both come in the 2.5-inch form factor. This is the standard size for laptops and many desktop computers. The 2.5-inch form factor allows for easy installation into various devices. The Blue series can only be installed vertically, while the Green series can be installed either vertically or horizontally. Both series are available with SATA III interfaces and an M.2 interface that supports PCIe Gen 3 x4 lanes, allowing it to have up to four times the speed of SATA III on some models.

The Western Digital Blue series is available in capacities ranging from 250GB to 6TB, while the Green comes in 120GB up to 1TB capacity options. Additionally, there are significant differences in performance between the two series. For example, the WD Blue 5400 RPM HDD has a performance rating of 310 MB/s, whereas the WD Green 5400 RPM HDD has a performance rating of 240 MB/s. These differences should be considered when deciding which type of drive to purchase.


Their target market is the most significant difference between these two types of SSDs. The WD Blue is designed for general use, while the WD Green is meant for power users. However, both drives offer great speed and reliability. So, which one is right for you? It all depends on your needs.
