Western Digital WD Blue SN550 (500 GB NVMe)

SSD’s are the Pinnacle of storage devices for consumer computers. If you are upgrading from a hard disk drive, then you are on par with the trend. It’s no secret how much SSD’s can improve your performance. From boot up, reading and writing data, and launching applications – everything is instant. And unlike HDD’s these won’t get slower as your storage gets fuller.

Our pick is the Western Digital WD Blue SN550 (500 GB NVMe). When it comes to storage devices, Western Digital is a big name in the industry. They are one of the best in the market and have been manufacturing storage devices for quite some time. The model we are reviewing has over 13,000+ ratings with 5 on 5 stars. It is marked as Amazon’s Choice and is an excellent product for under $60. Read through our full review to see if it is powerful enough to replace your old storage unit. Also, if you are interested in portable SSD devices, read our review on the SAMSUNG T5 Portable SSD 1TB. This product is also very highly rated and is used by most professionals.


The WD Blue SN550 comes with a single-sided M.2 2280 form factor with a blue PCB. The controller and the firmware that powers the SSD are designed by WD. You won’t get a DRAM but do offer an SRAM on the controller for tasks. The Nand flash disk is made from San Disk. Quick Note, Western Digital bought SanDisk. So the updated WD drives come with at least some of its components made by SanDisk.

The WD Blue SN550 does perform live up to the specs it is supporsed to operate at. However, the increased performance is just marginally better than what you would get from a SATA SSD. The difference is not that significantly noticeable as what you would see between HDDs and SSD. But still, it’s a worthy upgrade judging the fact it’s from Western Digitals instead of some unknown brand. Western Digital storage devices are known to be very reliable. If you do need more performance, buying the WD Black variant would be more preferable. That will give you the best performance from what you will get from WD. We did notice the boot time on Windows 10 to be considerably faster than a SATA SSD. The gaming performance and heavy app loading times are also better.

WD Blue vs. Black

You will get this SSD in either the blue or the black variant. If you are a general consumer then we highly recommend you stick to these two offerings. There are other variants denoted by color, such as WD green, red, purple, and so on. Those have their tradeoffs and are intended for specific users.

The Blue variant is a budget-friendly SSD. It is also the most common one most people purchase. If you are a hardcore gamer, then the Black series might be for you. It offers the maximum performance Western Digital can offer. However, it will cost you more money, so check on it before making your purchase.

Don’t understand what’s SATA or SSD?

Even if you use computers since childhood, you may still not understand what these terms mean. It is very common for non-tech people. So If you are new to computer hardware, then here’s a quick rundown of these storage types.

  • Serial Advanced Technology Attachment or SATA for short is the most common type of storage unit. These are present in most computers used today. These HDDs are mechanical, meaning they have moving parts inside. The speed unit is measured in RPM (revolutions per minute). Usually, you will get 5400 or 7200 RPM hard drives. The higher the number, the speedier the drive will be. These hard drives tend to last for many years, but also tend to break at the end of their life cycle, or if it receives damage.
  • SSDs or Solid State Drives are also known as Flash-memory-based storage systems. SSDs tend to be very expensive as compared to HDDs and also offer lower storage capacity. The primary advantage to SSDs is that they don’t have any moving parts, works extremely fast, low heat output, and can endure solid impacts. Also, the operation is dead silent.

Want to upgrade yourself?

Upgrading the SSD is a very easy task, even for newbies. However, knowing what SSD will fit your system can overwhelm some people. This model of WD drive has the number 2280. This number is important, as it defines what SSD it is and what system it will fit into.

The first 2 digits indicate the width of your SSD. The last 2 digits are for the length measurement. The unit is measured in millimeters. If you have a mini PC then you will need an SSD with a smaller footprint, thus, keeping this number in check is very important.
