Rating: 4.9 (13 reviews)

The WD Blue SN550 NVMe SSD offers up to three times higher performance compared to a high-end SATA SSD.

See full description See full description

Communication Protocol

Most SSDs use SATA III or PCI Express.

Almost all 2.5" SSDs connect via SATA III while most M.2 SSDs connect via PCI Express.

PCI Express connection offers higher speeds, but this is mainly noticeable in demanding applications (high-resolution video processing, transferring large files, etc.) and is not necessary for everyday use.

PCI Express 3.0

Connecting to the PCI Express expansion port of the motherboard. Equally popular way of connecting SSD hard drives directly to the motherboard. This connection offers the highest speeds.
Write Speed

Indicative size for the maximum speed of the hard disk during data recording. The larger the size, the faster the data recording.

For an SSD that uses the SATA III protocol, the average recording speed is 300MB/s, while for one with NVMe it is 1200MB/s.

These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.
Read Speed

Indicative size for the maximum speed of the hard disk during data reading. The larger the size, the faster the data reading speed.

An average reading speed for an SSD using the SATA III protocol is 600MB/s, while for one with NVMe it is 2000MB/s.

These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

I have been using this disk for a year, it has about 30 games installed from the Steam library, all of them play perfectly. It's been a good purchase so far

It has a very good performance/price at 90€.

It is gen 3, however, at the moment it doesn't seem to excel in anything compared to gen 4 in real situations.

Fastest and reliable so far. I wanted to go with Samsung because my previous two SSDs were Samsung and I had no complaints. WD proved itself and saved me a lot of money. Highly recommended!

The disk offers exceptional performance, especially in I/O of small file sizes, which is what the average user wants. In 4K I/O size, it even surpasses the Gen 4 VP4100 from Patriot, which is much more expensive but theoretically better!

The only problem with the disk is the company that manufactures it. Unfortunately, Western Digital once again shows us that it is unworthy of trust, as it has made a downgrade here as well, just like in many of its other disks.

Now the disk uses lower quality QLC NAND compared to the TLC it had, resulting in a noticeable drop in performance once it exhausts the 12GB SLC cache it carries.

For the average user, the performance has not changed, since very few everyday users will be able to exhaust the SLC cache during their writes, which means it is still worth buying. Whether you want to support such practices with your purchase is another matter...

Having already a Samsung Evo 860 plus 500GB for the basics (Windows, programs) and wanting a second NVME again to load games, documents, and images so as not to fill up the main disk and start experiencing performance drops.
Impressions so far are very good, the temperature is lower than the Samsung under full load and idle, the speeds are exactly what WD promises!
It was installed in a computer with an MSI Z490 A pro motherboard with an i5 10600K and 16GB RAM.
*update 18/01/2022: it continues to perform flawlessly and has not presented any issues despite constantly deleting and writing files and games

I trust this specific company. I had a 2.5-inch blue 500GB disk which was excellent. However, I replaced it with this affordable diamond and saved a SATA cable for data and a power cable. I also added an ekwb cooler and haven't put pressure on it during the month that I have had it. But when it copies files of 50GB or 100GB, the temperature ranges from 37 to 39 degrees Celsius. Also, it has a 5-year warranty! Everything is excellent, I was and will be satisfied with Western Digital. Just a clarification for those planning to install a cooler, they should know that there is nothing behind it as you can see in the photos, so the surface is flat. However, in the front where the two chips are, there is a height difference of 0.5 millimeters in one and 1 millimeter in the other, in terms of the disk's surface. I understood this because the cooler didn't sit well, so I put the 1 millimeter on the low chip and the 0.5 millimeter on the thin one, and everything is fine. Excellent disk, an economical tool!

In real conditions, I see around 2GB/s with 2.3GB/s read and 1.2GB/s write. In synthetic tests, the write speed goes up to 1.8GB/s.

- During stress tests, temperatures range from 40 to 45 degrees Celsius, so no cooling is needed.

- The memory is TLC instead of QLC*, which is commonly used by manufacturers at this price point.

- It doesn't have DRAM and uses the system's PCIe bus. This is not a problem for NVMe SSDs like it was for SATA SSDs, so it is not considered a negative aspect.

- After 8 months of use, I haven't encountered any issues. I will update the review for any new developments.

- At the price of 140€ that I bought the 1TB model, I am satisfied.
At the current price of 122€ as I am writing this, it is super, especially considering that for the same amount of money, you can get a SATA SSD with 1/3 of the performance and QLC.

*QLC = 4 bits per cell. TLC = 3 bits per cell. The difference is that TLC can withstand 2 to 3 times more writes than QLC, resulting in a longer lifespan.
