The WD Blue SN550 SSD offers a range of storage capacities, from 250 GB to 2 TB, and is known for its fast NVMe performance and affordability. Users appreciate the 5-year warranty, which adds to its appeal. However, some users have reported that the SSD can get very hot and may require additional cooling.

Despite these issues, the SSD is generally considered a great choice for those seeking a balance between cost and performance.
Pros
Cons
nice choice for 9800! NVMe warranty 5 years it gets very hot and needs cooling.  By_Sg: use WD WDS100T2B0C less than month |
fast, cheap NVMe. I bought it for the system. After 2 months, the computer started to lag for 3-5 seconds. Within 6 months of use, it increased to once an hour. I started searching for the root of the problem, it turned out it's dropping the speed.  Fil Aleksey: use WD WDS250G2B0C few months |
