72 out of 100 medium confidence 12 reviews

The WD Blue SN5000 is generally well-received, praised for its large SLC cache, good performance, and value, especially as a secondary or game drive. However, one unit arrived dead, and some users note it runs hot and lacks DRAM, which may affect performance in some scenarios. Overall, it's a solid budget NVMe SSD for most users.
