Crucial MX500 500GB
Score: 79/100
Western Digital WD Green
Score: 63/100Rankings
The Crucial MX500 500 GB is a 2.5-inch SATA SSD that delivers near-maximum SATA-III speeds, includes a 256 MB DRAM cache and AES-256 hardware encryption, and offers 180 TBW endurance with a 5-year warranty. Its drawbacks are the inherent speed ceiling of SATA and occasional write-performance throttling under heavy mixed loads. It is best suited for budget-conscious desktop or notebook upgrades seeking reliable, secure storage.
The WD Green 1TB SATA SSD offers up to 545 MB/s sequential reads with ultra-low power consumption, making it a cost-effective choice for laptops and secondary storage. Its DRAM-less architecture and modest 400 TBW endurance limit performance for demanding tasks, and it's less suited as a primary boot drive. Best for budget-conscious users needing basic storage and long battery life.

Professional reviewers consider the MX500 an ideal HDD replacement, praising its efficient SM2258 controller, strong sequential and random performance, and robust security features. However, they note that its mixed-workload write speeds and 4K random read numbers fall short of some competitors, and the SATA interface limits its appeal for high-performance scenarios.
Everyday users overwhelmingly praise the MX500 for its noticeable boost in boot speed, system responsiveness, and ease of installation, especially valuing the included cloning software.
Professional reviewers position the WD Green 1TB as a budget-oriented SATA SSD that excels in power efficiency and price, but its DRAM-less design and modest endurance make it unsuitable for high-performance or write-heavy scenarios.
General users praise the drive for its rapid game loading, smooth everyday performance, and easy installation, seeing it as a solid value for a 2 TB capacity. Recurring concerns revolve around thermal throttling without a heatsink and occasional slowdowns during long write operations, especially for those expecting flagship-level consistency.
