Crucial BX500 1TB
Score: 67/100
Samsung 990 PRO
Score: 81/100Rankings
The Samsung 990 PRO 1TB is a high-performance PCIe 4.0 NVMe SSD delivering up to 7,450 MB/s read and 6,900 MB/s write speeds with strong security features. Its heatsink-less design and limited pSLC cache can limit sustained heavy workloads. Best suited for gamers, content creators, and professionals who need maximum PCIe 4 throughput on desktops or laptops with adequate cooling.
The Crucial BX500 1TB SATA SSD offers an affordable upgrade with decent sequential speeds and reliable TLC NAND. Its DRAM-less architecture leads to throttled sustained writes and limited random performance, making it suited for budget-conscious users upgrading from HDDs.

Professional reviewers acknowledge that the BX500 meets its advertised sequential speeds and offers a solid entry-level SSD experience, but they criticize the DRAM-less architecture for causing sustained write speeds to drop to roughly 100 MB/s and for delivering weak random IOPS, making it unsuitable for demanding workloads.
Everyday users generally praise the noticeable boost in boot times, file access, and battery life after upgrading from a hard drive, while recurring complaints focus on performance throttling during prolonged writes and the lack of high-end features.
Professional reviewers commend the 990 PRO for its exceptional speed, gaming-optimized random performance, and strong reliability, while noting the smaller DRAM cache and lack of a heatsink as potential drawbacks under heavy sustained loads.
Everyday users praise the drive's blazing speed and security, but note concerns about the smaller DRAM cache and possible throttling without a heatsink.
