Overview
The Samsung BM1743 is Samsung's QLC-based read-intensive enterprise drive, and the MZWMO30THCLF-00AW7 is the 30.72 TB U.2 build. QLC packs four bits per cell, which is what allows 30 TB in a 7 mm 2.5-inch envelope without the cost of TLC at the same density.
The trade-off is write endurance: the drive is rated 0.3 DWPD, which is entirely adequate for read-dominant workloads - model and dataset staging for AI inference, media libraries, CDN caches and analytics scans - but not for write-heavy logging or virtualisation datastores. Matching the drive to a read-dominant profile is the single most important selection decision with QLC enterprise parts.
The 7 mm U.2 profile matters in dense 1U and 2U NVMe bays where 15 mm drives restrict airflow and drive count.
Key Benefits
30.72 TB in 7 mm U.2: maximum density in standard 2.5-inch bays. QLC economics: lowest cost per terabyte in the Samsung enterprise line. Gen4 x4: 7,000 MB/s read for cache and staging tiers. Read-optimized: designed for large-footprint read-dominant workloads.
Applications
AI model and dataset staging, CDN and media caches, analytics and data-lake scan tiers, backup and cold-data repositories, and object-storage nodes where reads dominate writes.
