Western Digital WDS400T4B0E 4TB Blue SN5000 NVMe SSD Gen4

The Western Digital WD Blue SN5000 WDS400T4B0E is a 4TB PCIe Gen 4 x4 NVMe SSD in M.2 2280 form factor, rated at 5,500MB/s sequential read and 1,200TBW write endurance. Those numbers deserve interpretation: 5,500MB/s means a 50GB 4K video project file transfers from this drive to another Gen 4 storage device in under 10 seconds. The 1,200TBW rating at 4TB capacity translates to a 0.30 DWPD (Drive Writes Per Day) over a 5-year warranty period — sufficient for the heaviest creative workflows. The nCache 4.0 SLC caching layer ensures that the rated write speeds are what you'll see during typical large-file operations, not theoretical numbers that collapse the moment you push beyond a small buffer. The NAND is TLC (Triple-Level Cell), the industry standard for capacity-tier consumer and prosumer drives, balancing cost-per-gigabyte with adequate endurance.

The SN5000 4TB is engineered for content creators who have outgrown smaller NVMe drives and need a single-slot solution for active project storage. A videographer managing a 4K or 6K project library, a 3D artist working with large scene caches, or a photographer ingesting RAW files from multi-card shoots will find the combination of 4TB capacity and Gen 4 throughput eliminates two common workflow bottlenecks simultaneously: storage space anxiety and asset load times. The drive sits clearly above the budget QLC tier — where sustained write performance degrades significantly under load — without requiring a premium investment in enterprise or enthusiast-grade TLC alternatives. It's not a RAID replacement or an archival solution; it's a primary active-project drive for creative workstations where the M.2 slot is the right form factor.
