0B40374 WD Ultrastar DC SS530 7.68TB SAS 2.5" Server SSD

High-Density 2.5in SAS Enterprise SSD with SED Security for Server Bays using the 0B40374

The 0B40374 is a 7.68TB 2.5in SAS hot-swap enterprise SSD engineered for high-availability server storage tiers where predictable latency and secure lifecycle management are mandatory. Designed for read-intensive and mixed workloads, it delivers up to 2150 MB/s read and 2120 MB/s write, aligning well with modern SAS backplanes and RAID/HBA architectures commonly deployed in 24x7 datacenters.

Built on TLC NAND, the 0B40374 balances capacity with endurance at 1 DWPD for 5 years (15,050 TBW), making it suitable for boot pools, caching layers, and frequently accessed application datasets. SAS connectivity supports consistent multi-initiator behavior and robust error handling in shared storage designs, while hot-swap capability simplifies service operations in dense chassis. Power Loss Protection helps protect in-flight data during unexpected outages, reducing recovery time and safeguarding metadata consistency.

Why Choose the 0B40374?

The 0B40374 provides an enterprise-focused density-to-performance profile for 2.5in drive bays, enabling capacity scaling without sacrificing serviceability. With up to 440K 4K random read IOPS and strong sequential throughput, the 0B40374 supports latency-sensitive reads while maintaining operational stability through 2.5M hours MTBF and datacenter-oriented power characteristics. Integrated SED features enable compliant deployment across secure domains with controlled decommissioning processes.
