. Preliminary performance estimates indicate:

• Sequential read speed: up to 7,400 MB/s
• Sequential write speed: up to 3,200 MB/s
• Random read performance: up to 930K IOPS
• Random write performance: up to 25K IOPS

Unprecedented Endurance and Efficiency

One of the most notable features of the D5-P5336 is its unlimited Random Write endurance for five years, making it ideal for AI training and large-scale data processing workloads 3
