The M.2 110mm form factor was popular in hyperscale data centers due to its low-cost structure, flexibility, and scalability of multiple drives per server. However, it faced challenges in terms of hotplug/serviceability, thermals and overheating, and scaling to high capacities. E1.S addresses these issues while maintaining a small form factor.
