MEMXPRO's Ruler SSD E1.S PT33 series are E1.S short-type SSDs that meet the Enterprise Data Center Solid State Disk Form Factor (EDSFF) standard and are ptimized for 1U servers. E1.S features small footprints, flexibility, and scalability that boost NVMe performance through higher density and thermal efficiency. MEMXPRO Ruler E1.S SSD fits vertically in a 1U chassis. Supporting more SSDs per rack achieves high-density storage capacity and I/O performance, while the EDSFF universal connector standard enables better system scalability. The low-power output and heat spreader solution of Ruler SSD E1.S PT33, together with optimized cooling and airflow management in the new generation of rack servers, attains the best balance between heat dissipation and performance. It also improves energy efficiency and signal integrity.
