Introduction

UDM 1U is small form factor that electrically complies with High-speed USB 3.0 interface. Tailored for the 1U server, the new series boasts upgraded speeds and a doubling of capacity. The minimum height is only 22.4mm, enhancing the air ventilation inside the 1U chassis.
The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file formats and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.
