Pros & Cons

👍 Pros

  • Delivers robust sequential read and write throughputs of over 601 MB/s and 516 MB/s respectively
  • Features a space-saving design with a shallow depth of just 327.5 mm when server handles are installed
  • Equipped with dual 1GbE ports that support both network failover for reliability and load balancing for performance
  • Offers plug-and-play network upgrade modules for easily adding 10GbE RJ-45 ports, enhancing future network speed
  • Designed for rackmount installations, making it suitable for professional IT environments

👎 Cons

  • As a diskless NAS, hard drives are not included and must be purchased separately, increasing overall cost
  • The rackmount form factor may not be ideal for home users or those without dedicated server space
  • While upgradeable to 10GbE, the base unit only includes 1GbE ports, which might be a bottleneck for some
  • Users need to budget for the additional cost of network upgrade modules if 10GbE speeds are desired
  • The "space-saving" depth may still be considerable for exceptionally shallow rack cabinets
