Why consider this model?

  • A fit to assess when six native SATA positions, built-in 2.5GbE and a documented memory-upgrade path matter more than an 8 GB starting configuration.

Tradeoffs to weigh

  • The documented TS-664-4G starts with only 4 GB RAM, below QNAP's stated 8 GB minimum for QuTS hero; no matching current U.S. Official Store package or SKU was confirmed, and all data drives remain separate.
