ARC‑8050T5U‑12N SAS/SATA/NVMe 12 0/1/10/5/6 AI/ML datasets, 8K/12K workflows, extreme throughput

2. Thunderbolt 5 Architecture

Thunderbolt 5 provides up to 80 Gbps standard and 120 Gbps Bandwidth Boost, enabling Areca RAID systems to deliver internal‑class performance externally.

  • Up to 12 GB/s real‑world throughput
  • Dual‑path bandwidth for storage + display
  • Backward compatible with TB3/TB4 (at reduced speed)
  • Ideal for NVMe RAID and RAID 60 HDD arrays

3. Areca Hardware RAID Engine

All ARC‑8050T5U models use Areca’s enterprise RAID‑on‑Chip (ROC) with dedicated parity acceleration and DDR cache.

Key Features

  • Hardware RAID 0/1/10/3/5/6/30/50/60
  • Dedicated XOR/LDPC parity engines
  • Up to 4GB DDR4 cache
  • Write‑back caching with supercap/BBU protection
  • Full web‑based management (ArcHTTP)
  • CLI support for macOS, Windows, Linux

Unlike software RAID enclosures, Areca RAID systems do not rely on host CPU resources.

4. Performance

4.1 SAS/SATA RAID Performance

  • 7–8 GB/s sustained (12‑bay RAID 60)
  • 5–6 GB/s typical (8‑bay RAID 5/6)
  • Ideal for large HDD archival arrays

4.2 NVMe RAID Performance

  • 10–12 GB/s (8–12 NVMe drives)
  • 6–8 GB/s (6 NVMe drives)
  • Perfect for 8K RAW, EXR, VFX, AI/ML

4.3 Rebuild Performance

  • NVMe RAID rebuilds: 3–6 GB/s
  • SAS/SATA RAID 6 rebuilds: 120–180 MB/s
  • RAID 60 rebuilds: 20–30% faster
