Designed for creative professionals, the Pegasus32 R4 72TB 4-Bay Thunderbolt 3 RAID Array from Promise Technology delivers the speed, capacity, and protection needed for large projects and backups. Featuring four drive bays equipped with hot-swappable 18TB 7200 rpm SATA III 3.5" hard drives, the 72TB array has a maximum data throughput of 2800 MB/s. Its hardware-based controller supports RAID 0, 1, 1E, 5, 6, and 10 configurations, and the fan-cooled drives are pre-configured for RAID 5. Connectivity to your host system is established using a 40 Gb/s Thunderbolt 3 port that also provides up to 85W of charging power, while a second Thunderbolt 3 port may be used for daisy chaining and supports up to 15W of charging power. If your system doesn't support Thunderbolt 3, both ports are backward compatible with 10 Gb/s USB 3.2 Gen 2. There is also a DisplayPort 1.4 connector that supports 8K displays for large and highly detailed projects. The drives come pre-formatted for macOS 10.14 or later, but may be reformatted for Windows 10.
Buy based on the software ecosystem (e.g. Available from $4,599.
NAS (Network Attached Storage) devices run 24/7, making power consumption a steady, though low, cost. The real ongoing expense is replacing hard drives as they fail or filling empty bays to expand storage.
Common Failure Modes
Hard drive failure is the most common issue, which is why NAS uses RAID redundancy to prevent data loss. Fan failures and power brick deaths are the primary hardware issues for the enclosure itself.
Buy based on the software ecosystem (e.g., Synology DSM) and the number of drive bays you need for redundancy and future expansion. CPU power matters greatly if you plan to run media servers like Plex.
The NAS enclosure itself can last a decade. However, the hard drives inside are consumable and typically need replacing every few years depending on workload.
