Thunderbolt 5 Professional Storage
The ARC-8050T5U provides high-bandwidth Thunderbolt 5 connectivity between the RAID system and compatible workstation.
This makes the system particularly well suited for workflows involving very large media files and projects, including:
- 4K video editing
- 6K video production
- 8K video workflows
- Professional photography
- RAW photo libraries
- Video post-production
- Content creation
- Digital media production
- Large project storage
- Workstation expansion
- High-capacity backup
- Data archiving
Hardware RAID
The ARC-8050T5U provides hardware RAID functionality, allowing the eight installed drives to be configured according to the user's requirements.
Depending on the RAID level selected, the system can be optimized for:
- Maximum usable capacity
- Data redundancy
- Drive-failure protection
- Storage performance
- Capacity and redundancy balance
Actual usable capacity depends on the RAID level, filesystem, formatting, and controller configuration.
Approximate RAID Capacities
With eight 22TB drives:
| RAID Level | Approx. Raw Usable Capacity* |
|---|---|
| RAID 0 | 176TB |
| RAID 5 | 154TB |
| RAID 6 | 132TB |
| RAID 10 | 88TB |
*Before filesystem overhead and decimal-to-binary capacity differences.
22TB Spare Drive Included
This configuration includes a ninth matching 22TB Ultrastar DC HC570 SAS drive.
The spare drive provides a convenient replacement for one of the eight installed drives in the event of a failure. Because the spare matches the installed drives, customers do not need to immediately source another compatible 22TB enterprise SAS drive.
8 drives installed + 1 matching spare = 9 drives included.
