Overview

 

The ST4R-B32 is a 4-bay USB-C DAS featuring two independent 2-drive hardware RAID groups.

 

Drives 1–2 form G1 and Drives 3–4 form G2. Each group can be independently configured as RAID 0, RAID 1, BIG, or JBOD and accessed simultaneously through a single USB-C connection.

 

A typical configuration is:

 

● G1 RAID 0 — Active Projects

 

● G2 RAID 1 — Protected Project Data

 

With USB 3.2 Gen 2x2 up to 20Gb/s, support for up to 30TB per drive, hot-swappable trays, system monitoring, and Easy Data Vault support, the ST4R-B32 provides flexible local storage for creative, workstation, and SOHO workflows.

 

Why ST4R-B32?

 

● Two Independent RAID Groups

 

Run two separate 2-drive hardware RAID groups in one enclosure.

 

● Different RAID Modes

 

Configure G1 and G2 independently as RAID 0, RAID 1, BIG, or JBOD.

 

● Two Storage Roles

 

Use each RAID group for a different workflow without adding a second enclosure.

 

● One USB-C Connection

 

Access both RAID groups simultaneously through one host connection.

 

Dual RAID Architecture

 

One System. Two Independent Storage Groups.

 

RAID Group 1	RAID Group 2
Drive 1 + Drive 2	Drive 3 + Drive 4
RAID 0	RAID 1
Active Projects	Protected Project Data

 

G1 and G2 can each be independently configured as RAID 0, RAID 1, BIG, or JBOD.

 

Both groups are accessible through the same USB-C connection.

 

Typical Single-Array 4-Bay RAID vs. ST4R-B32

 

Typical Single-Array 4-Bay RAID	ST4R-B32
Four drives operate as one RAID array	Two independent 2-drive RAID groups
One primary RAID configuration	Different RAID modes for G1 and G2
Designed around one storage pool	Designed around two storage roles
One primary workflow	Multiple storage workflows

 

ST4R-B32 is designed for users who need multiple storage workflows from one 4-bay DAS rather than one large RAID array.

Common Deployment Applications

 

1. Creative Workstation

 

G1 RAID 0

 

Active Editing Workspace

 

G2 RAID 1

 

Protected Project Data

 

Use performance-oriented working storage and protected project storage in the same enclosure.

 

2. Photography & Video Studio

 

G1 BIG

Import & Media Library

 

G2 RAID 1

Completed Project Data

 

Keep different stages of the production workflow separated within one storage system.

 

3. SOHO Workstation

 

G1 RAID 1

Business Data

 

G2 RAID 1

Secondary Local Data

 

Maintain two independently managed storage groups for different business workloads.

 

4. Mobile Photo & Video Workflow

 

Use Easy Data Vault with compatible USB-C iPhone and iPad devices for direct photo and video backup.

 

RAID Modes

 

Mode	Best For	Note
RAID 0	Performance / active projects	No redundancy
RAID 1	Protected data	Single-drive redundancy
BIG	Combined capacity	No redundancy
JBOD	Independent drives	No redundancy

 

RAID is not a substitute for backup. Maintain a separate backup of important data.

 

Product Positioning

 

ST4R-B32 is built for workflows that need more than one storage role from a single 4-bay DAS.

 

Run active project storage, protected data, media libraries, or secondary local storage side by side—each with its own RAID configuration and accessible through one USB-C connection.

 

One Enclosure.

Two Storage Roles.

Built for Modern Workflows.

 

Frequently Asked Questions (FAQ)

 

Q1. What RAID modes are supported?

 

A: Each RAID group supports RAID 0, RAID 1, BIG, and JBOD.

 

Q2. Does ST4R-B32 support RAID 5 or RAID 10?

 

A: No. ST4R-B32 uses two independent 2-drive RAID groups.

 

Q3. Can G1 and G2 use different RAID modes?

 

A: Yes. For example, G1 can use RAID 0 while G2 uses RAID 1.

 

Q4. Can both RAID groups be accessed simultaneously?

 

A: Yes. Both groups can be accessed through the same USB-C connection.

 

Q5. What happens if one RAID group is rebuilding?

 

A: The other RAID group can remain accessible while one group is rebuilding. Performance may vary during simultaneous operations.

 

Q6. What is the maximum capacity?

 

A: Up to 30TB per drive, providing up to 120TB of raw capacity.

 

Q7. Can different drive capacities be used?

 

A: Yes, but usable RAID capacity may be limited by the smaller drive within each group.

 

Q8. Can Easy Data Vault recognize both RAID groups?

 

A: Yes. Dual-volume recognition is supported when both volumes are formatted as exFAT on compatible USB-C iPhone and iPad devices.

 

Q9. Does USB-C automatically provide 20Gb/s?

 

A: No. The host must specifically support USB 3.2 Gen 2x2 20Gb/s.

 

Q10. Is RAID 1 the same as backup?

 

A: No. RAID 1 protects against a single-drive failure but does not replace a separate backup.

 

Performance test result for reference. The test result will vary depend on the test environment.
