G Speed shuttle XL maximum capacity

The **G‑Technology G‑SPEED Shuttle XL** is an 8‑bay, portable hardware RAID system designed for high‑performance workflows. The maximum capacity varies based on model:

* **Thunderbolt 2 (legacy)**: Up to **112 TB** when equipped with 8×14 TB enterprise HDDs ([bhphotovideo.com][1]).

* **Thunderbolt 3**: Official WD/TB3 models support configurations up to **112 TB**, with some customs/configurations reaching **144 TB** .

* **Older estimates** show factory configurations topping out at **80 TB** (8×10 TB) on earlier TB2 units .

### ✅ Summary Table

| Interface | Max Raw Capacity | Notes |

| ------------- | ----------------- | -------------------------------------- |

| Thunderbolt 2 | 112 TB | 8×14 TB drives ([bhphotovideo.com][1]) |

| Thunderbolt 3 | 112 TB (official) | Some setups (custom) go to 144 TB |

---

### 🔧 Additional Details

* **RAID support**: Configurable in RAID 0, 1, 5, 6, 10, and 50 (JBOD in TB3 adds flexibility) ([amazon.com][2]).

* **Drive compatibility**: Uses 7200 RPM enterprise-class SATA HDDs. Replacing drives with higher capacity models may expand total raw capacity (up to the limits above).

* **TB3 models** also offer higher sustained transfer speeds (up to \~2000 MB/s).

---

### ⚠️ Notes on "Maximum Capacity"

* Capacity is dependent on **drive size**, **RAID configuration**, and what the **interface supports**.

* RAID overhead (especially RAID 5/6) reduces usable capacity relative to raw totals.

* Official WD spec caps at **112 TB**, but some verified custom builds show up to **144 TB** in TB3 units.

---

**Bottom line:**

* For **Thunderbolt 2**, the official max is **112 TB**.

* For **Thunderbolt 3**, you can expect up to **112 TB**, with select setups reaching **144 TB**.

* Real-world usable capacity will be slightly lower once RAID overhead is accounted for.
