Sabrent Rocket Q4 2 TB (SB-RKTQ4-2TB)
Product-specific catalog record for the manufacturer code below. Performance figures are manufacturer-rated values, not independent test results.
IDENTIFY THE EXACT SKU: Compare the full MPN, label suffix, form factor, firmware and any OEM/security code before applying these notes. Family variations, capacity changes and factory thermal assemblies can materially change ratings and compatibility.
Manufacturer-identified specifications
| Product / MPN | Sabrent Rocket Q4 2 TB (SB-RKTQ4-2TB) — SB-RKTQ4-2TB |
|---|---|
| Capacity / form factor | 2 TB; M.2 2280, bare module. |
| Interface / lane width | PCIe 4.0 x4. |
| Protocol | NVMe 1.3. |
| Rated performance / endurance | Up to 4,800 MB/s sequential read and 3,600 MB/s sequential write; 400 TBW for 2 TB SKU. |
| Heatsink / revision caveat | Bare module; separate cooling accessories may be offered. Avoid installing a conflicting board cover or aftermarket sink; sustained write speed also depends on QLC cache state. Rocket Q4 is a QLC product and distinct from Sabrent Rocket 4/4 Plus TLC variants. Figures are for SB-RKTQ4-2TB; lower-generation hosts negotiate down. Confirm exact SKU, firmware and current manufacturer warranty registration terms. |
Compatibility, installation & service
- Check for PCIe/NVMe M.2 2280 signaling, x4 lane support, UEFI boot and board thermal-pad clearance. Follow Sabrent’s exact model instructions for any heatsink or firmware work. Make and verify a backup before migration; monitor health and plan for lower sustained write throughput after cache exhaustion.
- Rocket Q4 is a QLC product and distinct from Sabrent Rocket 4/4 Plus TLC variants. Figures are for SB-RKTQ4-2TB; lower-generation hosts negotiate down. Confirm exact SKU, firmware and current manufacturer warranty registration terms.
- Confirm host boot mode, OS NVMe support, CPU lane generation, socket length/keying, power and controller/backplane qualification from the system manual; physical fit alone does not establish compatibility.
- Before drive replacement, check backup integrity, encryption keys, firmware settings, recovery media and array rebuild plans. Use electrostatic-discharge precautions and never hot-remove unless the host documentation explicitly supports it.
