## Performance

The 4 TB Sabrent Rocket 5 reaches sequential read speeds up to 14,000 MB/s and sequential writes up to 11,000 MB/s over PCIe 5.0 x4. Random performance peaks at approximately 1,400K read IOPS and 1,800K write IOPS. With all eight NAND channels fully populated, the 4 TB model delivers the most consistent performance across the Rocket 5 family.

The large SLC cache buffer at 4 TB absorbs sustained write bursts for extended periods before transitioning to native TLC writes, which themselves remain strong thanks to the high die count. In practice, the 4 TB Rocket 5 rarely encounters a scenario where write performance drops to problematic levels during consumer workloads. 4K random read performance at high queue depths outpaces any PCIe 4.0 drive, though at typical desktop queue depths of QD1 to QD4 the improvement over premium PCIe 4.0 drives like the Samsung 990 Pro is modest. Real-world file transfers between PCIe 5.0 drives can sustain peak write throughput for the duration of the transfer, making the 4 TB model well-suited for data-intensive professional environments.

## Endurance, TBW & Warranty

Sabrent covers the Rocket 5 4 TB with a five-year warranty and a 2,400 TBW endurance rating. This allows approximately 1,315 GB of writes per day for five consecutive years before hitting the endurance limit. For users writing 20 to 50 GB daily, the drive will last many times beyond the warranty period. The 2 million hour MTBF rating further underscores the drive's reliability engineering. Product registration is required for the full warranty term. The TBW threshold scales linearly with capacity across the Rocket 5 lineup. Buyers who do not register the product may receive a shorter warranty period, so completing registration through Sabrent's website is advisable.

## Pros and Cons

**Pros:**

- Up to 14,000 MB/s sequential read speed
- 2,400 TBW endurance rating at 4 TB
- Maximum NAND channel utilization
- Phison E26 controller with DDR4 DRAM
- Consistent sustained write performance
- Five-year warranty with registration
**Cons:**

- Requires PCIe 5.0 motherboard for full speed
- Higher power draw than smaller capacities
- Double-sided PCB may limit heatsink compatibility
- Premium pricing at the 4 TB capacity
- Runs hot under sustained writes


## Verdict

The Sabrent Rocket 5 4 TB is the highest-capacity PCIe 5.0 SSD in Sabrent's portfolio and one of the most capacious Gen5 drives available. Its combination of 14,000 MB/s reads, 2,400 TBW endurance, and full NAND channel utilization makes it ideal for users with large storage needs and PCIe 5.0-capable hardware.

Most buyers do not need PCIe 5.0 bandwidth at 4 TB. If your workflow does not involve frequent large file transfers, the Samsung 990 Pro 4 TB or WD Black SN850X 4 TB on PCIe 4.0 deliver comparable everyday performance at lower cost and power. The Rocket 5 4 TB is best suited for professionals working with 4K and 8K video, large datasets, or anyone who regularly moves tens or hundreds of gigabytes between fast drives.

## Frequently Asked Questions

### Is the Sabrent Rocket 5 4 TB compatible with PS5?

No. The PS5 requires PCIe 4.0 NVMe M.2 SSDs with at least 5,500 MB/s sequential read and a maximum size of 110 x 25 x 11.25 mm with heatsink. The Rocket 5 4 TB is a PCIe 5.0 desktop drive that exceeds the PS5's power and thermal limits. Additionally, the double-sided PCB may not fit the PS5's M.2 bay. Consider the Samsung 990 Pro 4 TB for PS5.

### Does the Sabrent Rocket 5 4 TB have double-sided NAND?

Yes, at 4 TB the Rocket 5 uses a double-sided PCB with NAND chips on both sides of the module. This can limit compatibility with some aftermarket heatsinks and low-profile M.2 slots. Check your motherboard and cooler clearances before purchasing. Most modern motherboards with PCIe 5.0 M.2 slots are designed to accommodate double-sided modules.

### What is the TBW endurance of the Sabrent Rocket 5 4 TB?

The 4 TB Rocket 5 has a 2,400 TBW endurance rating. This means you can write approximately 1,315 GB per day for five years before exceeding the rated endurance. For typical consumer workloads of 20 to 50 GB per day, the drive will far outlast its warranty period. The high endurance reflects the TLC NAND and generous over-provisioning at this capacity.

### How does the 4 TB Rocket 5 compare to the PNY XLR8 CS3250 4 TB?

The CS3250 uses the newer Phison E28 controller, which can reach higher sequential read speeds of up to 14,900 MB/s versus the Rocket 5's 14,000 MB/s. Both use Micron 232-layer TLC NAND and offer similar endurance. The CS3250 has a slight edge in peak throughput, while the Rocket 5 may be more widely available depending on your region.

### Does the Rocket 5 4 TB need active cooling?

A heatsink is mandatory for the 4 TB Rocket 5. PCIe 5.0 drives generate substantial heat, and the 4 TB model draws more power than the 1 TB and 2 TB variants. Most motherboards with PCIe 5.0 M.2 slots include a dedicated heatsink. If yours does not, install an aftermarket M.2 cooler rated for PCIe 5.0 thermal output.

### Can the Rocket 5 4 TB work in a PCIe 4.0 motherboard?

Yes, it is backward-compatible with PCIe 4.0 and 3.0. On a PCIe 4.0 x4 slot, sequential speeds are capped at roughly 7,400 MB/s. On PCIe 3.0 x4, the limit is approximately 3,900 MB/s. Full 14,000 MB/s read speed requires a PCIe 5.0 x4 M.2 slot. Power consumption also decreases on slower bus generations.
