# MSI Spatium M480 Pro 4TB Review — Maximum Gen4 Capacity (2026)

The MSI Spatium M480 Pro 4TB caps MSI's E18 flagship line with 7,400 MB/s reads, 3,000 TBW of endurance and enough room for a full generation of game libraries.

Quick answer: The MSI Spatium M480 Pro 4TB makes sense for two buyers: the gamer consolidating an entire library onto one DRAM-equipped Gen4 drive, and the creator who wants PCIe 4.0 speed with the family's best endurance rating of 3,000 TBW on the proven E18 platform. Skip it when the platform speaks PCIe 5.0 and the budget stretches that far, or when the Crucial P3 Plus 4TB covers bulk-storage duty at a much lower cost. Between the like-for-like rivals, the Samsung 990 Pro 4TB carries the stronger brand and software story and the WD Black SN850X the deeper review history; this MSI wins whenever its price undercuts both of them at retail.

## Performance

MSI rates the 4 TB Spatium M480 Pro at 7,400 MB/s sequential reads, 7,000 MB/s sequential writes, and 1 million IOPS for both random reads and writes — identical to the 2 TB model and the full specification of Phison's E18 platform. No dedicated 4 TB benchmark suite has been published, but the platform's behavior is well documented from the 2 TB reviews: TechPowerUp measured burst writes starting near 5 GB/s through a roughly 192 GB pseudo-SLC cache, with strong sustained performance highlighted in its conclusions, and wccftech described the drive as maxing out the controller.

At 4 TB the pseudo-SLC cache scales with the NAND pool, so sustained-write headroom should be at least as generous as the tested 2 TB model's — treat that as reasoned expectation rather than a measured result. The use cases that matter at this capacity are bulk ones: game libraries measured in terabytes, 4K video projects, and DirectStorage-ready installs. Sequential throughput of this class makes SATA drives look ancient, and the 1M random-write rating keeps multi-terabyte folders responsive during reorganization. Cooling remains the one hardware requirement: the bare board runs warm under sustained load, so a motherboard heatsink or MSI's heatsink SKU is the sensible configuration.

## Endurance, TBW & Warranty

MSI covers the Spatium M480 Pro 4TB with a 5-year limited warranty rated to 3,000 TBW of host writes, whichever arrives first. That endurance budget is the largest in the Spatium line — triple the 1 TB model's 700 TBW and more than double the 2 TB's 1,400 TBW — and it works out to over 1.6 TB of writes per day across the warranty term. At a heavy 100 GB per day, the rating still stretches past eight decades, so the 5-year clock is the practical limit. MTBF is rated up to 1.6 million hours, a fleet-level statistic rather than a single-drive lifespan promise. AES-256 hardware encryption, end-to-end data path protection and LDPC error correction are all part of the platform, and claims go through MSI's support channels with proof of purchase.

## Pros and Cons

**Pros:**

- Full 7,400/7,000 MB/s rating at 4 TB
- 3,000 TBW endurance, the line's highest
- 2 GB DDR4 DRAM cache buffer
- 1M random-read and random-write IOPS ratings
- Micron 176-layer TLC NAND
- Heatsink variant available
**Cons:**

- No dedicated 4 TB independent benchmarks yet
- Bare drive runs warm without airflow
- Costs more than DRAM-less 4 TB alternatives
- Slower to find at retail than 1 TB and 2 TB models


## Verdict

The MSI Spatium M480 Pro 4TB makes sense for two buyers: the gamer consolidating an entire library onto one DRAM-equipped Gen4 drive, and the creator who wants PCIe 4.0 speed with the family's best endurance rating of 3,000 TBW on the proven E18 platform. Skip it when the platform speaks PCIe 5.0 and the budget stretches that far, or when the Crucial P3 Plus 4TB covers bulk-storage duty at a much lower cost. Between the like-for-like rivals, the Samsung 990 Pro 4TB carries the stronger brand and software story and the WD Black SN850X the deeper review history; this MSI wins whenever its price undercuts both of them at retail.

## Frequently Asked Questions

### Is the MSI Spatium M480 Pro 4TB compatible with the PS5?

It satisfies Sony's published requirements: a PCIe 4.0 NVMe drive, a recommended read speed of 5,500 MB/s or faster (this drive rates 7,400 MB/s), and dimensions under 110 x 25 x 11.25 mm including the heatsink. The bare board measures 80 x 22 x 2.15 mm, so a slim aftermarket heatsink keeps the assembly within Sony's thickness limit. Four terabytes is ample console storage for a large library, and the drive's 3,000 TBW endurance rating is far more than console use will consume. MSI's own PS5-positioned sibling is the Spatium M480 Play; the Pro needs an added heatsink but meets the same criteria.

### Is the MSI Spatium M480 Pro 4TB good for gaming?

Yes — a 4 TB Gen4 drive is the consolidator's choice, holding an operating system and dozens of 100 GB-plus installs on one stick. Rated reads of 7,400 MB/s sit at the top of the PCIe 4.0 class, load times match any other flagship Gen4 SSD, and the hardware DRAM cache keeps random access consistent even when the drive is mostly full. The only planning item is cooling: give it a motherboard heatsink or buy MSI's heatsink variant, since bare E18 boards run warm under sustained installs.

### What is the TBW endurance of the M480 Pro 4TB?

MSI rates the 4 TB model at 3,000 TBW of host writes under a 5-year limited warranty, whichever comes first. That is the highest endurance rating in the Spatium M480 Pro family — the 1 TB carries 700 TBW and the 2 TB carries 1,400 TBW. Three thousand terabytes equates to more than 1.6 TB of writes per day for the whole warranty period, a figure no consumer workload approaches, so the 5-year term will almost certainly end the coverage before the flash does. Independent coverage of the family confirms the 3,000 TBW figure for this capacity.

### Does the MSI Spatium M480 Pro 4TB have a DRAM cache?

Yes — the 4 TB model carries 2 GB of onboard DDR4 DRAM, the same amount as the 2 TB version and double the 1 TB model's 1 GB. The DRAM holds the flash translation table, which matters more as capacity grows: keeping a 4 TB drive's mapping data in onboard memory preserves random performance when the drive is near full, something DRAM-less designs approximate with the Host Memory Buffer. A pseudo-SLC cache carved from the TLC NAND handles burst writes on top.

### How does the MSI Spatium M480 Pro 4TB compare to the Samsung 990 Pro 4TB?

Both are DRAM-equipped PCIe 4.0 flagships with near-identical real-world speed; rated sequential numbers differ by a rounding error and load times will not separate them. The M480 Pro's 3,000 TBW rating exceeds the 990 Pro 4TB's 2,400 TBW, both under 5-year warranties. Samsung counters with a more mature software suite, deeper availability and the strongest brand track record in the category. The MSI's case is the higher endurance rating and the E18 platform's long review history — pick it when it costs less, and the Samsung when ecosystem support leads the decision.

### Is the 4TB M480 Pro faster than the 1TB model?

At the top end, yes. The 4 TB carries the family's full rating of 7,400 MB/s reads and 7,000 MB/s writes with 1 million IOPS in both random directions, while the 1 TB model trims writes to 6,000 MB/s and random reads to 750K IOPS. Its pseudo-SLC cache also spans a larger NAND pool, so it sustains burst writes longer. For boot-and-games duty the difference is imperceptible; for multi-hundred-gigabyte transfers and heavily populated drives, the 4 TB configuration is measurably the stronger one.
