MSI Spatium M480 Pro 4TB Review — Maximum Gen4 Capacity (2026)
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.
Read: 7400 MB/s Write: 7000 MB/s Endurance: 3000 TBW Warranty: 5 years Interface: M.2 4.0 x 4
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.
Controller & Memory
The MSI Spatium M480 Pro 4TB is the top of MSI's Phison-based flagship line, and at this capacity nothing is held back: the eight-channel PS5018-E18 controller works over PCIe 4.0 x4 with Micron 176-layer 3D TLC NAND, 2 GB of DDR4 DRAM and AES-256 hardware encryption on a standard M.2 2280 board. The rating is the family's full specification — 7,400 MB/s sequential reads, 7,000 MB/s sequential writes and 1 million IOPS in both random directions — and endurance peaks at 3,000 TBW under a 5-year warranty. A graphene pad cools the bare drive, with a heatsink-equipped variant in the lineup.
The capacity ladder matters here. The 1 TB model trims writes to 6,000 MB/s and endurance to 700 TBW, the 2 TB restores the full rating at 1,400 TBW, and the 4 TB doubles the endurance budget again to 3,000 TBW — the largest flash-wear allowance in the family. For a drive meant to hold entire game collections and multi-terabyte project archives, that headroom is the point of stepping up.
Buyers at 4 TB are choosing between DRAM-equipped flagships and the cheaper DRAM-less tier. Samsung's 990 Pro 4TB and WD's Black SN850X 4TB are the like-for-like rivals, both excellent and usually priced accordingly; Lexar's NM790 4TB and Crucial's P3 Plus 4TB represent the DRAM-less value route, trading cache consistency and, in Crucial's case, TLC NAND for a lower bill. The M480 Pro 4TB's case rests on the E18 platform's long track record — TechPowerUp's and wccftech's reviews of the 2 TB sibling put it at the front of the Gen4 pack — combined with the family's highest endurance rating.

Spatium M480 Pro Performance & Benchmarks
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.

- Patriot Viper PV593 1 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 2 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
- MSI Spatium M480 Pro 4 TB (this drive): 7,400 MB/s read, 7,000 MB/s write
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.

Verdict: Is the Spatium M480 Pro Worth It in 2026?
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.
