# MSI Spatium M370 2TB Review: Gen3 Bulk Storage, Long Warranty (2026)

The MSI Spatium M370 2TB stretches a modest Gen3 platform across 2TB with 1,600 TBW of endurance and the family's fastest write rating at 1,850 MB/s.

Quick answer: Buy the MSI Spatium M370 2TB as TLC bulk storage with an unusually long warranty for the tier — game libraries, media archives and backup staging on a Gen3-era board are exactly its job, and 1,600 TBW of endurance backs the duty. Skip it when speed per dollar matters: the Gen4 WD Blue SN580 2TB outrates it substantially for similar money on modern boards, and no amount of capacity fixes its PS5 incompatibility on PCIe 3.0. The Crucial P3 2TB is the cheaper QLC alternative, with weaker post-cache writes as the trade. Within the M370 line, this is the capacity where the platform's endurance and write ratings peak. Endurance per terabyte is the strongest argument it makes.

## Performance

MSI rates the 2TB Spatium M370 at 2,400 MB/s sequential reads and 1,850 MB/s writes — the family's fastest write rating — with 220K random-read and 330K random-write IOPS. TechPowerUp's entry for this exact capacity confirms both figures. The platform's sustained-write character carries over from TechPowerUp's 1TB testing, which measured a dynamic pseudo-SLC cache of roughly 23 GB before writes settled near 500 MB/s; the 2TB model's cache is larger and unpublished, but the same pattern applies — quick bursts, then a several-hundred-MB/s floor on long transfers.

For bulk-storage duty, that trade is acceptable but worth understanding. Filling the drive with a game library happens mostly across the cache in hundreds of smaller writes, and 1,850 MB/s moves a 100 GB title in about a minute while it lasts. Sustained multi-hundred-gigabyte transfers — full backups, video archives — drop to the post-cache floor for their second half. Reads are unaffected: 2,400 MB/s loads games within a second of Gen4 drives, and 220K random-read IOPS keeps a packed library browsing smoothly. As a secondary drive on a Gen3 system, the numbers line up with the job; as a scratch disk, look elsewhere.

## Endurance, TBW & Warranty

MSI covers the Spatium M370 2TB for five years or 1,600 TBW, whichever arrives first — the largest endurance budget in the family and a 0.44 drive-writes-per-day class across the term. In everyday terms, a steady 20 GB of daily writes would take more than two centuries to exhaust the budget, so the warranty term is the practical limit even for a drive filling and rewriting large media collections. The ladder gives the 1TB half this budget at 800 TBW and the 256GB an eighth at 200 TBW. MTBF is rated up to 1.5 million hours, a fleet statistic rather than a single-drive promise. LDPC error correction, end-to-end data path protection and TCG Pyrite encryption run underneath, and claims go through MSI's standard support channels with proof of purchase.

## Pros and Cons

**Pros:**

- 1,600 TBW endurance with 5-year warranty
- Rated 2,400/1,850 MB/s on PCIe 3.0
- Fastest write rating in the M370 family
- Kioxia BiCS4 TLC, not QLC
- 220K random-read IOPS rating
- 2.15 mm height for thin slots
**Cons:**

- Trails Gen4 value drives' 5,000 MB/s reads
- No PS5 compatibility on PCIe 3.0
- DRAM-less, Host Memory Buffer only
- Post-cache writes settle near 500 MB/s
- Rated slower than the Crucial P3's 3,500 MB/s reads


## Verdict

Buy the MSI Spatium M370 2TB as TLC bulk storage with an unusually long warranty for the tier — game libraries, media archives and backup staging on a Gen3-era board are exactly its job, and 1,600 TBW of endurance backs the duty. Skip it when speed per dollar matters: the Gen4 WD Blue SN580 2TB outrates it substantially for similar money on modern boards, and no amount of capacity fixes its PS5 incompatibility on PCIe 3.0. The Crucial P3 2TB is the cheaper QLC alternative, with weaker post-cache writes as the trade. Within the M370 line, this is the capacity where the platform's endurance and write ratings peak. Endurance per terabyte is the strongest argument it makes.

## Frequently Asked Questions

### Is the MSI Spatium M370 2TB compatible with the PS5?

No. Sony's published requirements call for a PCIe 4.0 NVMe drive with a 5,500 MB/s or faster recommended read speed and a heatsink within its size envelope. The M370 2TB is a PCIe 3.0 drive rated at 2,400 MB/s with no heatsink, so it fails on interface generation, speed and cooling simultaneously — capacity is the only criterion it clears. TechPowerUp's database marks the platform not PS5-compatible. A console upgrade needs a Gen4 drive with a fitted cooler, regardless of how attractive this drive's price looks.

### Is the MSI Spatium M370 2TB good for gaming?

As a PC game-library drive, yes — with the right expectations. Reads at 2,400 MB/s load games within about a second of Gen4 drives, 220K random-read IOPS keeps a packed library browsing smoothly, and 2TB holds a large permanent collection without uninstall churn. The caveats: 1,850 MB/s burst writes slow the biggest installs once the SLC cache fills, and DirectStorage-heavy titles will be limited by PCIe 3.0 itself. On an older Gen3 board it is a coherent library drive; on a new Gen4 system, a Gen4 drive is the better spend.

### What is the TBW endurance of the MSI Spatium M370 2TB?

The 2TB model is rated at 1,600 TBW under a five-year limited warranty, whichever comes first — the largest budget in the M370 family, which runs 75, 200, 400, 800 and 1,600 TBW across its capacities. MSI's product page cites the 1,600 TBW figure directly. In everyday terms, a steady 20 GB of daily writes would take more than two centuries to exhaust it, so even a media-archival workload never approaches the cap. TLC NAND rather than QLC is what makes this endurance class credible at the price tier.

### Does the MSI Spatium M370 have a DRAM cache?

No — every M370 capacity, including this 2TB, is DRAM-less. Phison's E13T controller uses Host Memory Buffer to borrow system RAM for the flash translation table, plus a dynamic pseudo-SLC cache carved from the NAND for burst writes; TechPowerUp's teardown of the platform confirms the design and identified the controller as the PS5015-E15. In desktop and library duty the practical penalty is small. Sustained heavy writing is where it shows: TechPowerUp measured the 1TB sibling settling near 500 MB/s after roughly 23 GB of cache, and the 2TB follows the same pattern with a larger cache.

### How does the MSI Spatium M370 2TB compare to the Crucial P3 2TB?

Both are DRAM-less PCIe 3.0 drives aimed at the value tier, and the NAND is the whole argument. The P3 uses QLC: it rates 3,500 MB/s reads against the M370's 2,400, but QLC's post-cache write speeds collapse far lower than this drive's roughly 500 MB/s floor, and QLC endurance is structurally weaker — the P3 2TB carries a 1,200 TBW rating against 1,600 here. The M370 counters with TLC consistency and a matching five-year warranty. Choose the P3 for the lowest price per gigabyte on mostly-read duty; choose the M370 when writes and longevity matter.

### Why does the 2TB M370 write faster than the 1TB?

NAND parallelism. The 2TB model carries twice the flash packages of the 1TB, letting the E13T controller interleave writes across more dies at once — MSI rates it at 1,850 MB/s against the 1TB's 1,750, and random reads rise from 215K to 220K IOPS. Reads change little because they depend less on die interleaving, while write throughput scales with the number of packages available. Endurance doubles in step, from 800 to 1,600 TBW. It is the standard capacity-ladder pattern: the largest capacity of a given controller almost always posts the best ratings.

### Is the MSI Spatium M370 2TB a good drive for video storage?

For storing and browsing footage, yes; for active editing work, only partly. Reading large video files back is a strength — 2,400 MB/s sequential reads cover multiple 4K streams comfortably, and the 2TB pool holds hours of footage. The weakness is ingest and export: once the SLC cache fills during a sustained transfer, writes settle near 500 MB/s, which slows multi-hundred-gigabyte card dumps and renders. Working editors should treat it as an archive drive behind a faster scratch disk; hoarders and backup planners will find the 1,600 TBW endurance and five-year warranty well matched.
