# MSI Spatium M370 1TB Review: A Mid-2021 Gen3 Value Play (2026)

Launched in mid-2021, the MSI Spatium M370 1TB remains a plain-spoken Gen3 drive — 2,400 MB/s reads, 800 TBW endurance and a five-year warranty.

Quick answer: Buy the MSI Spatium M370 1TB when the price sits clearly below faster-rated Gen3 rivals and a five-year warranty matters more than headline speed — it is a safe, TLC-based system drive for older Gen3 desktops and laptops. Skip it on any Gen4 or Gen5 board, where value drives like the WD Blue SN570 or Samsung 980 out-rate it at similar money, and rule it out for PS5 storage entirely. The Crucial P3 undercuts it with QLC and weaker sustained writes; the SN570 is the stronger all-rounder. Judged as a 2021 design still sold into the budget tier, the M370 1TB is coherent but never quick. At this capacity it is also the most practical pick in the family.

## Performance

MSI rates the 1TB Spatium M370 at 2,400 MB/s sequential reads and 1,750 MB/s writes on PCIe 3.0 x4, with 215K random-read and 330K random-write IOPS. TechPowerUp's testing of this exact capacity sized the dynamic pseudo-SLC cache at roughly 23 GB — modest even for the class — after which writes settle near 500 MB/s. That post-cache floor is the platform's defining weakness: a 100 GB game install or a large video export crosses the cache boundary quickly, and the second half of the transfer runs at a fraction of the rated speed.

Below the cache, behavior is more forgiving. Queue-depth-1 random reads and latency — what boot times and app launches actually feel — stay competitive for a DRAM-less design thanks to Host Memory Buffer, and the 330K random-write rating keeps mixed desktop workloads responsive. Game loading differs from Gen4 drives by a second or two at most, since titles lean on small reads rather than sequential bursts. The M370 makes sense as a daily-use system drive where bursts stay small; where large sustained writes are routine, its 2021-era cache design shows its age against the WD Blue SN570 or Samsung 980.

## Endurance, TBW & Warranty

MSI covers the Spatium M370 1TB for five years or 800 TBW, whichever arrives first — a 0.4 drive-writes-per-day class that TechPowerUp notes is comparatively generous for a value drive. In daily terms, a steady 20 GB of writes per day would take more than a century to exhaust the budget, so the warranty term is the practical limit for virtually any desktop workload. The ladder puts this capacity at four times the 256GB model's endurance and half the 2TB's. MTBF is rated up to 1.5 million hours, a fleet statistic rather than a per-unit prediction. 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:**

- Rated 2,400 MB/s reads on PCIe 3.0 x4
- 800 TBW endurance with 5-year warranty
- Kioxia BiCS4 96-layer TLC, not QLC
- 330K random-write IOPS rating
- TCG Pyrite encryption support
- 2.15 mm height fits thin laptops
**Cons:**

- Trails 2021 Gen3 rivals' 3,000 MB/s write ratings
- 23 GB cache empties fast, writes fall to ~500 MB/s
- DRAM-less, Host Memory Buffer only
- No PS5 compatibility on PCIe 3.0
- Rated slower than the Crucial P3's 3,500 MB/s reads


## Verdict

Buy the MSI Spatium M370 1TB when the price sits clearly below faster-rated Gen3 rivals and a five-year warranty matters more than headline speed — it is a safe, TLC-based system drive for older Gen3 desktops and laptops. Skip it on any Gen4 or Gen5 board, where value drives like the WD Blue SN570 or Samsung 980 out-rate it at similar money, and rule it out for PS5 storage entirely. The Crucial P3 undercuts it with QLC and weaker sustained writes; the SN570 is the stronger all-rounder. Judged as a 2021 design still sold into the budget tier, the M370 1TB is coherent but never quick. At this capacity it is also the most practical pick in the family.

## Frequently Asked Questions

### Is the MSI Spatium M370 1TB compatible with the PS5?

No. Sony's published requirements call for a PCIe 4.0 NVMe drive with 5,500 MB/s or faster recommended read speed, a heatsink, and dimensions within 110 x 25 x 11.25 mm. The M370 is a PCIe 3.0 drive rated at 2,400 MB/s with no heatsink, so it fails on interface generation, speed and cooling at once. TechPowerUp's database explicitly marks it not PS5-compatible. A PS5 expansion needs a Gen4 drive with a fitted cooler; this drive belongs in PCs only.

### Is the MSI Spatium M370 1TB good for gaming?

For PC gaming on a Gen3-era system, adequately. Game loading is dominated by small random reads and queue-depth-1 latency, where the M370 performs close to faster-rated drives, so titles load within a second or two of Gen4 hardware. The 1TB capacity holds an operating system plus a real game library, and 330K random-write IOPS keeps things responsive while games, launchers and background apps share the drive. The limits appear in DirectStorage-heavy titles and huge installs, where the 2,400 MB/s ceiling and the small 23 GB SLC cache show their 2021 vintage.

### What is the TBW endurance of the MSI Spatium M370 1TB?

MSI rates the 1TB model at 800 TBW under a five-year limited warranty, whichever comes first — the same 0.4 drive-writes-per-day class MSI applies across the M370 ladder, which runs 75, 200, 400, 800 and 1,600 TBW from 128GB to 2TB. TechPowerUp's entry confirms the 800 TBW figure. In everyday terms, a steady 20 GB of daily writes would take more than a century to exhaust the budget, so flash wear is never the practical limit for a desktop workload; the warranty term is.

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

No. The entire M370 family 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 confirms the HMB design and measured the 1TB's cache at roughly 23 GB. In daily desktop use the difference from DRAM-equipped drives is small — latency at queue depth 1 stays competitive. The gap opens under sustained writing, where throughput drops to around 500 MB/s once the cache fills.

### How does the MSI Spatium M370 1TB compare to the Samsung 980 1TB?

The Samsung 980 is the stronger drive on every performance axis: 3,500/3,000 MB/s rated speeds against 2,400/1,750, a larger dynamic cache and Samsung's TurboWrite polish, all in the same DRAM-less, TLC, five-year-warranty format. The M370's counterarguments are price and endurance — its 800 TBW rating is solid for the tier, and street pricing often undercuts Samsung's. If the two cost about the same, the 980 is the straightforward pick; the M370 makes sense only when the discount is real and the workload never leans on sustained writes.

### Why do sources list the 1TB write speed as both 1,750 and 1,850 MB/s?

MSI's current official specification table rates the 1TB M370 at 2,400/1,750 MB/s, while TechPowerUp's database entry — based on an earlier datasheet revision — lists 1,850 MB/s. MSI's own marketing copy quotes 2,400/1,850, which appears to inherit the 2TB model's write figure. The discrepancy is a documentation drift, not different hardware: the capacities share one platform. This article follows MSI's current per-capacity table at 1,750 MB/s; either way, real-world behavior is governed by the SLC cache, not the burst rating.

### Is a 2021-era Gen3 SSD still worth buying?

For the right system, yes. PCIe 3.0 drives remain fully compatible with modern Gen4 and Gen5 motherboards, running at Gen3 speeds, and everyday computing — boot times, office work, even game loading — extracts only a fraction of what any NVMe drive offers. The M370 1TB's five-year warranty, TLC NAND and 800 TBW endurance make it a low-risk purchase for older desktops and laptops. What has moved on is the price-performance frontier: Gen4 value drives now sell near Gen3 prices, so the M370 only makes sense when it is clearly cheaper than those alternatives.
