# Transcend MTE250H 4TB Review: Big Gen4 Storage, Fins Attached (2026)

The Transcend MTE250H 4TB tops its family with 7,500 MB/s reads, 6,700 MB/s writes and a 3,120 TBW endurance budget, cooler already fitted.

Quick answer: Buy the Transcend MTE250H 4TB for PS5 expansion or a large game and video library where a fitted heatsink and a 3,120 TBW endurance budget matter more than absolute peak speed. Skip it if price per gigabyte drives the decision — Crucial's QLC-based P3 Plus 4TB undercuts it, with a steep post-cache write penalty as the cost — or if rated speed leads, where Samsung's 990 Pro 4TB and WD's SN850X 4TB both outrate it. Tom's Hardware found the family pricey in the US, so the value case rests on the warranty, thermals and convenience. As a set-and-forget 4TB Gen4 drive with cooling solved at the factory, it makes a coherent package.

## Performance

Transcend rates the 4TB MTE250H at 7,500 MB/s sequential reads, 6,700 MB/s writes and 540K/440K random read/write IOPS — the strongest figures in the family, and ratings that clear Sony's 5,500 MB/s PS5 guidance with room to spare. TechPowerUp measured the 1TB sibling's dynamic pseudo-SLC cache at roughly 100 GB before writes fell to about 788 MB/s; the cache scales with capacity on this platform, so the 4TB model holds cache-protected writes for longer stretches before settling to its steady-state floor.

For the target workloads, character matters more than peak burst. A 4TB pool absorbs huge game installs and shader caches; sustained transfers — moving a Steam library, offloading an SD card of 4K footage — run at multi-GB/s rates while the cache lasts and remain far above SATA speeds after it. Tom's Hardware's family testing highlighted how effectively the factory fins hold thermals, which is what keeps those sustained rates from throttling on a long copy. Random-write ratings trail DRAM-based flagships like Kingston's KC3000, but queue-depth-1 responsiveness — what boots, clicks and level loads actually feel like — is governed by latency, and the DRAM cache keeps that consistent.

## Endurance, TBW & Warranty

The 4TB MTE250H carries the family's largest endurance budget: 3,120 TBW under a five-year limited warranty, whichever arrives first, equal to 0.43 drive writes per day across the term. In everyday terms, a steady 20 GB of daily writes would take more than four centuries to exhaust, so the warranty clock is the only realistic limit. The ladder below is 780 TBW on the 1TB and 1,560 on the 2TB at the same daily-write class — the 4TB simply multiplies the budget. MTBF is rated at 3.0 million hours, a fleet-level statistic rather than a promise for any single unit. Transcend's documentation warns that removing the factory-fitted heatsink can cause damage not covered under warranty, so the drive should be installed as-is, and the bundled SSD Scope utility tracks health and remaining life.

## Pros and Cons

**Pros:**

- Rated 7,500/6,700 MB/s — family's fastest
- 3,120 TBW endurance, five-year warranty
- Pre-fitted aluminum heatsink, PS5-eligible size
- 540K/440K random IOPS rating
- DRAM cache platform with NVMe 1.4
- Fits Sony's 11.25 mm PS5 envelope
**Cons:**

- 990 Pro and SN850X 4TB rate faster
- Priced high in the US, per Tom's Hardware
- Post-cache write floor untested at 4TB
- 9.2 mm height fouls some laptop M.2 slots
- Heatsink removal risks warranty, per Transcend


## Verdict

Buy the Transcend MTE250H 4TB for PS5 expansion or a large game and video library where a fitted heatsink and a 3,120 TBW endurance budget matter more than absolute peak speed. Skip it if price per gigabyte drives the decision — Crucial's QLC-based P3 Plus 4TB undercuts it, with a steep post-cache write penalty as the cost — or if rated speed leads, where Samsung's 990 Pro 4TB and WD's SN850X 4TB both outrate it. Tom's Hardware found the family pricey in the US, so the value case rests on the warranty, thermals and convenience. As a set-and-forget 4TB Gen4 drive with cooling solved at the factory, it makes a coherent package.

## Frequently Asked Questions

### Is the Transcend MTE250H 4TB compatible with the PS5?

Yes — this is the family capacity built for it. The drive satisfies every published Sony requirement: PCIe 4.0 NVMe, a 7,500 MB/s read rating comfortably above the 5,500 MB/s recommendation, and 80 x 23.1 x 9.2 mm dimensions with the factory heatsink, inside the 110 x 25 x 11.25 mm limit. Sony does not list the 250H on its tested-and-recommended page, but TechPowerUp's database marks the platform PS5-compatible. With 4TB on board, a console library of large current-generation games fits without constant pruning.

### Is the Transcend MTE250H 4TB good for gaming?

For gaming it is arguably the most sensible capacity in the 250H family. Reads at 7,500 MB/s load levels indistinguishably from faster-rated flagships, 4TB holds a large permanent library on either a PC or a PS5, and 6,700 MB/s writes make 100 GB-plus installs quick. Endurance of 3,120 TBW absorbs years of installing, deleting and re-downloading. The 440K random-write rating trails flagship controllers, but game loading is dominated by read patterns and queue-depth-1 latency, where the DRAM cache keeps responses consistent.

### What is the TBW endurance of the Transcend MTE250H 4TB?

The 4TB model is rated at 3,120 TBW under a five-year limited warranty, whichever comes first — the largest budget in the family, which assigns 780 TBW to the 1TB and 1,560 TBW to the 2TB at the same 0.43 drive-writes-per-day class. A steady 20 GB of daily writes would need more than four centuries to exhaust the budget, so the warranty term is the practical limit for any consumer workload. The figure comes from Transcend's official per-capacity table and doubles with each step up the ladder.

### Is a 4TB SSD overkill for a boot drive?

As a pure boot drive, yes — an operating system and office workload would use a sliver of the space and almost none of the 3,120 TBW endurance budget. The 4TB MTE250H is designed for secondary duty: a Steam or PS5 library, 4K video projects, photo archives or a virtual machine collection. That said, a single large drive can split roles — partitions for system and data work fine, and the DRAM cache keeps boot performance identical to the smaller capacities. Buy 4TB for what will live on it, not for the boot partition alone.

### Does the Transcend MTE250H 4TB need an extra heatsink?

No — the finned aluminum heatsink is factory-fitted, which is the defining feature of the H variant. Transcend claims the aluminum design cuts drive temperatures by about 15 percent compared with a bare drive, and Tom's Hardware's testing credited the cooler's thermal control. The company also warns that removing the heatsink can cause damage not covered under warranty, so install the drive as-is. The only restriction is height: at 9.2 mm it can foul laptop M.2 slots and some tight small-form-factor cases, where the 3.77 mm graphene-padded MTE250S is the alternative.

### How does the Transcend MTE250H 4TB compare to the WD Black SN850X 4TB?

The SN850X outrates it on paper — roughly 7,300/6,600 MB/s with a stronger random profile and a well-documented sustained-write record — and it is the safer pick for speed-first buyers. The MTE250H counters with the heatsink included at no extra fuss, a five-year warranty with 3,120 TBW of endurance, and Transcend's SSD Scope utility for monitoring. Real-world game loading between the two is effectively indistinguishable. Choose the SN850X for peak performance and pedigree; choose the Transcend when a fitted cooler, the endurance budget and a simpler purchase matter.

### Why does the 4TB MTE250H write faster than the smaller capacities?

NAND parallelism. The 4TB model carries twice the flash packages of the 2TB and four times the 1TB, so the SM2264F controller can interleave writes across more dies simultaneously — that is why rated writes climb from 6,200 MB/s on the 1TB to 6,500 on the 2TB and 6,700 here, while reads rise to 7,500 MB/s. Endurance scales the same way, from 780 to 1,560 to 3,120 TBW. Larger capacities of a given controller almost always post the best numbers, which is why flagship reviews rarely reflect what the 1TB box delivers.
