# Transcend MTE240S 1TB — High-Endurance PCIe 4.0 NVMe SSD (2026)

The Transcend MTE240S 1TB stands out not for peak speed but for endurance — its 1,700 TBW rating is among the highest of any consumer PCIe 4.0 drive, making it a rare value pick for write-heavy workloads.

Quick answer: The Transcend MTE240S 1 TB is a niche drive that will be exactly right for a specific buyer and unremarkable for everyone else. If your workload involves heavy sustained writes — video editing scratch, surveillance recording, database operations, or any application that burns through consumer SSD endurance ratings — the 1,700 TBW rating and 5-year warranty make the MTE240S one of the best value propositions in the consumer PCIe 4.0 market. The peak throughput is modest at 3,800 MB/s reads, but write endurance is the bottleneck in these use cases, not sequential speed. Skip it if you are building a gaming PC or general-purpose desktop where 600 TBW is already overkill — the Samsung 980 or WD Blue SN570 will deliver faster reads and a more polished software ecosystem at a similar price. The MTE240S is a reliability-first product from a company with an industrial storage pedigree, and that focus shows in the spec sheet.

## Performance

Transcend rates the 1 TB MTE240S at up to 3,800 MB/s sequential reads and 3,200 MB/s sequential writes, with random performance rated at up to 370,000 IOPS read and 560,000 IOPS write. These figures place the MTE240S in an unusual position: it uses the PCIe 4.0 x4 interface but delivers throughput closer to a high-end PCIe 3.0 drive like the Samsung 970 EVO Plus (3,500 MB/s). The four-channel SM2267 controller is the bottleneck — it was designed as a cost-reduced PCIe 4.0 option for drives that prioritize endurance and value over peak bandwidth.

The DRAM-less HMB architecture adds minimal latency for consumer workloads. Game load times, application launches, and OS boot responsiveness are dominated by random read latency, where the MTE240S performs adequately if not exceptionally. The 3D TLC NAND provides predictable sustained write behavior, and the large overprovisioning implied by the 1,700 TBW endurance rating suggests Transcend has allocated generous spare area for the controller to manage wear leveling — a design choice that trades some usable capacity for long-term write consistency.

For its intended audience — users who value endurance over peak throughput — the MTE240S delivers exactly what the spec sheet promises. The 1,700 TBW rating is not a marketing exaggeration; it is a conservative, warranty-backed figure that reflects Transcend's industrial and embedded-storage heritage. Independent testing confirms the drive meets its rated speeds under sustained load without thermal throttling in adequately ventilated enclosures.

## Endurance, TBW & Warranty

Transcend backs the MTE240S 1 TB with a 5-year limited warranty capped at 1,700 TBW — whichever limit is reached first ends the coverage period. The 1,700 TBW figure is the standout specification: it is roughly two to three times the endurance rating of most consumer PCIe 4.0 TLC drives at this capacity, including the Samsung 980 (600 TBW) and WD Blue SN570 (600 TBW). At a typical consumer write load of 30 to 50 GB per day, the drive would last 93 to 155 years — effectively unlimited for consumer use. For write-intensive workloads like 4K video capture or database logging at 200 GB per day, the TBW ceiling would still take over 23 years to reach, meaning the 5-year warranty window is the binding constraint for most use cases. Transcend's RMA process is well established, with service centers in North America, Europe, and Asia. The drive does not require registration, but retaining proof of purchase is recommended for warranty claims.

## Pros and Cons

## Frequently Asked Questions

### Is the Transcend MTE240S 1TB good for gaming?

It is adequate but not the best choice for a pure gaming build. The 3,800 MB/s reads deliver game load times within a second of faster PCIe 4.0 drives, and the 1 TB capacity provides room for the OS and a moderate game library. However, gaming does not benefit from the MTE240S's headline feature — the 1,700 TBW endurance — because games write data infrequently after the initial install. For the same price, drives like the Samsung 980 or WD Blue SN570 offer faster reads (up to 3,500 MB/s on PCIe 3.0) and better software support. The MTE240S makes more sense as a secondary scratch disk for content creation or as a system drive in a workstation where endurance matters more than peak gaming throughput.

### Is the Transcend MTE240S compatible with the PS5?

The MTE240S 1 TB meets the form-factor and interface requirements for the PS5 expansion slot — it is a PCIe 4.0 x4 NVMe M.2 2280 drive with a single-sided PCB. However, the rated 3,800 MB/s sequential read speed falls well below Sony's 5,500 MB/s recommendation. While the drive will physically fit and the PS5 may recognize it, performance in PS5-native titles that leverage the console's fast storage API could be affected by the bandwidth shortfall. Sony does not list this drive on its compatibility page. Buyers who want guaranteed PS5 compatibility should choose a drive rated at 5,500 MB/s or higher, such as the WD Black SN770 or Samsung 980 PRO.

### Does the Transcend MTE240S have a DRAM cache?

No, the MTE240S uses a DRAM-less controller — identified in independent reviews as the Silicon Motion SM2267 — that relies on the Host Memory Buffer (HMB) feature of NVMe to allocate system RAM for the mapping table. Some retail listings describe this as a DRAM cache or SDRAM buffer, but these terms refer to the HMB allocation, not a physical DRAM chip on the SSD PCB. HMB is sufficient for mapping-table performance in consumer workloads, though it adds microseconds of latency versus a dedicated DRAM chip under heavy multitasking. Transcend does not officially disclose the controller model or DRAM configuration.

### What is the TBW endurance of the Transcend MTE240S 1TB?

The 1 TB MTE240S is rated for 1,700 TBW (Terabytes Written), which is among the highest endurance ratings of any consumer PCIe 4.0 NVMe SSD currently available. For comparison, the Samsung 980 1 TB is rated at 600 TBW, the WD Blue SN570 1 TB at 600 TBW, and even the premium Samsung 980 PRO 1 TB at 600 TBW. The MTE240S's 1,700 TBW is nearly triple those figures. At a typical daily write load of 30 GB, the drive would last over 150 years. At a heavy 200 GB per day — consistent with 4K video editing or database workloads — it would still last over 23 years before hitting the TBW ceiling. The 5-year warranty is tied to this TBW cap: whichever is reached first ends coverage.

### Does the Transcend MTE240S need a heatsink?

Transcend does not ship the MTE240S with a pre-installed heatsink, and for typical desktop use a dedicated heatsink is not required. The four-channel controller and modest power consumption generate less heat than eight-channel PCIe 4.0 flagships, and most desktop motherboards include an M.2 thermal solution that provides adequate cooling. For the PS5 expansion slot, Sony requires a heatsink, and since the MTE240S does not include one, buyers must add a third-party low-profile heatsink. In laptops, the existing airflow and thermal pad are generally sufficient for the MTE240S's thermal output under consumer workloads.

### How does the MTE240S compare to the Samsung 980?

The Samsung 980 (non-PRO) is a PCIe 3.0 drive rated at 3,500 MB/s reads and 3,000 MB/s writes, with 600 TBW endurance and a 5-year warranty for the 1 TB model. The MTE240S edges it on peak throughput (3,800 vs 3,500 MB/s reads) and dramatically exceeds it on endurance (1,700 vs 600 TBW), while the 980 benefits from Samsung's mature controller firmware, Magician software suite, and broader availability. For a general-purpose system drive, the 980 is the more polished product. For a write-intensive scratch disk, the MTE240S's endurance advantage is decisive. At similar pricing, the choice hinges on whether the workload justifies trading Samsung's ecosystem for Transcend's endurance headroom.

### Is the Transcend MTE240S available in 2TB?

No, Transcend offers the MTE240S in only two capacities: 500 GB and 1 TB. There is no 2 TB variant. The 500 GB model carries proportionally lower endurance — approximately 850 TBW — and the same 3,800 MB/s read and 3,200 MB/s write ratings. Buyers who need 2 TB or more should look at alternatives like the Samsung 980 PRO 2 TB, WD Black SN770 2 TB, or Transcend's own higher-end MTE250S series, which offers capacities up to 4 TB.
