Couldn't load pickup availability
The Transcend PCIe SSD 255S is a high-performance M.2 NVMe solid-state drive designed for demanding computing environments, including gaming, advanced video editing, software development, and professional workloads. Featuring a PCIe Gen4 x4 interface, NVMe 1.4, 3D NAND flash, and a multi-channel controller, it delivers sequential read speeds of up to 7,400MB/s.
Available in 1TB and 2TB capacities, the SSD 255S combines high-speed storage with a compact single-sided M.2 2280 design. An integrated graphene heatsink assists with heat dissipation, while LDPC error correction and dynamic thermal throttling help maintain stable performance during demanding workloads.
Key Features
PCIe Gen4 x4 NVMe Performance
The SSD 255S supports the NVMe 1.4 standard and uses a PCIe Gen4 x4 bus interface, providing significantly higher bandwidth than traditional SATA-based SSDs.
High-Speed Sequential Performance
The drive delivers sequential read speeds of up to 7,400MB/s and sequential write speeds of up to 6,500MB/s, depending on capacity.
High Random IOPS
With up to 700,000 random read IOPS and 500,000 random write IOPS, the SSD is designed to provide responsive performance for demanding applications and multitasking.
PCIe 4.0 with Backward Compatibility
PCIe Gen4 provides increased transfer bandwidth and lower system latency. The SSD 255S is also backward compatible with PCIe 3.0, although performance depends on the host system.
Integrated Graphene Heatsink
An ultra-thin graphene heatsink helps improve heat dissipation. The high thermal conductivity of graphene assists in maintaining stable device performance.
Single-Sided M.2 2280 Design
The compact M.2 2280 single-sided form factor is suitable for compatible desktops, laptops, and ultrabooks.
Up to 2TB Capacity
The SSD 255S is available in 1TB and 2TB capacities, providing substantial storage for games, applications, video projects, software development files, and other large datasets.
LDPC Error Correction
LDPC (Low-Density Parity Check) coding provides ECC-based error correction to help maintain data integrity and reliable operation.
Dynamic Thermal Throttling
Dynamic thermal throttling helps manage operating temperatures during sustained workloads, supporting stability and endurance.
SSD Scope Software
Transcend SSD Scope provides tools for monitoring SSD health and optimizing drive performance.

Storage & Endurance
The SSD 255S provides endurance ratings of:
- 1TB: 600TBW
- 2TB: 1,200TBW
The drive is rated at 0.33 DWPD over 5 years.
Cooling & Thermal Management
The integrated graphene heatsink is designed to improve heat dissipation while maintaining the slim M.2 form factor. Dynamic thermal throttling helps manage temperature during sustained workloads.
Reliability & Data Integrity
The SSD 255S incorporates LDPC coding, an ECC algorithm designed to detect and correct errors. Transcend also conducts testing for vibration, temperature, humidity, speed, and functionality during production.
Compatibility
The SSD 255S requires a compatible M.2 slot supporting NVMe PCIe connectivity.
Supported operating systems include:
- Microsoft Windows 7 or later
- Linux Kernel 2.6.31 or later
The drive supports PCIe Gen4 x4 and is backward compatible with PCIe 3.0.
Some motherboards may provide only PCIe x2 connectivity through an M.2 slot, which can limit the performance of the SSD.
