Transcend 245S 4TB Gen4 x4 NVMe PCIe M.2 2280 Internal SSD

The Transcend 245S 4TB is a high-capacity internal solid-state drive designed for the M.2 2280 form factor, utilising the PCIe Gen4 x4 interface with NVMe protocol. The M.2 2280 footprint — 22 mm wide by 80 mm long — fits natively into desktop motherboards and laptops that expose a Gen4-capable M.2 slot, making it a practical upgrade path for users who need substantial local storage without occupying a drive bay. The drive employs 3D NAND flash memory, a stacked-cell architecture that delivers greater storage density within the same physical footprint compared to planar NAND. Stacking memory cells vertically allows the 245S to achieve 4 TB of usable capacity in a single M.2 module. Thermal management is handled by an integrated graphene heatsink combined with a dynamic thermal throttling mechanism. Graphene is a highly thermally conductive material; when bonded to the drive controller, it helps distribute and dissipate heat more effectively than a bare module. The dynamic throttling logic adjusts drive performance in response to temperature readings, prioritising stability during sustained workloads — a relevant consideration for a 4 TB drive that may be used in video editing, large file transfers, or backup operations. The PCIe Gen4 x4 interface doubles the available bandwidth of Gen3 x4, enabling the drive to serve demanding sequential read and write workloads. This interface requires a host system with a PCIe Gen4-compatible M.2 slot; the drive will operate in Gen3 x4 mode on older platforms with reduced peak throughput.
