Astounding Performance
Transcend’s PCIe SSD 115S follows NVMe 1.4 specifications and comes with the PCIe Gen3 x4 interface, meaning four lanes are used for transmitting and receiving data simultaneously, resulting in excellent performance of read speeds up to 3,200MB/s and write speeds up to 2,000MB/s.

Low Power Consumption
The PCIe SSD 115S comes in the M.2 2280 form factor, perfect for desktops, laptops, and ultrabooks! The low-power design makes PCIe performance possible with the best power efficiency.

Always Reliable, Always Evolving.
Transcend’s PCIe SSD 115S is engineered with LDPC (Low-Density Parity Check) coding, a powerful ECC algorithm, to keep data secure. Designed with the dynamic thermal throttling mechanism, it guarantees superior endurance and stability for high-end applications.

Speed may vary due to host hardware, software, usage, and storage capacity.
The workload used to rate DWPD may be different from your actual workload, which may vary due to host hardware, software, usage, and storage capacity.
Terabytes Written (TBW) expresses the endurance under the highest capacity.
Some motherboards only provide PCIe x2 connections for the M.2 slot, creating a bottleneck on even the fastest drives.

System Requirement
Operating System:
Microsoft Windows 7 or later
Linux Kernel 2.6.31 or later
Please make sure that your computer has a M.2 slot.
Systems for use with the PCIe M.2 SSD must have an M.2 connector with only an M key. B-key connectors are not compatible. Improper insertion may lead to damage. Please click here for more information.
