1 TB PCIe Gen 3x4 NVMe SSD

The Transcend PCIe SSD 115S provides one terabyte of storage using the PCIe Gen 3x4 interface and NVMe 1.4 protocol. Sequential reads reach 3,200 MB/s and writes reach 2,000 MB/s. The M.2 2280 form factor fits desktops, laptops and ultrabooks.

Limits of the PCIe Gen 3x4 interface

Four lanes carry data in both directions, capping throughput at the quoted speeds. The drive will not exceed the bandwidth ceiling of a Gen 3 link, so systems limited to that generation cannot benefit from faster NVMe standards. Thermal throttling activates under sustained heavy load to protect the controller.

M.2 2280 build and daily implications

3D TLC NAND flash is paired with LDPC error-correction coding to maintain data integrity over time. Dynamic thermal throttling manages heat without user intervention. The SSD Scope utility lets you monitor health and optimise performance from within the operating system.

Questions about this item

Should I choose the 1TB model or a different capacity for my upgrade?

The 1TB capacity gives ample space for operating systems, applications and large files while keeping the drive affordable.

What does the 3,200 MB/s read speed mean for everyday use?

Sequential reads up to 3,200 MB/s cut boot times and load large games or video projects noticeably faster than older drives.

How does the PCIe Gen3 x4 interface limit real-world performance?

Four PCIe 3.0 lanes cap sequential throughput at the stated 3,200 MB/s read and 2,000 MB/s write, so sustained transfers stay within those bounds.
